CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 31, 2023, with application number 202311438633.6 and application name “A Communication Method and Device”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the field of communication technology, and in particular to a communication method and device.

Background Art

Time division duplex (TDD) is widely used in the deployment of new radio (NR) wireless communication systems in the fifth generation (5G) mobile communication systems. TDD divides time domain resources into uplink and downlink.

For example, a possible TDD uplink/downlink resource configuration is DDDSU. D represents a downlink time slot, and each symbol in the downlink time slot is a downlink symbol; U represents an uplink time slot, and each symbol in the uplink time slot is an uplink symbol; S represents a special time slot, and a special time slot includes at least one flexible symbol. Limited uplink time domain resource allocation (for example, fewer resources are used for uplink transmission than for downlink transmission) leads to reduced uplink coverage and increased latency of TDD.

Summary of the invention

To address the above issues, one solution is to use subband full duplex (SBFD) (including overlapping SBFD (subband overlapping full duplex) and non-overlapping SBFD (subband non-overlapping full duplex)). SBFD divides the frequency band on the downlink symbol (and/or flexible symbol) into one or more uplink subbands and one or more downlink subbands, and allows uplink transmission on the uplink subband of the downlink symbol. Compared with TDD, SBFD has more uplink resources to improve the uplink coverage performance of terminal equipment, and each time slot has uplink resources for hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback to reduce latency.

In order to reduce the intermodulation interference of uplink transmission of terminal equipment, when the single-slot physical uplink control channel (PUCCH) and the multi-slot physical uplink shared channel (PUSCH) (such as PUSCH repetition type A, transport block processing over multi-slot (TBoMS) PUSCH (such as TBoMS PUSCH w/or w/o repetition), or PUSCH repetition type B) overlap or partially overlap in the time domain, one solution is to multiplex the uplink control information (UCI) carried on the PUCCH and send it on the PUSCH transmission in the overlapping time slot. However, when the channel environment on the SBFD symbol and the uplink symbol is quite different, when UCI multiplexing occurs on the SBFD symbol, the network device on the SBFD symbol will be subject to cross-link interference (CLI) from other network devices, which will seriously affect the reliability of UCI transmission. Therefore, the solution for UCI multiplexing needs further study.

The present application provides a communication method and apparatus for realizing effective multiplexing of UCI, thereby ensuring the reliability of UCI transmission.

In a first aspect, the present application provides a communication method, which can be performed by a first communication device.

Optionally, in a possible implementation manner provided in the third aspect or the fourth aspect, when the non-periodic CSI is multiplexed on the first transmission opportunity in the first PUSCH, if the second transmission opportunity does not include the SBFD symbol or the symbol allocated to the first PUSCH in the second transmission opportunity does not include the SBFD symbol, then the first transmission opportunity may be the second transmission opportunity; or,

If the second transmission opportunity includes a SBFD symbol or the symbol to which the first PUSCH is allocated in the second transmission opportunity includes a SBFD symbol, the first transmission opportunity may be a plurality of transmission opportunities to which the first PUSCH is allocated and which is located after the second transmission opportunity and satisfies one of the following conditions: The first transmission opportunity: does not include a SBFD symbol or the symbol to which the first PUSCH is allocated in the transmission opportunity does not include a SBFD symbol; or,

If the second transmission opportunity includes an SBFD symbol or the symbol allocated to the first PUSCH in the second transmission opportunity includes an SBFD symbol, and there is no transmission opportunity among the multiple transmission opportunities to which the first PUSCH is allocated that satisfies one of the following conditions after the second transmission opportunity: does not include an SBFD symbol or the symbol allocated to the first PUSCH in the transmission opportunity does not include an SBFD symbol, then the first transmission opportunity may be the second transmission opportunity.

In the above implementation, when the first transmission opportunity (i.e., the second transmission opportunity) among the multiple transmission opportunities to which the first PUSCH is allocated includes the SBFD symbol, by postponing the multiplexing of the aperiodic CSI to a transmission opportunity that does not include the SBFD symbol, or when the first transmission opportunity does not include the SBFD symbol, by multiplexing the aperiodic CSI on the first transmission opportunity. In this way, the implementation can improve the effectiveness and reliability of the aperiodic CSI multiplexing, thereby ensuring the reliability of the aperiodic CSI transmission.

Optionally, in a possible implementation manner provided in the third aspect or the fourth aspect, when the aperiodic CSI is multiplexed on at least one transmission opportunity in the first PUSCH,

The at least one transmission opportunity may be N consecutive transmission opportunities starting from the second transmission opportunity among the multiple transmission opportunities to which the first PUSCH is allocated; or,

At least one transmission opportunity may also be k transmission opportunities among the multiple transmission opportunities to which the first PUSCH is allocated, which are N consecutive transmission opportunities starting from the second transmission opportunity and satisfy one of the following items: only including SBFD symbols or the symbols to which the first PUSCH is allocated in the transmission opportunity only include SBFD symbols, wherein k is an integer greater than or equal to 1; or, at least one transmission opportunity may also be N consecutive transmission opportunities starting from the second transmission opportunity among the multiple transmission opportunities to which the first PUSCH is allocated and satisfy one of the following items: only including SBFD symbols or the symbols to which the first PUSCH is allocated in the transmission opportunity only include SBFD symbols.

In the above implementation, by repeatedly multiplexing the aperiodic CSI on multiple transmission opportunities, that is, it can be understood that the aperiodic CSI is repeatedly multiplexed multiple times, so that the reliability of the aperiodic CSI multiplexing can be improved, thereby ensuring the reliability of the aperiodic CSI transmission. In addition, by repeatedly multiplexing the aperiodic CSI on multiple transmission opportunities including only SBFD symbols (or it can be understood that each transmission opportunity in multiple transmission opportunities only includes SBFD symbols), the flexibility of PUSCH scheduling can be improved.

In a possible implementation manner provided in the third aspect or the fourth aspect, when the non-periodic CSI is multiplexed on the first actual repetition in the first PUSCH,

If the second actual repetition is not allocated SBFD symbols and the number of symbols allocated to the second actual repetition is greater than 1, the first actual repetition may be the second actual repetition; or,

If the second actual repetition is allocated SBFD symbols or the number of symbols allocated to the second actual repetition is less than or equal to 1, the first actual repetition may be the first actual repetition in the multiple actual repetitions included in the first PUSCH and located after the second actual repetition and meeting the following two conditions: no SBFD symbols are allocated, and the number of symbols allocated is greater than 1; or,

If the second actual repetition is allocated SBFD symbols or the number of symbols allocated to the second actual repetition is less than or equal to 1, and there is no actual repetition that satisfies the following two conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH: no SBFD symbols are allocated, and the number of symbols allocated is greater than 1, then the first actual repetition may be the second actual repetition; or,

If the second actual repetition is allocated SBFD symbols or the number of symbols allocated to the second actual repetition is less than or equal to 1, and there is no actual repetition in the multiple actual repetitions included in the first PUSCH that satisfies the following two conditions: no SBFD symbols are allocated and the number of symbols allocated is greater than 1, then the first actual repetition can be the first actual repetition in the multiple actual repetitions that is located after the second actual repetition and has the number of symbols allocated greater than 1.

In the above implementation, when the first actual repetition (such as the second actual repetition) among the multiple actual repetitions included in the first PUSCH is allocated with an SBFD symbol or the number of symbols allocated to the first actual repetition is less than or equal to 1, by postponing the multiplexing of the non-periodic CSI to the actual repetition that is not allocated with an SBFD symbol and the number of symbols allocated is greater than 1, or when the first actual repetition (such as the second actual repetition) among the multiple actual repetitions included in the first PUSCH is not allocated with an SBFD symbol and the number of symbols allocated to the first actual repetition is greater than 1, by multiplexing the non-periodic CSI on the first actual repetition. In this way, the implementation can improve the effectiveness and reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission.

In a possible implementation manner provided in the third aspect or the fourth aspect, when the non-periodic CSI is multiplexed on at least one actual repetition in the first PUSCH, the at least one actual repetition may be N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH; or,

The at least one actual repetition may be p actual repetitions among the multiple actual repetitions included in the first PUSCH and the consecutive N actual repetitions starting from the second actual repetition satisfying the following two conditions: only SBFD symbols are allocated, and the number of allocated symbols is greater than 1, where p is an integer greater than or equal to 1; or,

The at least one actual repetition may be N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH, which satisfy the following two conditions: only SBFD symbols are allocated, and the number of allocated symbols is greater than 1.

In the above implementation, by repeatedly multiplexing the aperiodic CSI on multiple actual repetitions, that is, it can be understood that the aperiodic CSI is repeatedly multiplexed multiple times, so that the reliability of the aperiodic CSI multiplexing can be improved, thereby ensuring the reliability of the aperiodic CSI transmission. In addition, by repeatedly multiplexing the aperiodic CSI on multiple actual repetitions that are only assigned SBFD symbols or only assigned SBFD symbols and the number of assigned symbols is greater than 1, the flexibility of PUSCH scheduling can be improved.

In a possible implementation manner provided by the third aspect or the fourth aspect, the method further includes: acquiring a first RRC message, wherein the first RRC message may include a number of repetitions of the aperiodic CSI, and the number of repetitions of the aperiodic CSI is included in at least one candidate number of the aperiodic CSI; or,

In a possible implementation manner provided in the third aspect or the fourth aspect, in the case where the non-periodic CSI is multiplexed on the first PUSCH transmission located in at least one time slot in the first PUSCH, if the first number of consecutive multiple time slots starting from the second time slot in the multiple time slots to which the first PUSCH is allocated is greater than or equal to the number of repetitions of the non-periodic CSI, then N may be the number of repetitions of the non-periodic CSI (it can be understood that the value of N is the number of repetitions of the non-periodic CSI), or, if the first number is less than the number of repetitions of the non-periodic CSI, then N may be the first number (it can be understood that the value of N is the first number); or,

In the case where the aperiodic CSI is multiplexed on at least one actual repetition in the first PUSCH, if a second number of consecutive actual repetitions starting from a second actual repetition among the multiple actual repetitions included in the first PUSCH is greater than or equal to the number of repetitions of the aperiodic CSI, then N may be the number of repetitions of the aperiodic CSI, or, if the second number is less than the number of repetitions of the aperiodic CSI, then N may be the second number; or,

In the case where the aperiodic CSI is multiplexed on the first PUSCH transmission located in at least one time slot in the first PUSCH, if a third number of consecutive time slots starting from the second time slot in the multiple time slots to which the first PUSCH is allocated that satisfy one of the following is greater than or equal to the number of repetitions of the aperiodic CSI: only SBFD symbols are included or the symbols to which the first PUSCH is allocated in the time slot only include SBFD symbols, then N may be the number of repetitions of the aperiodic CSI, or, if the third number is less than the number of repetitions of the aperiodic CSI, then N may be the third number; or,

DETAILED DESCRIPTION

Before introducing the technical solution provided by the present application, some of the terms involved in the present application are first explained to facilitate understanding by those skilled in the art.

(1) Slot: In the new radio (NR) system, a slot is defined to consist of 14 (or 12) orthogonal frequency-division multiplexing (OFDM) symbols. For the convenience of description, OFDM symbols may also be referred to as time domain symbols or symbols in the subsequent description of this application, and no further explanation is given. Among them, a slot may include downlink time domain symbols, uplink time domain symbols, and flexible time domain symbols. Downlink time domain symbols cannot be used for uplink transmission; uplink time domain symbols cannot be used for downlink transmission; and flexible time domain symbols can be used for both downlink and uplink transmission. The NR system supports one time slot for uplink transmission, denoted as the uplink (U) time slot, and all time domain symbols in this time slot are uplink time domain symbols; supports one time slot for downlink transmission, denoted as the downlink (D) time slot, and all time domain symbols in this time slot are downlink time domain symbols; it also supports the configuration of a time slot with both uplink and downlink, denoted as a special (S) time slot. A time slot includes at least two of a downlink time domain symbol, a flexible time domain symbol and an uplink time domain symbol.

(2) Symbol, short for time domain symbol, may also be referred to as orthogonal frequency-division multiplexing (OFDM). It should be noted that the time domain symbol may also be named in combination with other multiple access methods, which is not limited in the embodiments of the present application. The length of the time domain symbol may be different for different subcarrier spacings. The symbols in a time slot may include at least one of a downlink symbol, an uplink symbol and a flexible symbol. Among them, the uplink symbol may be used for uplink transmission, and the downlink symbol may be used for downlink transmission. Flexible symbols may be selectively used for uplink transmission, downlink transmission or protection interval. For example, flexible symbols may be used for uplink transmission, downlink transmission or protection interval based on the indication of control signaling.

(3) SBFD symbols: The symbols used by network devices for SBFD operation are defined as SBFD symbols, where the frequency resources on the SBFD symbols are divided into multiple sub-bands. For non-overlapping SBFD, the sub-bands are non-overlapping; for overlapping SBFD, the sub-bands can be overlapping. Sub-bands are divided into uplink sub-bands, downlink sub-bands, and flexible sub-bands. Uplink sub-bands are used for uplink transmission, downlink sub-bands are used for downlink transmission, and flexible sub-bands can be used for both uplink and downlink transmission.

(4) Non-SBFD symbols: Non-SBFD symbols may include uplink symbols, downlink symbols, and flexible symbols. Uplink symbols may be used for uplink transmission, and downlink symbols may be used for downlink transmission. Flexible symbols may be selectively used for uplink transmission, downlink transmission, or protection interval. For example, flexible symbols may be used for uplink transmission, downlink transmission, or protection interval based on the indication of control signaling. In the embodiment of the present application, since PUSCH cannot be sent in downlink symbols, non-SBFD symbols only include uplink symbols and flexible symbols unless otherwise specified.

FIG1a is a schematic diagram of a resource structure under TDD. As shown in FIG1a, the resources under TDD include 3 downlink time slots (indicated by D in FIG1a), 1 special time slot (indicated by S in FIG1a) and 1 uplink time slot (indicated by U in FIG1a). The resource structure illustrated in FIG1a can be simplified as DDDSU. Among them, a downlink time slot, an uplink time slot or a special time slot includes multiple symbols. The special time slot includes at least flexible symbols. Under TDD, the downlink time slot is used for downlink transmission, the uplink time slot is used for uplink transmission, and the special time slot can be flexibly used for uplink or downlink transmission.

Figure 1b is a schematic diagram of a resource structure under SBFD. As shown in Figure 1b, the resources include 5 downlink time slots. These 5 downlink time slots can correspond to one or more uplink sub-bands (such as U shown in Figure 1b), and these uplink sub-bands can be used for uplink transmission. The resource structure shown in Figure 1b can be simplified as XXXXX. X can be used to represent a time slot including at least one SBFD symbol. Furthermore, in an embodiment of the present application, in order to facilitate the introduction of the communication scheme provided in an embodiment of the present application, taking the example that all symbols included in the time slot are SBFD symbols, such a time slot is recorded as time slot X. The frequency unit on the SBFD symbol can be used for multiple transmissions, for example, for uplink transmission and downlink transmission.

FIG1c is a schematic diagram of another resource structure under SBFD. As shown in FIG1c, the resources include 3 downlink time slots, 1 special time slot and 1 uplink time slot. The 3 downlink time slots and 1 special time slot can correspond to one or more uplink subbands (such as U shown in FIG1c), and these uplink subbands can be used for uplink transmission. The resource structure shown in FIG1c can be simplified as XXXXU.

FIG1d is a schematic diagram of another resource structure under SBFD. As shown in FIG1d, the resources include 3 downlink time slots, 1 special time slot and 1 uplink time slot. Two of the 3 downlink time slots can correspond to one or more uplink sub-bands, and one special time slot can also correspond to one or more uplink sub-bands (such as U shown in FIG1d), and these uplink sub-bands can be used for uplink transmission. The resource structure shown in FIG1d can be simplified as DXXXU.

(5) Physical uplink shared channel (PUSCH) repetition type A and PUSCH repetition type B:

In the current NR system, two types of repeated transmissions are supported for PUSCH: PUSCH repetition type A and PUSCH repetition type B. PUSCH repetition type A and PUSCH repetition type B are introduced as follows:

a. PUSCH repetition type A: In 3GPP R15 (Release 15), a PUSCH transmission is not allowed to cross the time slot boundary. Therefore, in order to avoid transmitting PUSCH across the slot boundary, the terminal device (such as UE) can cooperate with the repeated transmission of PUSCH in consecutive available slots through uplink (UL) grant or radio resource control (RRC) signaling, which is called PUSCH repetition type A), where the time domain resources for the repeated transmission of PUSCH in each slot are the same.

b. PUSCH repetition type B: PUSCH repetition type B is newly added in the R16 (Release 16) protocol of 3GPP. For PUSCH repetition type B, the time domain resource allocation (TDRA) field in the downlink control information (DCI) or the TDRA parameter in the type1 configured grant (CG) scheduling indicates the resources of the first "nominal" repetition, and the time domain resources of the remaining repetition transmissions are calculated based on the time domain resources of the first PUSCH and the UL/downlink (DL) time slot configuration. If the nominal repetition crosses the time slot boundary or DL/UL switching point, and the invalid symbol (s) defined in the standard TS 38.214, the nominal repetition can be split into multiple actual repetitions at the time slot boundary or DL/UL switching point and the invalid symbol (s) defined in the standard TS 38.214, so the number of actual repetitions can be greater than the indicated value.

(6) Channel state information (CSI) report: After receiving the CSI reference signal (CSI-RS) sent by the network device, the terminal device will send a CSI report to the network device. CSI reports can be divided into the following three categories:

a. Periodic (or periodic) CSI report (P-CSI report): usually transmitted in the Physical Uplink Control Channel (PUCCH). Once the network device configures the periodic CSI report for the terminal device, the terminal device will send the CSI report according to the configured period. That is, the time domain position of the periodic CSI report is semi-statically configured through RRC signaling.

b. Semi-persistence CSI report (SP-CSI report): Like periodic CSI report, it is usually transmitted in PUCCH. However, the difference from periodic CSI report is that semi-persistence CSI report needs to be activated again after the network device configures it for the terminal device. After activation, its time domain position can be considered as semi-statically configured through RRC signaling.

c. Aperiodic (or aperiodic) CSI report (AP-CSI report): Transmitted in PUSCH and triggered by DCI. Specifically, if the network device sends a DCI in time slot n, in addition to indicating the K2 value, the DCI may also contain an aperiodic CSI trigger information. If the DCI contains aperiodic CSI trigger information, the terminal device will carry the aperiodic CSI report in the scheduled PUSCH.

(7) Uplink control information (UCI): Due to the different service types of terminal devices, UCI has multiple specific types. For example, in the NR system, UCI can be a scheduling request (SR) or a link recovery request (LRR) in addition to the above-mentioned HARQ-ACK and CSI. Since different types of UCI have their own independent time domain behaviors, terminal devices often encounter situations where they need to reuse one UCI to send the information included in multiple UCIs.

(8) Transmission Occasion (TO): For PUSCH, PUSCH repetition type A and TBoMS PUSCH w/or w/o repetition, a transmission occasion is defined as L consecutive symbols starting from the start symbol S in one of the one or more time slots allocated to PUSCH, PUSCH repetition type A and TBoMS PUSCH w/or w/o repetition, where the start symbol S, the symbol length L, and the first time slot and the number of time slots in the one or more allocated time slots are configured by the network device. Alternatively, it can be understood that a transmission occasion is defined as all symbols allocated for PUSCH transmission in one time slot. For PUSCH repetition type B, a transmission occasion is defined as a nominal repetition.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The following is an introduction to possible communication system architectures applicable to the communication method provided in this application. It should be noted that these introductions are for the convenience of understanding by those skilled in the art and do not limit the scope of protection claimed in this application.

FIG2 exemplarily shows a possible communication system architecture schematic diagram applicable to the embodiment of the present application. As shown in FIG2 , the communication system architecture includes a terminal device 100 and a network device 200. It should be understood that the number of devices (such as terminal devices 100, network devices 200, etc.) in the communication system architecture shown in FIG2 is only an example and does not constitute a limitation on the technical solution provided in the embodiment of the present application. For example, the number of terminal devices 100 can be one or more, and the number of network devices 200 can be one or more.

Optionally, the terminal device 100 can be connected to the network device 200 (such as a (R)AN device) in a wireless manner. For example, the network device 200 can send a downlink signal (or downlink data or downlink information) to the terminal device 100, and the terminal device can receive the downlink signal (or downlink data or downlink information) sent by the network device. The terminal device 100 can also send an uplink signal (or uplink data or uplink information) to the network device 200, and the network device 200 can receive the uplink signal sent by the terminal device 100. Exemplarily, the communication system architecture can also include other network devices (such as wireless relay devices or wireless backhaul devices, etc.).

The following is a brief introduction to the functions of some devices included in the communication system architecture.

Terminal device 100: It is an entity on the user side that has the function of sending and receiving signals, and can provide users with service functions such as video, voice, and data connectivity. For example, terminal device 100 is the entrance for mobile users to interact with the network, and can provide basic computing power and storage capacity, and can display service windows to users and receive user operation input. The next generation terminal equipment (NextGen UE) can use new air interface technology to establish signal connections and data connections with network equipment, thereby transmitting control signals and service data to the mobile network.

Optionally, the terminal device 100 may also be referred to as a terminal, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal equipment, mobile device, UE terminal equipment, terminal equipment, wireless communication equipment, UE agent or UE device, etc. In an embodiment of the present application, the terminal device 100 may be fixed or mobile, and the implementation of the present application does not limit this. Exemplarily, the terminal device 100 may be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted, or may be deployed on water (such as a ship, etc.), or may be deployed in the air (such as an airplane, a balloon or a satellite, etc.).

Exemplarily, the terminal device 100 may be a mobile phone, a tablet computer, a customer-premises equipment (CPE), a subscriber unit, a cellular phone, a smart phone, a wireless data card, a personal digital assistant (PDA), a computer, a wireless modem, a handheld device (handset), a laptop computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, or a wireless communication device. The present invention relates to wireless terminals in the following aspects: wireless terminals in the smart grid, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable terminal devices, vehicles, drones, helicopters, airplanes, factory machines/equipment, machine type communication (MTC) terminals, ships or robots, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal equipment.

Network device 200: is a device that connects a terminal device (such as terminal device 100) to a wireless network. For example, network device 200 can provide network access functions for authorized users in a specific area, and can determine transmission tunnels of different qualities to transmit user data according to the user's level, business requirements, etc. The network device can manage its own resources, use them reasonably, provide access services to terminal devices on demand, and is responsible for forwarding control signals and user data between terminal device 100 and the core network.

Exemplarily, the network device 200 may include, but is not limited to, a next generation base station (next generation NodeB, gNB) in a fifth generation (5G) communication system, a next generation base station in a sixth generation (6G) communication system, a base station in a future communication system, a transmission reception point (TRP), an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a base band unit (BBU), or a wireless fidelity (Wi-Fi) access point (AP), etc.

Optionally, in a network structure, the network device 200 may also include a centralized unit (CU) or a distributed unit (DU). This structure can split the protocol layer of the network device 200, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU. For example, the functions of the packet data convergence protocol (PDCP) layer and above can be set in the CU, and the functions of the protocol layers below the PDCP (such as the RLC layer and the medium access control (MAC) layer, etc.) are set in the DU. It should be noted that this division of the protocol layer is only an example, and it can also be divided in other protocol layers. The radio frequency device can be remote and not placed in the DU, or it can be integrated in the DU, or part of it can be remotely located and part of it can be integrated in the DU, and the embodiments of the present application do not impose any restrictions. In addition, in some embodiments, the control plane (CP) and user plane (UP) of the CU can be separated and implemented by different entities, namely, the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity).

In this network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU can directly encapsulate the signaling through the protocol layer and transparently transmit it to the terminal device or CU without parsing it. In this network architecture, the CU is divided into a network device on the radio access network (RAN) side. In addition, the CU can also be divided as a network device on the core network (CN) side, and this application does not limit this.

Optionally, in some embodiments, the network device may also be a server, a wearable device, or a vehicle-mounted device, etc.

Exemplarily, the network device 200 is taken as a base station for explanation. Multiple network devices 200 may be base stations of the same type or different types. The base station may communicate with the terminal device 100, or may communicate with the terminal device 100 through a relay station. Optionally, the terminal device 100 may communicate with multiple network devices 200 equipped with different communication technologies. For example, the terminal device 100 may communicate with a base station equipped with an LTE network, or may communicate with a base station equipped with a 5G network, and may also support dual connection with a base station equipped with an LTE network and a base station equipped with a 5G network.

It is understandable that the network device and the terminal device can communicate through the licensed spectrum, the unlicensed spectrum, or both the licensed spectrum and the unlicensed spectrum. The network device and the terminal device can communicate through the spectrum below the sixth generation mobile communication system (6th generation mobile networks or 6th generation wireless systems, 6G), the spectrum above 6G, or the spectrum below 6G and the spectrum above 6G at the same time. The embodiment of the present application does not limit the spectrum resources used between the network device and the terminal device.

Optionally, the communication system illustrated in FIG. 2 may be any type of communication system, for example, an Internet of Things (IoT) system, a narrowband Internet of Things (NB-IoT) system, a long term evolution (LTE) system, or a LTE-M system. The present invention relates to a 5G network, a 5G network or a 5G network, and a 5G network. The present invention relates to ...

The following is a detailed introduction to the specific implementation of the communication method in the embodiment of the present application based on the communication system architecture shown in FIG. 2 .

[Example 1]

FIG3 exemplarily shows a flow chart of a communication method provided in Example 1 of the present application. The method is applicable to the communication system architecture illustrated in FIG2 . The method flow may be implemented by data interaction between multiple communication devices (such as a first communication device and a second communication device). Optionally, the first communication device may be a terminal device or a component (such as a chip, a chip system or a circuit, etc.) that can support the terminal device to implement the functions required for the method, or other devices having the functions of the terminal device, or other functional modules having the functions of implementing the communication method, and the second communication device may be a network device or a component (such as a chip, a chip system or a circuit, etc.) that can support the network device to implement the functions required for the method, or other devices having the functions of the network device, or other functional modules having the functions of implementing the communication method. Exemplarily, the terminal device may be the terminal device 100 illustrated in FIG2 , and the network device may be the network device 200 illustrated in FIG2 . It can be understood that the communication method illustrated in Figure 3 is applicable to the following application scenarios: one piece of information (such as the first information) sent by the network device is used to schedule the terminal device to send the first transmission block, and another piece of information (such as the second information) sent by the network device is used to schedule the terminal device to send the first UCI (such as CSI or CSI and HARQ-ACK), the first transmission block is carried on the first PUSCH, the first UCI is carried on the first PUCCH, and the first PUSCH overlaps or partially overlaps with the first PUCCH in the time domain. In order to facilitate the introduction of the technical solution provided in Example 1 of the present application, the following takes the first communication device as a terminal device and the second communication device as a network device as an example to introduce the process of implementing the communication method through data interaction between the first communication device and the second communication device. As shown in Figure 3, the method includes:

Step 301: The network device sends the first information and the second information. Correspondingly, the terminal device receives the first information and the second information.

Optionally, in an embodiment of the present application, if the terminal device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the received information comes from; if the network device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the sent information is sent to.

Optionally, if the network device is a distributed architecture, for example, the network device includes a CU and/or a DU, or includes one or more of a CU-CP, a CU-UP, or a DU, when the network device includes a DU, the network device sends the first information and the second information, and specifically, the DU included in the network device sends the first information and the second information. Optionally, the network device including the DU may also include a CU; or, the network device including the DU may also include a CU-CP and/or a CU-UP.

For example, the first information may be DCI or RRC, etc., and the second information may be DCI or RRC, etc.

The first information may be used to indicate the sending of a first transport block (TB), and the first transport block is carried on a first PUSCH. Optionally, the first PUSCH may refer to a PUSCH to which multiple time slots are allocated, or the first PUSCH may refer to a PUSCH including multiple actual repetitions. For example, the first PUSCH may include one of the following: PUSCH repetition type A, PUSCH repetition type B, TBoMS PUSCH or TBoMS PUSCH repetition, etc., that is, the first PUSCH may be one of PUSCH repetition type A, PUSCH repetition type B, TBoMS PUSCH or TBoMS PUSCH repetition (repetition), etc. TBoMS PUSCH and TBoMS PUSCH repetition may be jointly simplified as: TBoMS PUSCH w/or w/orepetition. For example, when the first PUSCH is PUSCH repetition type A or TBoMS PUSCH w/or w/o repetition, the first PUSCH may be allocated multiple time slots. When the first PUSCH is PUSCH repetition type B, the first PUSCH may include multiple actual repetitions. It should be understood that the multiple actual repetitions included in PUSCH repetition type B may be located in one time slot, or may be located in multiple time slots, and the embodiments of the present application are not limited to this.

The second information may be used to indicate that the first UCI is to be sent, and the first UCI is carried on the first PUCCH. Optionally, the first PUCCH may be a single-slot PUCCH.

The first PUSCH overlaps with the first PUCCH in the time domain. It should be understood that the first PUSCH overlaps with the first PUCCH in the time domain can be understood as the first PUSCH and the first PUCCH completely overlap in the time domain (or can be called full overlap), or can also be understood as the first PUSCH and the first PUCCH partially overlap in the time domain. For example, the first PUSCH is PUSCH repetition Taking type A as an example, assume that PUSCH repetition type A is allocated 3 time slots (such as time slot 1, time slot 2 and time slot 3). Among them, each time slot corresponds to (or is associated with) a PUSCH (or can be called PUSCH transmission), time slot 1 is located before time slot 2, and time slot 3 is located after time slot 2. Figure 4a is a schematic diagram of the overlap of a first PUSCH and a first PUCCH in the time domain provided in Example 1 of the present application. As shown in Figure 4a, the PUSCH located in time slot 2 and the first PUCCH (abbreviated as PUCCH in Figure 4a) are completely overlapped. Figure 4b is another schematic diagram of the overlap of a first PUSCH and a first PUCCH in the time domain provided in Example 1 of the present application. As shown in Figure 4b, the PUSCH located in time slot 2 and the first PUCCH (abbreviated as PUCCH in Figure 4b) are partially overlapped.

Step 302: The terminal device sends a first transmission block and a first UCI. Correspondingly, the network device receives the first transmission block and the first UCI from the terminal device.

In an embodiment of the present application, when the first PUSCH and the first PUCCH overlap in the time domain, after the terminal device obtains the first information and the second information from the network device, the first UCI can be multiplexed (or can be called a carrier) on the first PUSCH for transmission (or sending), thereby reducing the intermodulation interference of the uplink transmission of the terminal device. However, since the first UCI multiplexing (multiplexing) on the first PUSCH has a problem of low transmission reliability (for example, when the first UCI is multiplexed on the PUSCH transmission located on the SBFD symbol, the channel environment on the SBFD symbol is different from the channel environment on the uplink symbol (for example, the network device will be affected by the CLI of other network devices on the SBFD symbol), resulting in poor reliability of the first UCI transmission), in order to solve this problem, the terminal device can, but is not limited to, adopt the following possible solutions to achieve effective multiplexing of the first UCI on the first PUSCH, thereby improving the reliability (or stability) of the first UCI transmission.

Solution 1: The terminal device postpones the multiplexing of the first UCI.

The following describes several possible implementations of the terminal device postponing the multiplexing of the first UCI.

Implementation method 1: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition), the terminal device may multiplex the first UCI on the first PUSCH transmission in the first time slot in the first PUSCH.

It can be understood that the first UCI is multiplexed on the first PUSCH transmission in the first time slot in the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition), and it can be understood that the first UCI is carried on the first PUSCH transmission in the first time slot in the first PUSCH, or it can be understood that the first UCI is sent (or transmitted) on the first PUSCH transmission in the first time slot in the first PUSCH.

It should be understood that the first time slot is one of a plurality of time slots to which the first PUSCH is allocated.

Several possible ways of determining the first time slot are introduced below.

Method 1: The terminal device may use the time slot that meets the first condition among the multiple time slots allocated to the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition) as the first time slot.

For example, the first condition may be any one of the following two possible conditions.

Condition 1: SBFD symbols are not included.

It should be understood that, under the following condition, the first time slot is a time slot that does not include SBFD symbols among the multiple time slots allocated to the first PUSCH, that is, it can be understood that the first time slot is a time slot that can only include non-SBFD symbols (such as uplink symbols and/or flexible symbols).

Condition 2: the symbols allocated to the first PUSCH in the time slot do not include SBFD symbols.

It should be understood that under condition 2, the first time slot may include SBFD symbols, but the symbols allocated to the first PUSCH in the first time slot cannot include SBFD symbols, that is, the symbols indicated by the start and length indicator (Start and Length indicator Value, SLIV) (or the start symbol S or the length L) cannot include SBFD symbols. Among them, SLIV (or S or L) can be included in the PUSCH allocation table (PUSCH Allocation List) in the RRC signaling. For example, the PUSCH allocation table includes at least one of the following fields: startSymbol or Length. Among them, startSymbol is used to indicate the start symbol S of the first symbol, and Length is used to indicate the length L of the first symbol. Optionally, the symbols allocated to the first PUSCH in the first time slot cannot include SBFD symbols, which can also be understood as the symbols allocated to the first PUSCH in the first time slot only include non-SBFD symbols (such as uplink symbols and/or flexible symbols).

Method 2: The terminal device can determine the first time slot based on the second time slot. The second time slot is the time slot where the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of the TBoMS PUSCH repetitions) overlaps with the first PUCCH. It can be understood that the terminal device determines the first time slot based on the second time slot as a reference time slot.

The following describes the implementation process of the terminal device determining the first time slot based on the second time slot through the following possible examples.

Example 1: When the second time slot satisfies the first condition (i.e., the second time slot does not include an SBFD symbol, or the symbol allocated to the first PUSCH in the second time slot does not include an SBFD symbol), the terminal device may use the second time slot as (or determine it to be) the first time slot. In other words, when the second time slot satisfies the first condition, the terminal device determines that the first time slot is the second time slot.

For example, when the time slot where the first PUSCH overlaps with the first PUCCH (i.e., the second time slot) satisfies the first condition (or is reasonable), When the overlap between the first PUSCH and the first PUCCH in the time domain occurs in a non-SBFD symbol), the terminal device may multiplex the first UCI on the PUSCH transmission in the time slot where the overlap occurs.

Exemplarily, taking the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), and there is a partial overlap between the first PUSCH and the first PUCCH (abbreviated as PUCCH in Figure 5a), and the time slot where the partial overlap occurs is time slot 2 (that is, the PUSCH on time slot 2 overlaps with the PUCCH), time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 5a is a schematic diagram of a first UCI multiplexing provided in Example 1 of the present application. As shown in Figure 5a, when time slot 2 does not include an SBFD symbol or the symbol allocated to the first PUSCH in time slot 2 does not include an SBFD symbol, the terminal device can multiplex the first UCI on the PUSCH transmission on time slot 2. For example, time slot 0, time slot 2, time slot 3, and time slot 4 shown in Figures 5a to 5e can be respectively one of the downlink time slot D, the time slot X that only includes SBFD symbols, or the uplink time slot U. For example, time slot 0 is the downlink time slot D, time slot 1, time slot 2, and time slot 3 are all time slot X that only includes SBFD symbols, and time slot 4 is the uplink time slot U.

Example 2: When the second time slot does not satisfy the first condition (i.e., the second time slot includes an SBFD symbol, or the symbol allocated to the first PUSCH in the second time slot includes an SBFD symbol), the terminal device may use the first time slot that satisfies the first condition and is located after the second time slot among the multiple time slots to which the first PUSCH is allocated as the first time slot. In other words, the terminal device may determine that the first time slot is the first time slot that satisfies one of the following (which may be understood as any one of the following) among the multiple time slots to which the first PUSCH is allocated and is located after the second time slot: does not include an SBFD symbol or the symbol allocated to the first PUSCH in the time slot does not include an SBFD symbol (or it may be referred to as the symbol allocated to the first PUSCH in the time slot does not include an SBFD symbol).

For example, when the time slot where the first PUSCH overlaps with the first PUCCH (i.e., the second time slot) does not satisfy the first condition (or it can be understood that the overlap between the first PUSCH and the first PUCCH in the time domain occurs on the SBFD symbol), the terminal device can postpone the multiplexing of the first UCI to the PUSCH transmission on the non-SBFD symbol (such as the PUSCH transmission in the first time slot that satisfies the first condition and is located after the second time slot in the multiple time slots to which the first PUSCH is allocated).

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, assume that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), and there is a partial overlap between the first PUSCH and the first PUCCH (abbreviated as PUCCH in Figure 5b), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 5b is another schematic diagram of the first UCI multiplexing provided in Example 1 of the present application. As shown in Figure 5b, take time slot 4 located after time slot 2 as the first time slot that meets the first condition. When time slot 2 includes an SBFD symbol or the symbol allocated to the first PUSCH in time slot 2 includes an SBFD symbol, the terminal device can first determine the first time slot that meets the first condition after time slot 2, that is, time slot 4. In other words, time slot 4 is the first time slot after time slot 2 that does not include an SBFD symbol, or time slot 4 is the first time slot after time slot 2 in which the symbol allocated to the first PUSCH does not include an SBFD symbol. Afterwards, the terminal device can postpone the multiplexing of the first UCI to the PUSCH transmission on time slot 4.

Optionally, in the case where time slot 2 includes a SBFD symbol or the symbol allocated to the first PUSCH in time slot 2 includes a SBFD symbol, it is assumed that the terminal device determines that time slot 3 located after time slot 2 is the first time slot that satisfies the first condition. In other words, time slot 3 is the first time slot after time slot 2 that does not include a SBFD symbol, or time slot 3 is the first time slot after time slot 2 in which the symbol allocated to the first PUSCH does not include a SBFD symbol. Thereafter, the terminal device may defer multiplexing of the first UCI to the PUSCH transmission on time slot 3.

Example three: When the second time slot does not meet the first condition, and there is no time slot meeting the first condition after the second time slot in the multiple time slots allocated to the first PUSCH (that is, there is no time slot meeting one of the following items (which can be understood as any one of the following items) after the second time slot in the multiple time slots allocated to the first PUSCH: does not include an SBFD symbol or the symbols allocated to the first PUSCH in the time slot do not include an SBFD symbol), the terminal device may use the second time slot as the first time slot.

For example, when the time slot where the first PUSCH overlaps with the first PUCCH (i.e., the second time slot) does not meet the first condition, and there is no time slot meeting the first condition after the time slot where the overlap occurs in the multiple time slots allocated to the first PUSCH, the terminal device can multiplex the first UCI on the PUSCH transmission in the time slot where the overlap occurs.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, assume that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), there is a partial overlap between the first PUSCH and the first PUCCH, and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. When time slot 2 includes an SBFD symbol or the symbol allocated to the first PUSCH in time slot 2 includes an SBFD symbol, and time slot 3 and time slot 4 located after time slot 2 do not meet the first condition When the first condition is not met in time slot 3, the terminal device may multiplex the first UCI on the PUSCH transmission in time slot 2. For time slot 3, the first condition is not met, which can be understood as time slot 3 including SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 including SBFD symbols. For time slot 4, the first condition is not met, which can be understood as time slot 4 including SBFD symbols, or the symbols allocated to the first PUSCH in time slot 4 including SBFD symbols.

Optionally, the above-mentioned method 1 and method 2 can be implemented separately as a solution, or can be combined and implemented as a solution.

In the case where the first PUSCH and the first PUCCH overlap in the time domain, compared to the existing solution of multiplexing the first UCI on the overlapping PUSCH transmission, when the overlapping portion includes SBFD symbols, the implementation method 1 in the above-mentioned scheme 1 can improve the effectiveness and reliability of the first UCI multiplexing by postponing the multiplexing of the first UCI to the PUSCH transmission on the non-SBFD symbol, thereby ensuring the reliability of the first UCI transmission. In addition, when the overlapping portion does not include SBFD symbols, the implementation method 1 in the above-mentioned scheme 1 can also multiplex the first UCI on the PUSCH transmission of the overlapping portion, thereby ensuring that the transmission of the first UCI is not affected, thereby ensuring the reliability of the first UCI transmission.

Implementation method 2: When the first PUSCH is PUSCH repetition type B, the terminal device may multiplex the first UCI on the first actual repetition (actual repetition, or referred to as actual PUSCH repetition) in the first PUSCH.

It can be understood that the first UCI is multiplexed on the first actual repetition in the first PUSCH (such as PUSCH repetition type B), which can be understood as the first UCI is carried on the first actual repetition in the first PUSCH, or it can be understood as the first UCI is sent on the first actual repetition in the first PUSCH.

It should be understood that the first actual repetition is one of multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B).

Several possible ways of determining the first actual repetition are described below.

Method 1: The terminal device may use the actual repetition that meets the second condition and/or the third condition among multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B) as the first actual repetition.

For example, the second condition is: no SBFD symbols are allocated, and the third condition is: the number of allocated symbols is greater than 1. For the first actual repetition to satisfy the second condition and/or the third condition, it can be understood that the first actual repetition is not allocated SBFD symbols, or the number of symbols allocated to the first actual repetition is greater than 1, or the first actual repetition is allocated SBFD symbols and (and) the number of allocated symbols is greater than 1.

Exemplarily, taking the first actual repetition as an actual repetition that satisfies the second condition among multiple actual repetitions included in the first PUSCH as an example, the first actual repetition is an actual repetition that is not allocated SBFD symbols among the multiple actual repetitions included in the first PUSCH, that is, it can be understood that the first actual repetition is an actual repetition that is only allocated on uplink symbols and/or flexible symbols.

Mode 2: The terminal device may determine the first actual repetition based on the second actual repetition. The second actual repetition is the first actual repetition in the first PUSCH (such as PUSCH repetition type B) that overlaps with the first PUCCH in the time domain and has a number of symbols allocated that is greater than 1. It can be understood that the terminal device determines the first actual repetition using the second actual repetition as a reference actual repetition.

The following describes the implementation process of the terminal device determining the first actual repetition according to the second actual repetition through the following possible examples.

Example 1: When the second actual repetition satisfies the second condition (ie, the second actual repetition is not allocated SBFD symbols), the terminal device may use the second actual repetition as the first actual repetition. In other words, when the second actual repetition satisfies the second condition, the terminal device determines the first actual repetition as the second actual repetition.

For example, when the first actual repetition (i.e., the second actual repetition) in the first PUSCH overlaps with the first PUCCH in the time domain and the number of allocated symbols is greater than 1 is not allocated SBFD symbols, the terminal device can multiplex the first UCI on the second actual repetition that is not allocated SBFD symbols.

Exemplarily, taking the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (referred to as PUCCH in FIG. 5c ) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. FIG5c is another schematic diagram of first UCI multiplexing provided in Embodiment 1 of the present application. As shown in FIG5c, actual repetition 3 is taken as an example of the first actual repetition in the first PUSCH that overlaps with the first PUCCH in the time domain and the number of symbols allocated is greater than 1. In other words, actual repetition 3 is the first actual repetition in the first PUSCH that overlaps with the first PUCCH in the time domain and the number of symbols allocated is greater than 1. Repetition 3 is used as the second actual repetition. When actual repetition 3 is not allocated SBFD symbols (ie, symbols allocated to actual repetition 3 in slot 2 do not include SBFD symbols), the terminal device may multiplex the first UCI on actual repetition 3.

Optionally, it is assumed that actual repetition 4 is the first actual repetition in the first PUSCH that overlaps with the first PUCCH in the time domain and the number of symbols allocated is greater than 1. In other words, actual repetition 4 is the second actual repetition. When actual repetition 4 is not allocated SBFD symbols (that is, the symbols allocated to actual repetition 4 in time slot 2 do not include SBFD symbols), the terminal device can multiplex the first UCI on actual repetition 4.

Example 2: When the second actual repetition does not satisfy the second condition (i.e., the second actual repetition is allocated SBFD symbols), the terminal device may use the first actual repetition that satisfies the second condition and the third condition and is located after the second actual repetition among the multiple actual repetitions included in the first PUSCH as the first actual repetition. In other words, the terminal device may determine that the first actual repetition is the first actual repetition that satisfies the following two conditions and is located after the second actual repetition among the multiple actual repetitions included in the first PUSCH: is not allocated SBFD symbols, and the number of allocated symbols is greater than 1.

For example, when the first actual repetition (i.e., the second actual repetition) in the first PUSCH that overlaps with the first PUCCH in the time domain and has a number of allocated symbols greater than 1 is allocated SBFD symbols, the terminal device can postpone the multiplexing of the first UCI to the first actual repetition among the multiple actual repetitions included in the first PUSCH that is located after the second actual repetition and meets the second and third conditions.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (abbreviated as PUCCH in FIG. 5d) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 5d is another schematic diagram of the first UCI multiplexing provided in the first embodiment of the present application. As shown in Figure 5d, take actual repetition 3 as the second actual repetition as an example. When actual repetition 3 is assigned an SBFD symbol, the terminal device can first determine the first actual repetition that meets the second condition and the third condition after actual repetition 3, such as actual repetition 7. In other words, actual repetition 7 is the first actual repetition that meets the second condition and the third condition after actual repetition 3. Afterwards, the terminal device can postpone the first UCI multiplexing to actual repetition 7.

Example three: When the second actual repetition does not satisfy the second condition, and there is no actual repetition that satisfies the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH (that is, there is no actual repetition that satisfies the following two conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH: no SBFD symbols are allocated, and the number of allocated symbols is greater than 1), the terminal device may take the second actual repetition as the first actual repetition.

For example, when the first actual repetition (i.e., the second actual repetition) in the first PUSCH that overlaps with the first PUCCH in the time domain and has a number of allocated symbols greater than 1 is allocated an SBFD symbol, and there is no actual repetition that meets the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH, the terminal device can multiplex the first UCI on the second actual repetition allocated the SBFD symbol.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, there is a partial overlap between the first PUSCH and the first PUCCH (for example, both actual repetition 3 and actual repetition 4 overlap with the first PUCCH in the time domain), and the time slot where the partial overlap is located is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. For example, continuing to take actual repetition 3 as the second actual repetition as an example. When actual repetition 3 is allocated SBFD symbols, and actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7 located after actual repetition 3 do not meet the second condition and the third condition, the terminal device can multiplex the first UCI on actual repetition 3.

Example 4: When the second actual repetition does not satisfy the second condition, and there is no actual repetition satisfying the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH, the terminal device may take the first actual repetition that satisfies the third condition (i.e., the number of symbols allocated is greater than 1) after the second actual repetition among the multiple actual repetitions included in the first PUSCH as the first actual repetition. In other words, the terminal device may determine that the first actual repetition is the first actual repetition that is located after the second actual repetition among the multiple actual repetitions included in the first PUSCH and the number of symbols allocated is greater than 1.

For example, when the first actual repetition (i.e., the second actual repetition) in the first PUSCH that overlaps with the first PUCCH in the time domain and has a number of allocated symbols greater than 1 is allocated an SBFD symbol, and there is no actual repetition that meets the second and third conditions after the second actual repetition in the multiple actual repetitions included in the first PUSCH, the terminal device can postpone the multiplexing of the first UCI to the first actual repetition that meets the third condition and is located after the second actual repetition in the multiple actual repetitions included in the first PUSCH.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (abbreviated as PUCCH in FIG. 5e) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 5e is another schematic diagram of the first UCI multiplexing provided in Example 1 of the present application. As shown in Figure 5e, actual repetition 3 is taken as the second actual repetition as an example. When actual repetition 3 is assigned an SBFD symbol, and actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7 that are located after actual repetition 3 do not meet the second condition and the third condition, the terminal device can first determine the first actual repetition that meets the third condition after actual repetition 3, such as actual repetition 5. In other words, actual repetition 5 is the first actual repetition that meets the third condition after actual repetition 3. Afterwards, the terminal device can postpone the multiplexing of the first UCI to actual repetition 5.

In the case where the first PUSCH and the first PUCCH overlap in the time domain, compared to the existing solution of multiplexing the first UCI on the actual repetition where the overlap occurs (such as the second actual repetition), when the second actual repetition is allocated with SBFD symbols, the second implementation method in the above-mentioned scheme one postpones the multiplexing of the first UCI to the actual repetition that is not allocated with SBFD symbols and the number of allocated symbols is greater than 1 (such as the first actual repetition that is not allocated with SBFD symbols and the number of allocated symbols is greater than 1 after the second actual repetition), thereby improving the effectiveness and reliability of the first UCI multiplexing, thereby ensuring the reliability of the first UCI transmission. In addition, when the second actual repetition is not allocated with SBFD symbols, the second implementation method in the above-mentioned scheme one may also multiplex the first UCI on the second actual repetition, thereby ensuring that the transmission of the first UCI is not affected, thereby ensuring the reliability of the first UCI transmission.

Solution 2: The terminal device repeats the multiplexing of the first UCI (or it can be understood that the terminal device repeatedly multiplexes the first UCI multiple times, for example, the terminal device may repeat multiplexing the first UCI on PUSCH transmissions in multiple time slots in the first PUSCH, or may repeat multiplexing the first UCI on multiple actual repetitions in the first PUSCH).

The following describes the multiplexing of the first UCI repeated by the terminal device through the following possible implementation methods.

Implementation method 1: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition), the terminal device may multiplex the first UCI on the first PUSCH transmission located in at least one time slot (one or more time slots (for example, at least two time slots)) among the multiple time slots allocated to the first PUSCH.

It can be understood that the first UCI is multiplexed on the first PUSCH transmission located in at least one time slot among the multiple time slots allocated to the first PUSCH. It can be understood that the first UCI is carried on the first PUSCH transmission located in at least one time slot among the multiple time slots allocated to the first PUSCH, and the first UCI is sent on the first PUSCH transmission located in at least one time slot among the multiple time slots allocated to the first PUSCH.

It should be understood that at least one time slot (or it can be understood as at least one time slot included in the time slot set) is located in the multiple time slots to which the first PUSCH is allocated.

Among them, at least one time slot is determined by the terminal device (or a chip in the terminal device, etc.) according to the second time slot. The second time slot is the time slot where the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetitions) overlaps with the first PUCCH. It can be understood that the terminal device determines at least one time slot using the second time slot as a reference time slot.

The following describes the implementation process of the terminal device determining at least one time slot based on the second time slot through the following possible examples.

Example 1: The terminal device may use N consecutive time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated as at least one time slot. Optionally, the second time slot may be included in the consecutive N time slots, so at least one time slot may also include the second time slot, or the second time slot may not be included in the consecutive N time slots, so at least one time slot may not include the second time slot.

Optionally, after determining the second time slot, the terminal device can use the second time slot as a reference time slot, determine N consecutive time slots starting from the second time slot from the multiple time slots allocated to the first PUSCH, and can use the N consecutive time slots as at least one time slot, or can also store the N consecutive time slots in (or add to) a time slot set.

For the value of N, in a possible implementation, the terminal device can determine the value of N according to the number of repetitions of the first UCI indicated by the network device (for example, the number of repetitions of the first UCI is M). For details, see the following description of the terminal device determining the value of N according to the number of repetitions of the first UCI indicated by the network device. The implementation process of determining N based on the number of repetitions of the first UCI is not described in detail here. In another possible implementation manner, the terminal device can also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmission in N consecutive time slots starting from the second time slot. In this way, by repeatedly multiplexing the first UCI, the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), and there is a partial overlap between the first PUSCH and the first PUCCH (abbreviated as PUCCH in Figure 6a), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 6a is a schematic diagram of a first UCI repetition multiplexing provided in Example 1 of the present application. As shown in Figure 6a, taking the example of a terminal device determining the value of N according to the number of repetitions of the first UCI indicated by the network device, it is assumed that the terminal device determines the value of N to be 3 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device may first determine three consecutive time slots starting from time slot 2 (i.e., time slot 2, time slot 3, and time slot 4) among the four time slots allocated with PUSCH repetition type A. Afterwards, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmission on time slot 2, the PUSCH transmission on time slot 3, and the PUSCH transmission on time slot 4 (it can be understood that the first UCI is multiplexed on three PUSCH transmissions, or it can also be understood that the multiplexing of the first UCI is repeated three times). For example, time slot 0, time slot 2, time slot 3, and time slot 4 illustrated in FIGS. 6a to 6f may be one of the downlink time slot D, the time slot X including only SBFD symbols, or the uplink time slot U, for example, time slot 0 is the downlink time slot D, time slot 1, time slot 2, and time slot 3 are all time slot X including only SBFD symbols, and time slot 4 is the uplink time slot U.

Example 2: The terminal device can use k time slots that meet the fourth condition from the consecutive N time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated as at least one time slot. The fourth condition is: only SBFD symbols are included (or it can be understood that non-SBFD symbols are not included) or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols (or it can be understood that non-SBFD symbols are not included). In other words, the terminal device can determine that the at least one time slot is k time slots that meet the following one (which can be understood as any one of the following) from the consecutive N time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated: only SBFD symbols are included or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols. Wherein, k≤N, N, k are integers greater than or equal to 1.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the first UCI indicated by the network device. For details, please refer to the implementation process of the terminal device determining N based on the number of repetitions of the first UCI indicated by the network device below, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmissions on k time slots that meet the fourth condition (such as only including SBFD symbols or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols) in the consecutive N time slots starting from the second time slot. In this way, by repeatedly multiplexing the first UCI on k PUSCH transmissions that are only allocated SBFD symbols, the flexibility of PUSCH scheduling can be improved, and the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), and there is a partial overlap between the first PUSCH and the first PUCCH (abbreviated as PUCCH in Figure 6b), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 6b is another schematic diagram of first UCI repetition multiplexing provided in Example 1 of the present application. As shown in Figure 6b, taking the example of the terminal device determining the value of N according to the number of repetitions of the first UCI indicated by the network device, it is assumed that the terminal device determines the value of N as 3 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device may first determine the three consecutive time slots (i.e., time slot 2, time slot 3, and time slot 4) starting from time slot 2 among the four time slots to which PUSCH repetition type A is allocated. Afterwards, the terminal device may select k time slots that meet the fourth condition from time slot 2, time slot 3, and time slot 4, for example, two time slots meet the fourth condition, i.e., time slot 2 and time slot 3. In other words, for time slot 2 to meet the fourth condition, it can be understood that time slot 2 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 2 only include SBFD symbols. For time slot 3 to meet the fourth condition, it can be understood that time slot 3 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 only include SBFD symbols. Then, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmission on time slot 2 and on the PUSCH transmission on time slot 3 (it can be understood that the first UCI is multiplexed on two PUSCH transmissions, or it can also be understood that the multiplexing of the first UCI is repeated twice).

Example 3: The terminal device may allocate N consecutive time slots starting from the second time slot among the multiple time slots allocated to the first PUSCH that meet the fourth condition. The time slot of the first PUSCH is used as at least one time slot. In other words, the terminal device can determine that the at least one time slot is the N consecutive time slots starting from the second time slot in the multiple time slots to which the first PUSCH is allocated, which meet one of the following conditions (which can be understood as any one of the following conditions): only SBFD symbols are included or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols. Optionally, the second time slot may be included in the N consecutive time slots that meet the fourth condition, so at least one time slot may also include the second time slot, or the second time slot may not be included in the N consecutive time slots that meet the fourth condition, so at least one time slot may also not include the second time slot.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the first UCI indicated by the network device. For details, please refer to the implementation process of the terminal device determining N based on the number of repetitions of the first UCI indicated by the network device below, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmissions in N consecutive time slots starting from the second time slot that satisfy the fourth condition (such as only including SBFD symbols or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols). In this way, by repeatedly multiplexing the first UCI on N consecutive PUSCH transmissions that are only allocated SBFD symbols, the flexibility of PUSCH scheduling can be improved, and the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), and there is a partial overlap between the first PUSCH and the first PUCCH (abbreviated as PUCCH in Figure 6c), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 6c is another schematic diagram of first UCI repetition multiplexing provided in Example 1 of the present application. As shown in Figure 6c, taking the example of a terminal device determining the value of N according to the number of repetitions of the first UCI indicated by the network device, it is assumed that the terminal device determines the value of N to be 2 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device can determine two consecutive time slots starting from time slot 2 that meet the fourth condition among the four time slots to which PUSCH repetition type A is allocated, such as time slot 3 and time slot 4. In other words, for time slot 3 to meet the fourth condition, it can be understood that time slot 3 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 only include SBFD symbols. For time slot 4 to meet the fourth condition, it can be understood that time slot 4 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 4 only include SBFD symbols. Then, the terminal device can repeatedly multiplex the first UCI on the PUSCH transmission on time slot 3 and the PUSCH transmission on time slot 4 (it can be understood that the first UCI is multiplexed on 2 PUSCH transmissions, or it can also be understood that the multiplexing of the first UCI is repeated twice).

For example, in another example, the terminal device may also determine that the N consecutive time slots starting from time slot 2 that meet the fourth condition are time slot 2 and time slot 3 among the four time slots to which PUSCH repetition type A is allocated. At this time, the value of N is also 2. In other words, for time slot 2 to meet the fourth condition, it can be understood that time slot 2 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 2 only include SBFD symbols. For time slot 3 to meet the fourth condition, it can be understood that time slot 3 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 only include SBFD symbols. Then, the terminal device may repeatedly multiplex the first UCI on the PUSCH transmission on time slot 2 and on the PUSCH transmission on time slot 3 (it can be understood that the first UCI is multiplexed on 2 PUSCH transmissions, or it can also be understood that the multiplexing of the first UCI is repeated 2 times).

In another example, the terminal device may also determine that the N consecutive time slots starting from time slot 2 that meet the fourth condition are time slot 2, time slot 3, and time slot 4 among the four time slots to which PUSCH repetition type A is allocated. At this time, the value of N is 3. In other words, for time slot 2 to meet the fourth condition, it can be understood that time slot 2 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 2 only include SBFD symbols. For time slot 3 to meet the fourth condition, it can be understood that time slot 3 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 only include SBFD symbols. For time slot 4 to meet the fourth condition, it can be understood that time slot 4 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 4 only include SBFD symbols. Then, the terminal device can repeatedly multiplex the first UCI on the PUSCH transmission on time slot 2, the PUSCH transmission on time slot 3, and the PUSCH transmission on time slot 4 (it can be understood that the first UCI is multiplexed on 3 PUSCH transmissions, or it can also be understood that the multiplexing of the first UCI is repeated 3 times).

In the case where the first PUSCH and the first PUCCH overlap in the time domain, compared to the existing scheme of multiplexing the first UCI on the PUSCH transmission in the overlapping time slot or multiplexing the first UCI on the actual repetition where repetition occurs, the implementation method 1 in the above-mentioned scheme 2 repeatedly multiplexes the first UCI on the PUSCH transmission in multiple time slots, which can be understood as repeatedly multiplexing the first UCI multiple times. This can improve the reliability of the first UCI multiplexing, thereby ensuring the reliability of the first UCI transmission. In addition, the implementation method 1 in the above-mentioned scheme 2 can also repeatedly multiplex the first UCI on k PUSCH transmissions that are only assigned SBFD symbols (or it can be understood that the symbols assigned to each PUSCH transmission in the k PUSCH transmissions only include SBFD symbols), which can improve the reliability of the PUSCH. Flexibility in scheduling.

Implementation method 2: When the first PUSCH is PUSCH repetition type B, the terminal device may multiplex the first UCI on at least one actual repetition (one or more actual repetitions (for example, at least two actual repetitions)) of the multiple actual repetitions included in the first PUSCH.

It can be understood that the first UCI is multiplexed on at least one actual repetition among multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B), it can be understood that the first UCI is carried on at least one actual repetition among multiple actual repetitions included in the first PUSCH, or it can be understood that the first UCI is sent on at least one actual repetition among multiple actual repetitions included in the first PUSCH.

It should be understood that at least one actual repetition (or it can be understood as at least one actual repetition included in the actual repetition set) is located among the multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B).

Among them, at least one actual repetition is determined by the terminal device (or a chip in the terminal device, etc.) according to the second actual repetition. The second actual repetition is the first actual repetition in the first PUSCH (such as PUSCH repetition type B) that overlaps with the first PUCCH in the time domain and has a number of symbols allocated greater than 1. It can be understood that the terminal device determines at least one actual repetition using the second actual repetition as a reference time slot.

The following describes the implementation process of the terminal device determining at least one actual repetition according to the second actual repetition through the following possible examples.

Example 1: The terminal device may use N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. Optionally, the second actual repetition may be included in the N consecutive actual repetitions, so at least one actual repetition may also include the second actual repetition, or the second actual repetition may not be included in the N consecutive actual repetitions, so at least one actual repetition may also not include the second actual repetition.

Optionally, after determining the second actual repetition, the terminal device may use the second actual repetition as a reference actual repetition, determine N consecutive actual repetitions starting from the second actual repetition from the multiple actual repetitions included in the first PUSCH, and may use the N consecutive actual repetitions as at least one actual repetition, or may store the N consecutive actual repetitions in (or add to) an actual repetition set.

Optionally, in a possible implementation, the terminal device may also take q actual repetitions satisfying the third condition from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. Wherein, q≤N, q is an integer greater than or equal to 1. In another possible implementation, the terminal device may also take N consecutive actual repetitions satisfying the third condition from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the first UCI indicated by the network device. For details, please refer to the implementation process of the terminal device determining N based on the number of repetitions of the first UCI indicated by the network device below, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on N consecutive actual repetitions starting from the second actual repetition. In this way, by repeatedly multiplexing the first UCI, the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (abbreviated as PUCCH in FIG. 6d) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. FIG6d is another schematic diagram of first UCI repetition multiplexing provided in Embodiment 1 of the present application. As shown in FIG6d , taking actual repetition 3 as the second actual repetition as an example, and taking the case where the terminal device determines the value of N according to the number of repetitions of the first UCI indicated by the network device as an example, it is assumed that the terminal device determines the value of N as 5 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device may first determine the 5 consecutive actual repetitions starting from actual repetition 3 (i.e., actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7) among the 7 actual repetitions included in PUSCH repetition type B. Afterwards, the terminal device may repetition multiplex the first UCI on actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7 (it can be understood that the first UCI is multiplexed on 5 actual repetitions, or it can also be understood that the multiplexing of the first UCI is repeated 5 times).

As an example, it is assumed that the terminal device determines the value of N according to the number of repetitions of the first UCI indicated by the network device. The terminal device determines that the value of N is 4 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device may also determine four consecutive actual repetitions starting from actual repetition 3 (such as actual repetition 3, actual repetition 4, actual repetition 5, and actual repetition 6) among the seven actual repetitions included in PUSCH repetition type B. Afterwards, the terminal device may multiplex the first UCI repetition on actual repetition 3, actual repetition 4, actual repetition 5, and actual repetition 6 (it can be understood that the first UCI is multiplexed on four actual repetitions, or it can also be understood that the multiplexing of the first UCI is repeated four times).

As another example, let's continue to take the example that the terminal device determines that the value of N is 5 according to the number of repetitions of the first UCI indicated by the network device. The terminal device can also determine 3 actual repetitions that meet the third condition (such as actual repetition 3, actual repetition 5, and actual repetition 6) from the 7 actual repetitions included in PUSCH repetition type B. After that, the terminal device can repeat multiplexing the first UCI on actual repetition 3, actual repetition 5, and actual repetition 6 (it can be understood that the first UCI is multiplexed on 3 actual repetitions, or it can also be understood that the multiplexing of the first UCI is repeated 3 times).

Example 2: The terminal device may take the p actual repetitions that meet the fifth condition and the third condition (that is, both the third condition and the fifth condition are met) from the consecutive N actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. The fifth condition is: only SBFD symbols are allocated (or it can be understood that non-SBFD symbols are not included). In other words, the terminal device can determine that the at least one actual repetition is the p actual repetitions that meet the following two conditions from the consecutive N actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH: only SBFD symbols are allocated, and the number of allocated symbols is greater than 1. Wherein, p≤N, p is an integer greater than or equal to 1. Optionally, the second actual repetition may be included in the consecutive N actual repetitions, so at least one actual repetition may also include the second actual repetition, or the second actual repetition may not be included in the consecutive N actual repetitions, so at least one actual repetition may also not include the second actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the first UCI indicated by the network device. For details, please refer to the implementation process of the terminal device determining N based on the number of repetitions of the first UCI indicated by the network device below, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on p actual repetitions that meet the fifth condition and the third condition among the consecutive N actual repetitions starting from the second actual repetition. In this way, by repeatedly multiplexing the first UCI, the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission. In addition, by repeatedly multiplexing the first UCI on multiple actual repetitions that meet the fifth condition or meet the fifth condition and the third condition, the flexibility of PUSCH scheduling can be improved, and the reliability of the first UCI multiplexing can be improved.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (abbreviated as PUCCH in FIG. 6e) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. FIG6e is another schematic diagram of first UCI repetition multiplexing provided in Embodiment 1 of the present application. As shown in FIG6e , the actual repetition 3 is continued to be taken as the second actual repetition as an example, and the terminal device determines the value of N as 5 according to the number of repetitions of the first UCI indicated by the network device as an example. The terminal device may first determine 5 consecutive actual repetitions starting from the actual repetition 3 among the 7 actual repetitions included in PUSCH repetition type B (such as actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7). Afterwards, the terminal device may determine p actual repetitions that meet the fifth condition and the third condition among the 5 consecutive actual repetitions, for example, there are 3 actual repetitions that meet the third condition and the fifth condition, such as actual repetition 3, actual repetition 5, and actual repetition 7. For actual repetition 3 to meet the fifth condition and the third condition, it can be understood that actual repetition 3 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 5 to meet the fifth condition and the third condition, it can be understood that actual repetition 5 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 7 satisfying the fifth condition and the third condition, it can be understood that actual repetition 7 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. Then, the terminal device can repeatedly multiplex the first UCI on actual repetition 3, actual repetition 5, and actual repetition 7 (it can be understood that the first UCI is multiplexed on 3 actual repetitions, or it can also be understood that the multiplexing of the first UCI is repeated 3 times).

Example 3: The terminal device may take N consecutive actual repetitions satisfying the fifth condition and the third condition from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. In other words, the terminal device may determine that the at least one actual repetition is N consecutive actual repetitions satisfying the following two conditions from the second actual repetition among the multiple actual repetitions included in the first PUSCH: Only SBFD symbols are allocated, and the number of allocated symbols is greater than 1. Optionally, N consecutive actual repetitions that satisfy the fifth condition and the third condition may include the second actual repetition, so at least one actual repetition may also include the second actual repetition, or N consecutive actual repetitions that satisfy the fifth condition and the third condition may not include the second actual repetition, so at least one actual repetition may also not include the second actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the first UCI indicated by the network device. For details, please refer to the implementation process of the terminal device determining N based on the number of repetitions of the first UCI indicated by the network device below, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, when the first PUSCH overlaps with the first PUCCH in the time domain, the terminal device may repeatedly multiplex the first UCI on N consecutive actual repetitions starting from the second actual repetition that satisfy the fifth condition and the third condition. In this way, by repeatedly multiplexing the first UCI, the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission. In addition, by repeatedly multiplexing the first UCI on multiple consecutive actual repetitions that satisfy the fifth condition or satisfy the fifth condition and the third condition, the flexibility of PUSCH scheduling can be improved, and the reliability of the first UCI multiplexing can be improved.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, the first PUSCH partially overlaps with the first PUCCH (abbreviated as PUCCH in FIG. 6f) (for example, actual repetition 3 and actual repetition 4 both overlap with the first PUCCH in the time domain), and the time slot where the partial overlap occurs is time slot 2, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. FIG6f is another schematic diagram of first UCI repetition multiplexing provided in Embodiment 1 of the present application. As shown in FIG6f, taking actual repetition 3 as the second actual repetition as an example, and taking the terminal device determining the value of N according to the number of repetitions of the first UCI indicated by the network device as an example, it is assumed that the terminal device determines the value of N as 3 according to the number of repetitions M of the first UCI indicated by the network device. The terminal device may first determine three consecutive actual repetitions starting from actual repetition 3 that meet the fifth condition and the third condition among the seven actual repetitions included in PUSCH repetition type B, such as actual repetition 3, actual repetition 4, and actual repetition 5. For actual repetition 3 that meets the fifth condition and the third condition, it can be understood that actual repetition 3 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 4 that meets the fifth condition and the third condition, it can be understood that actual repetition 4 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 5 that meets the fifth condition and the third condition, it can be understood that actual repetition 5 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. Then, the terminal device may repeatedly multiplex the first UCI on actual repetition 3, actual repetition 4, and actual repetition 5 (it can be understood that the first UCI is multiplexed on 3 actual repetitions, or it can also be understood that the multiplexing of the first UCI is repeated 3 times).

In the case where the first PUSCH and the first PUCCH overlap in the time domain, compared with the existing scheme of multiplexing the first UCI on the PUSCH transmission in the overlapping time slot or multiplexing the first UCI on the actual repetition where repetition occurs, the implementation method 1 in the above scheme 2 is to multiplex the first UCI repeatedly on multiple actual repetitions, which can be understood as multiplexing the first UCI repeatedly multiple times, so that the reliability of the first UCI multiplexing can be improved, thereby ensuring the reliability of the first UCI transmission. In addition, the implementation method 1 in the above scheme 2 can also improve the flexibility of PUSCH scheduling by repeatedly multiplexing the first UCI on multiple actual repetitions that are only allocated SBFD symbols or only allocated SBFD symbols and the number of allocated symbols is greater than 1.

In an embodiment of the present application, the first UCI may include HARQ-ACK and CSI, or the first UCI may also include only CSI. It should be understood that in some scenarios, considering that HARQ-ACK has high requirements for timing, if the multiplexing of HARQ-ACK is postponed or repeated, errors may occur or performance may be greatly reduced. However, CSI does not have high requirements for timing, and postponing or repeating the multiplexing of CSI will not cause errors or significant performance reduction. Therefore, in these scenarios, only the multiplexing of CSI may be postponed or repeated, that is, the first UCI includes only CSI. In addition, in some scenarios, the requirements of HARQ-ACK for timing may not be considered. In this case, the multiplexing of HARQ-ACK and CSI may be postponed or repeated, that is, the first UCI includes HARQ-ACK and CSI.

In addition, the following describes the implementation process of the terminal device determining N according to the number of repetitions of the first UCI indicated by the network device (for example, the number of repetitions of the first UCI is M) through the following possible implementation methods.

Method 1: When the first UCI is multiplexed on the first PUSCH transmission located in at least one time slot in the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition), if the first number of consecutive time slots starting from the second time slot in the multiple time slots allocated to the first PUSCH is greater than or equal to the number of repetitions of the first UCI, the terminal device can use the number of repetitions of the first UCI as the value of N. If the first number of time slots is less than the number of repetitions of the first UCI, the terminal device may use the first number as the value of N. Thereafter, the terminal device may determine which of the at least one time slots are based on the second time slot and in combination with N.

For example, the number of repetitions of the first UCI indicated by the network device is 4. When the terminal device determines (or counts) that the number of consecutive time slots starting from the second time slot in the multiple time slots to which the first PUSCH is allocated (for example, 5) is greater than the number of repetitions of the first UCI 4, the terminal device can use the number of repetitions of the first UCI 4 as the value of N. When the terminal device determines that the number of consecutive time slots starting from the second time slot in the multiple time slots to which the first PUSCH is allocated (for example, 3) is less than the number of repetitions of the first UCI 4, the terminal device can use the number of consecutive time slots starting from the second time slot in the multiple time slots as the value of N.

Mode 2: When the first UCI is multiplexed on the first PUSCH transmission located in at least one time slot in the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition), if the third number of consecutive time slots satisfying the fourth condition (such as only including SBFD symbols or the symbols allocated to the first PUSCH in the time slot only including any one of the SBFD symbols) starting from the second time slot among the multiple time slots allocated to the first PUSCH is greater than or equal to the number of repetitions of the first UCI, the terminal device may use the number of repetitions of the first UCI as the value of N. If the third number of consecutive time slots satisfying the fourth condition starting from the second time slot among the multiple time slots allocated to the first PUSCH is less than the number of repetitions of the first UCI, the terminal device may use the third number as the value of N. Afterwards, the terminal device may determine which of the at least one time slots are based on the second time slot and in combination with N.

For example, let's continue to take the case where the number of repetitions of the first UCI indicated by the network device is 4. When the terminal device determines that the number of consecutive time slots that meet the fourth condition starting from the second time slot among the multiple time slots to which the first PUSCH is allocated (for example, 6) is greater than the number of repetitions of the first UCI 4, the terminal device can use the number of repetitions of the first UCI 4 as the value of N. When the terminal device determines that the number of consecutive time slots that meet the fourth condition starting from the second time slot among the multiple time slots to which the first PUSCH is allocated (for example, 2) is less than the number of repetitions of the first UCI 4, the terminal device can use the number of consecutive time slots that meet the fourth condition starting from the second time slot among the multiple time slots as the value of N.

Mode 3: When the first UCI is multiplexed on at least one actual repetition in the first PUSCH (such as PUSCH repetition type B), if the second number of consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH is greater than or equal to the number of repetitions of the first UCI, the terminal device may use the number of repetitions of the first UCI as the value of N. If the second number of consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH is less than the number of repetitions of the first UCI, the terminal device may use the second number as the value of N.

For example, let's continue to take the case where the number of repetitions of the first UCI indicated by the network device is 4. When the number of consecutive multiple actual repetitions starting from the second actual repetition in the multiple actual repetitions included in the first PUSCH (for example, 5) is greater than the number of repetitions of the first UCI 4, the terminal device can use the number of repetitions of the first UCI 4 as the value of N. When the number of consecutive multiple actual repetitions starting from the second actual repetition in the multiple actual repetitions included in the first PUSCH (for example, 3) is less than the number of repetitions of the first UCI 4, the terminal device can use the number of consecutive multiple actual repetitions starting from the second actual repetition in the multiple actual repetitions 3 as the value of N.

Mode 4: When the first UCI is multiplexed on at least one actual repetition in the first PUSCH (such as PUSCH repetition type B), if the fourth number of actual repetitions that meet the fifth condition (such as only SBFD symbols are allocated) and the third condition (such as the number of allocated symbols is greater than 1) starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH is greater than or equal to the number of repetitions of the first UCI, the terminal device may use the number of repetitions of the first UCI as the value of N. If the fourth number of actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH is less than the number of repetitions of the first UCI, the terminal device may use the fourth number as the value of N.

For example, let's continue to take the case where the number of repetitions of the first UCI indicated by the network device is 4. When the number of actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH (for example, 6) is greater than the number of repetitions of the first UCI 4, the terminal device can use the number of repetitions of the first UCI 4 as the value of N. When the number of actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH (for example, 2) is less than the number of repetitions of the first UCI 4, the terminal device can use the number of actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition among the multiple actual repetitions 2 as the value of N.

The following describes the implementation process of a terminal device obtaining the number of repetitions of the first UCI from a network device through the following possible implementation methods.

Implementation method 1: The network device sends a first RRC message (or a first RRC signaling). Accordingly, the terminal device receives the first RRC message from the network device. The first RRC message may include the number of repetitions of the first UCI (such as M). The number of repetitions of the first UCI is included in at least one candidate number of the first UCI.

For example, the at least one candidate number of the first UCI may include one or more of the following values: 2, 4, 8, 10, 12, 16, or 32.

For example, the network device may carry the number of repetitions of the first UCI (such as 2) in the first RRC message. After receiving the first RRC message from the network device, the device may obtain the number of repetitions of the first UCI (for example, 2) from the first RRC message.

Implementation method 2: The network device sends a second RRC message. Accordingly, the terminal device receives the second RRC message from the network device. The second RRC message may include a first table (or a first array), and the first table may include s rows. The value of each row in the s rows included in the first table is one of at least one candidate number of the first UCI, which can be understood as a candidate number selected from at least one candidate number of the first UCI. For example, the first table may be an s*1 table, or an s*t table, where t is used to represent the column of the first table, and t is an integer greater than or equal to 2. Afterwards, the network device sends indication information. Accordingly, the terminal device receives indication information from the network device. The indication information may be used to indicate the value of the i-th row in the first table as the number of repetitions of the first UCI. For example, taking the first table as an s*1 table, assuming that s is 3, and assuming that the value of the first row in the first table is 2, the value of the second row is 8, and the value of the third row is 10, the indication information indicates that the value 8 of the second row in the first table is the number of repetitions of the first UCI. For example, the indication information may be DCI.

It can be seen from the above steps 301 to 302 that when the first PUSCH overlaps with the first PUCCH in the time domain, when the first PUSCH is PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition, by multiplexing the first UCI on the PUSCH transmission on the non-SBFD symbols in the first PUSCH, or when the first PUSCH is PUSCH repetition type B, by multiplexing the first UCI on the actual repetition in the first PUSCH that is not allocated SBFD symbols and the number of allocated symbols is greater than 1, effective multiplexing of the first UCI can be achieved, which helps to improve the reliability of the first UCI multiplexing, thereby ensuring the reliability of the first UCI transmission. In addition, when the first PUSCH is one of PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition, the reliability of the first UCI multiplexing may be improved by repetitively multiplexing the first UCI on PUSCH transmissions located on multiple time slots in the first PUSCH, thereby ensuring the reliability of the first UCI transmission. When the first PUSCH is PUSCH repetition type B, the reliability of the first UCI multiplexing is improved by repetitively multiplexing the first UCI on multiple actual repetitions in the first PUSCH, thereby ensuring the reliability of the first UCI transmission.

[Example 2]

FIG7 exemplarily shows a flow chart of a communication method provided in Embodiment 2 of the present application. The method is applicable to the communication system architecture illustrated in FIG2. The method flow may be implemented by data interaction between multiple communication devices (such as a first communication device and a second communication device). Optionally, the first communication device may be a terminal device or a component (such as a chip, a chip system or a circuit, etc.) that can support the terminal device to implement the functions required by the method, or other devices with the functions of the terminal device, or other functional modules with the functions of the communication method, and the second communication device may be a network device or a component (such as a chip, a chip system or a circuit, etc.) that can support the network device to implement the functions required by the method, or other devices with the functions of the network device, or other functional modules with the functions of the communication method. Exemplarily, the terminal device may be a terminal device 100 as illustrated in FIG2, and the network device may be a network device 200 as illustrated in FIG2. It can be understood that the application scenario applicable to the communication method illustrated in FIG7 is: the network device sends a message (such as a third message) for scheduling the terminal device to send a first transmission block and an aperiodic CSI, and the aperiodic CSI is multiplexed (or carried) on the first PUSCH, and the first transmission block is also carried on the first PUSCH. In order to facilitate the introduction of the technical solution provided in the second embodiment of the present application, the following takes the first communication device as a terminal device and the second communication device as a network device as an example to introduce the process of implementing the communication method by data interaction between the first communication device and the second communication device. As shown in FIG7 , the method includes:

Step 701: The network device sends the third information. Correspondingly, the terminal device receives the third information from the network device.

Optionally, in an embodiment of the present application, if the terminal device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the received information comes from; if the network device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the sent information is sent to.

Optionally, if the network device is a distributed architecture, for example, the network device includes a CU and/or a DU, or includes one or more of a CU-CP, a CU-UP, or a DU, when the network device includes a DU, the network device sends the third information, specifically, the DU included in the network device sends the third information. Optionally, the network device including the DU may also include a CU; or, the network device including the DU may also include a CU-CP and/or a CU-UP.

For example, the third information may be DCI or the like.

The third information may be used to instruct the terminal device to send the first transport block and the aperiodic CSI, and the first transport block and the aperiodic CSI are carried on the first PUSCH. It should be understood that the aperiodic CSI is a form (or type) of UCI.

Optionally, the first PUSCH may refer to a PUSCH to which multiple time slots are allocated, or the first PUSCH may refer to a PUSCH including multiple actual repetitions. For example, the first PUSCH may be one of PUSCH repetition type A, PUSCH repetition type B, TBoMS PUSCH, or TBoMS PUSCH repetition. PUSCH repetition can be jointly simplified as: TBoMS PUSCH w/or w/o repetition. For example, when the first PUSCH is PUSCH repetition type A or TBoMS PUSCH w/or w/o repetition, the first PUSCH can be allocated multiple time slots. When the first PUSCH is PUSCH repetition type B, the first PUSCH can include multiple actual repetitions. It should be understood that the multiple actual repetitions included in PUSCH repetition type B can be located in one time slot, or can also be located in multiple time slots, and the embodiments of the present application are not limited to this.

Step 702: The terminal device sends a first transmission block and aperiodic CSI. Accordingly, the network device receives the first transmission block and aperiodic CSI from the terminal device.

In an embodiment of the present application, after obtaining the third information from the network device, the terminal device can multiplex (or can be called a carrier) the non-periodic CSI on the first PUSCH for transmission (or sending). However, since the non-periodic CSI multiplexing on the first PUSCH has the problem of low transmission reliability (for example, when the non-periodic CSI is multiplexed on the PUSCH transmission located on the SBFD symbol, the channel environment on the SBFD symbol is different from the channel environment on the uplink symbol (for example, the network device will be affected by the CLI of other network devices on the SBFD symbol), resulting in poor reliability of non-periodic CSI transmission), in order to solve this problem, the terminal device can, but is not limited to, adopt the following possible solutions to achieve effective multiplexing of non-periodic CSI on the first PUSCH, thereby improving the reliability (or stability) of non-periodic CSI transmission.

Solution 1: The terminal device postpones the reuse of the non-periodic CSI.

The following describes several possible implementations of the terminal device postponing the multiplexing of non-periodic CSI.

Implementation method 1: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition), the terminal device may multiplex the non-periodic CSI on the first PUSCH transmission in the first time slot in the first PUSCH.

It can be understood that the non-periodic CSI is multiplexed on the first PUSCH transmission in the first time slot in the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition), and it can be understood that the non-periodic CSI is carried on the first PUSCH transmission in the first time slot in the first PUSCH, or it can be understood that the non-periodic CSI is sent (or transmitted) on the first PUSCH transmission in the first time slot in the first PUSCH.

It should be understood that the first time slot is one of a plurality of time slots to which the first PUSCH is allocated.

Several possible ways of determining the first time slot are introduced below.

Method 1: The terminal device may use the time slot that meets the first condition among the multiple time slots allocated to the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition) as the first time slot.

Optionally, the relevant content of the first condition involved in step 702 can refer to the relevant content of the first condition involved in the above step 302, which will not be repeated here.

Method 2: The terminal device can determine the first time slot according to the second time slot. The second time slot is the first time slot of multiple time slots allocated to the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition).

The following describes the implementation process of the terminal device determining the first time slot based on the second time slot through the following possible examples.

Example 1: When the second time slot satisfies the first condition (i.e., the second time slot does not include an SBFD symbol, or the symbol allocated to the first PUSCH in the second time slot does not include an SBFD symbol), the terminal device may use the second time slot as (or determine it to be) the first time slot. In other words, when the second time slot satisfies the first condition, the terminal device determines that the first time slot is the second time slot.

For example, when the first time slot in the first PUSCH (ie, the second time slot) satisfies the first condition (or can be understood as the first time slot in the first PUSCH does not include an SBFD symbol), the terminal device can multiplex non-periodic CSI on the PUSCH transmission in the first time slot in the first PUSCH.

Exemplarily, taking the first PUSCH as PUSCH repetition type A as an example, assume that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated to PUSCH repetition type A, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 8a is a schematic diagram of non-periodic CSI multiplexing provided in Example 2 of the present application. As shown in Figure 8a, when time slot 1 does not include a SBFD symbol or the symbol allocated to the first PUSCH in time slot 1 does not include a SBFD symbol, the terminal device can multiplex the non-periodic CSI on the PUSCH transmission on time slot 1. For example, time slot 0, time slot 2, time slot 3, and time slot 4 shown in Figures 8a to 8e can be respectively one of the downlink time slot D, the time slot X that only includes SBFD symbols, or the uplink time slot U. For example, time slot 0 is the downlink time slot D, time slot 1, time slot 2, and time slot 3 are all time slot X that only includes SBFD symbols, and time slot 4 is the uplink time slot U.

Example 2: When the second time slot does not meet the first condition (i.e., the second time slot includes an SBFD symbol, or the second time slot is allocated to the first In other words, the terminal device can determine that the first time slot is the first time slot that satisfies the first condition and is located after the second time slot among the multiple time slots to which the first PUSCH is allocated and satisfies one of the following conditions (which can be understood as any one of the following conditions): does not include SBFD symbols or the symbols allocated to the first PUSCH in the time slot do not include SBFD symbols (or it can be called that the symbols allocated to the first PUSCH in the time slot do not include SBFD symbols).

For example, when the first time slot in the first PUSCH (i.e., the second time slot) does not meet the first condition (or it can be understood that the first time slot in the first PUSCH includes an SBFD symbol), the terminal device can postpone the multiplexing of the non-periodic CSI to the PUSCH transmission on the non-SBFD symbol (such as the PUSCH transmission on the first time slot that meets the first condition and is located after the second time slot in the multiple time slots allocated to the first PUSCH).

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, assume that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated to PUSCH repetition type A, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 8b is another non-periodic CSI multiplexing schematic diagram provided in Example 2 of the present application. As shown in Figure 8b, when time slot 1 includes an SBFD symbol or the symbol allocated to the first PUSCH in time slot 1 includes an SBFD symbol, the terminal device can first determine the first time slot that meets the first condition after time slot 1, such as time slot 3. In other words, time slot 3 is the first time slot after time slot 1 that does not include an SBFD symbol, or time slot 3 is the first time slot after time slot 1 in which the symbol allocated to the first PUSCH does not include an SBFD symbol. Afterwards, the terminal device can postpone the multiplexing of the non-periodic CSI to the PUSCH transmission on time slot 3.

Example three: When the second time slot does not meet the first condition, and there is no time slot meeting the first condition after the second time slot in the multiple time slots allocated to the first PUSCH (that is, there is no time slot meeting one of the following items (which can be understood as any one of the following items) after the second time slot in the multiple time slots allocated to the first PUSCH: does not include an SBFD symbol or the symbols allocated to the first PUSCH in the time slot do not include an SBFD symbol), the terminal device may use the second time slot as the first time slot.

For example, when the first time slot (i.e., the second time slot) in the first PUSCH does not meet the first condition, and there is no time slot meeting the first condition after the second time slot in the multiple time slots allocated to the first PUSCH, the terminal device can multiplex the non-periodic CSI on the PUSCH transmission in the first time slot in the first PUSCH.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated to PUSCH repetition type A, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. When time slot 1 includes an SBFD symbol or the symbol allocated to the first PUSCH in time slot 1 includes an SBFD symbol, and time slot 3 and time slot 4 located after time slot 1 are both time slots that do not meet the first condition, the terminal device can multiplex the non-periodic CSI on the PUSCH transmission on time slot 1. For time slot 3 not meeting the first condition, it can be understood that time slot 3 includes an SBFD symbol, or the symbol allocated to the first PUSCH in time slot 3 includes an SBFD symbol. For time slot 4 not satisfying the first condition, it can be understood that time slot 4 includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 4 include SBFD symbols.

Optionally, the above-mentioned method 1 and method 2 can be implemented separately as a solution, or can be combined and implemented as a solution.

Compared with the existing scheme of multiplexing the non-periodic CSI on the PUSCH transmission on the first time slot of the first PUSCH, the implementation method 1 in the above scheme 1, when the first time slot of the first PUSCH includes the SBFD symbol, by postponing the multiplexing of the non-periodic CSI to the PUSCH transmission on the non-SBFD symbol, can improve the effectiveness and reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, when the first time slot of the first PUSCH does not include the SBFD symbol, the implementation method 1 in the above scheme 1 can also multiplex the non-periodic CSI on the PUSCH transmission on the first time slot of the first PUSCH, which can also ensure that the transmission of the non-periodic CSI is not affected, thereby ensuring the reliability of the non-periodic CSI transmission.

Implementation method 2: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition), the terminal device can multiplex the non-periodic CSI on the first transmission opportunity in the first PUSCH.

It can be understood that the non-periodic CSI is multiplexed on the first transmission opportunity in the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of the TBoMS PUSCH repetitions), which can be understood as the non-periodic CSI being carried on the first transmission opportunity in the first PUSCH, or it can be understood that the non-periodic CSI is sent (or transmitted) on the first transmission opportunity in the first PUSCH.

It should be understood that the first transmission opportunity is one of the multiple transmission opportunities to which the first PUSCH is allocated, that is, it can be understood that the first transmission opportunity is located in the multiple transmission opportunities.

Several possible ways of determining the first transmission opportunity are introduced below.

Method 1: The terminal device may use the transmission timing that meets the first condition among the multiple transmission timings allocated to the first PUSCH (such as PUSCH repetition type A or TBoMS PUSCH or one of TBoMS PUSCH repetition) as the first transmission timing.

Optionally, the relevant content of the first condition involved in step 702 can refer to the relevant content of the first condition involved in the above step 302, which will not be repeated here.

Method 2: The terminal device may determine the first transmission timing according to the second transmission timing. The second transmission timing is the first transmission timing in the first PUSCH (such as one of PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition). It can be understood that the terminal device determines the first transmission timing by using the second transmission timing as a reference transmission timing.

Optionally, the implementation process of the terminal device determining the first transmission timing according to the second transmission timing in the implementation method 2 of Scheme 1 of step 702 can refer to the implementation process of the terminal device determining the first time slot according to the second time slot in the implementation method 1 of Scheme 1 of step 702, and will not be repeated here.

Optionally, the above-mentioned method 1 and method 2 can be implemented separately as a solution, or can be combined and implemented as a solution.

Compared with the existing scheme of multiplexing the non-periodic CSI on the first transmission opportunity of the first PUSCH, the second implementation method of the above scheme 1, when the first transmission opportunity of the first PUSCH includes the SBFD symbol, postpones the multiplexing of the non-periodic CSI to the transmission opportunity that does not include the SBFD symbol, thereby improving the effectiveness and reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, when the first transmission opportunity of the first PUSCH does not include the SBFD symbol, the second implementation method of the above scheme 1 can also multiplex the non-periodic CSI on the first transmission opportunity of the first PUSCH, thereby ensuring that the transmission of the non-periodic CSI is not affected, thereby ensuring the reliability of the non-periodic CSI transmission.

Implementation method three: When the first PUSCH is PUSCH repetition type B, the terminal device may multiplex the non-periodic CSI on the first actual repetition in the first PUSCH.

It can be understood that the non-periodic CSI is multiplexed on the first actual repetition in the first PUSCH (such as PUSCH repetition type B), which can be understood as the non-periodic CSI is carried on the first actual repetition in the first PUSCH, or it can be understood as the non-periodic CSI is sent on the first actual repetition in the first PUSCH.

It should be understood that the first actual repetition is one of multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B).

Several possible ways of determining the first actual repetition are described below.

Method 1: The terminal device may use the actual repetition that meets the second condition and/or the third condition among multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B) as the first actual repetition.

For example, the second condition is: no SBFD symbols are allocated, and the third condition is: the number of allocated symbols is greater than 1. For the first actual repetition to satisfy the second condition and/or the third condition, it can be understood that the first actual repetition is not allocated SBFD symbols, or the number of symbols allocated to the first actual repetition is greater than 1, or the first actual repetition is allocated SBFD symbols and (and) the number of allocated symbols is greater than 1.

Exemplarily, taking the first actual repetition as an actual repetition that satisfies the second condition among multiple actual repetitions included in the first PUSCH as an example, the first actual repetition is an actual repetition that is not allocated SBFD symbols among the multiple actual repetitions included in the first PUSCH, that is, it can be understood that the first actual repetition is an actual repetition that is only allocated to uplink symbols and/or flexible symbols among the multiple actual repetitions.

Mode 2: The terminal device may determine the first actual repetition based on the second actual repetition. The second actual repetition is the first actual repetition among multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B). It can be understood that the terminal device determines the first actual repetition based on the second actual repetition as a reference actual repetition.

The following describes the implementation process of the terminal device determining the first actual repetition according to the second actual repetition through the following possible examples.

Example 1: When the second actual repetition satisfies the second condition (i.e., the second actual repetition is not allocated SBFD symbols) and the third condition (i.e., the number of symbols allocated to the second actual repetition is greater than 1, or it can be understood that the number of symbols allocated to the second actual repetition in the time slot where the second actual repetition is located is greater than 1), the terminal device can use the second actual repetition (i.e., the first actual repetition among the multiple actual repetitions included in the first PUSCH) as the first actual repetition. In other words, when the second actual repetition satisfies the second condition and the third condition, the terminal device determines that the second actual repetition is the second actual repetition.

For example, when the first actual repetition (ie, the second actual repetition) among the multiple actual repetitions included in the first PUSCH is not allocated SBFD symbol, and when the number of symbols allocated to the first actual repetition of multiple actual repetitions included in the first PUSCH is greater than 1, the terminal device can multiplex the non-periodic CSI on the second actual repetition that is not allocated SBFD symbol.

Exemplarily, taking the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 8c is another non-periodic CSI multiplexing schematic diagram provided in the second embodiment of the present application. As shown in Figure 8c, when actual repetition 1 is not allocated SBFD symbols (that is, the symbols allocated to actual repetition 1 in slot 1 do not include SBFD symbols), and the number of symbols allocated to actual repetition 1 is greater than 1 (that is, the number of symbols allocated to actual repetition 1 in slot 1 is greater than 1), the terminal device can multiplex non-periodic CSI on actual repetition 1.

Example 2: When the second actual repetition does not satisfy the second condition (i.e., the second actual repetition is allocated SBFD symbols) or the second actual repetition does not satisfy the third condition (i.e., the number of symbols allocated to the second actual repetition is less than or equal to 1), the terminal device may use the first actual repetition that satisfies the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH as the first actual repetition. In other words, the terminal device may determine that the first actual repetition is the first actual repetition that satisfies the following two conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH: not allocated SBFD symbols, and the number of symbols allocated is greater than 1.

For example, when the first actual repetition (i.e., the second actual repetition) of multiple actual repetitions included in the first PUSCH is allocated SBFD symbols, or the number of symbols allocated to the first actual repetition of multiple actual repetitions included in the first PUSCH is less than or equal to 1, the terminal device can postpone the multiplexing of non-periodic CSI to the first actual repetition of the multiple actual repetitions included in the first PUSCH that is located after the second actual repetition and meets the second and third conditions.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, it is assumed that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and it is assumed that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), such as actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 8d is another non-periodic CSI multiplexing schematic diagram provided in the second embodiment of the present application. As shown in FIG8d , when actual repetition 1 is allocated SBFD symbols (i.e., symbols allocated to actual repetition 1 in slot 1 include SBFD symbols) or the number of symbols allocated to actual repetition 1 is less than or equal to 1 (i.e., the number of symbols allocated to actual repetition 1 in slot 1 is less than or equal to 1), the terminal device may first determine the first actual repetition after actual repetition 1 that satisfies the second and third conditions, such as actual repetition 2. In other words, actual repetition 2 is the first actual repetition after actual repetition 1 that satisfies the second and third conditions. Afterwards, the terminal device may postpone the aperiodic CSI multiplexing to actual repetition 2.

Example three: When the second actual repetition does not satisfy the second condition or the second actual repetition does not satisfy the third condition, and there is no actual repetition that satisfies the second and third conditions after the second actual repetition in the multiple actual repetitions included in the first PUSCH (that is, there is no actual repetition that satisfies the following two conditions after the second actual repetition in the multiple actual repetitions included in the first PUSCH: no SBFD symbols are allocated, and the number of allocated symbols is greater than 1), the terminal device may use the second actual repetition (that is, the first actual repetition among the multiple actual repetitions included in the first PUSCH) as the first actual repetition.

For example, when the first actual repetition (i.e., the second actual repetition) among the multiple actual repetitions included in the first PUSCH is allocated SBFD symbols or the number of symbols allocated to the first actual repetition among the multiple actual repetitions included in the first PUSCH is less than or equal to 1, and there is no actual repetition that meets the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH, the terminal device can multiplex the non-periodic CSI on the first actual repetition among the multiple actual repetitions included in the first PUSCH.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3, and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, time slot 4 is located in time slot 3. Afterwards. When actual repetition 1 is allocated SBFD symbols (i.e., symbols allocated to actual repetition 1 in time slot 1 include SBFD symbols) or the number of symbols allocated to actual repetition 1 is less than or equal to 1 (i.e., the number of symbols allocated to actual repetition 1 in time slot 1 is less than or equal to 1), and actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7 located after actual repetition 1 do not meet the second condition and the third condition, the terminal device may multiplex the non-periodic CSI on actual repetition 1.

Example 4: When the second actual repetition does not satisfy the second condition or the second actual repetition does not satisfy the third condition, and there is no actual repetition satisfying the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH, the terminal device may take the first actual repetition that satisfies the third condition (i.e., the number of symbols allocated is greater than 1) after the second actual repetition among the multiple actual repetitions included in the first PUSCH as the first actual repetition. In other words, the terminal device may determine that the first actual repetition is the first actual repetition that is located after the second actual repetition among the multiple actual repetitions included in the first PUSCH and the number of symbols allocated is greater than 1.

For example, when the first actual repetition (i.e., the second actual repetition) among the multiple actual repetitions included in the first PUSCH is allocated an SBFD symbol or the number of symbols allocated to the first actual repetition among the multiple actual repetitions included in the first PUSCH is less than or equal to 1, and there is no actual repetition that meets the second and third conditions after the second actual repetition among the multiple actual repetitions included in the first PUSCH, the terminal device can postpone the multiplexing of the non-periodic CSI to the first actual repetition that meets the third condition and is located after the second actual repetition among the multiple actual repetitions included in the first PUSCH.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 8e is another non-periodic CSI multiplexing schematic diagram provided in the second embodiment of the present application. As shown in FIG8e, when actual repetition 1 is allocated SBFD symbols (i.e., symbols allocated to actual repetition 1 in slot 1 include SBFD symbols) or the number of symbols allocated to actual repetition 1 is less than or equal to 1 (i.e., the number of symbols allocated to actual repetition 1 in slot 1 is less than or equal to 1), and actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6, and actual repetition 7 after actual repetition 1 do not meet the second condition and the third condition, the terminal device may first determine the first actual repetition after actual repetition 1 that meets the third condition, such as actual repetition 3. In other words, actual repetition 3 is the first actual repetition after actual repetition 1 that meets the third condition. Afterwards, the terminal device may postpone the non-periodic CSI multiplexing to actual repetition 3.

Compared with the existing scheme of multiplexing the non-periodic CSI on the first actual repetition (such as the second actual repetition) of the multiple actual repetitions included in the first PUSCH, when the second actual repetition is allocated with SBFD symbols or the number of symbols allocated to the second actual repetition is less than or equal to 1, by postponing the multiplexing of the non-periodic CSI to the actual repetition that is not allocated with SBFD symbols and the number of symbols allocated is greater than 1 (such as the first actual repetition that is not allocated with SBFD symbols and the number of symbols allocated is greater than 1 after the second actual repetition), the effectiveness and reliability of the non-periodic CSI multiplexing can be improved, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, when the second actual repetition is not allocated with SBFD symbols and the number of symbols allocated is greater than 1, the non-periodic CSI can also be multiplexed on the second actual repetition, thereby ensuring that the transmission of the non-periodic CSI is not affected, thereby ensuring the reliability of the non-periodic CSI transmission.

Solution 2: The terminal device repeats the multiplexing of the non-periodic CSI (or it can be understood that the terminal device repeatedly multiplexes the non-periodic CSI multiple times, for example, the terminal device can repeatedly multiplex the non-periodic CSI on PUSCH transmissions in multiple time slots in the first PUSCH, or can also repeatedly multiplex the non-periodic CSI on multiple transmission opportunities in the first PUSCH, or can also repeatedly multiplex the non-periodic CSI on multiple actual repetitions in the first PUSCH).

The following describes the multiplexing of repeated non-periodic CSI by a terminal device through the following possible implementation methods.

Implementation method 1: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition), the terminal device may multiplex the non-periodic CSI on the first PUSCH transmission located in at least one time slot (one or more time slots (for example, at least two time slots)) among the multiple time slots allocated to the first PUSCH.

It can be understood that the non-periodic CSI is multiplexed on the first PUSCH transmission located in at least one time slot among the multiple time slots to which the first PUSCH is allocated. It can be understood that the non-periodic CSI is carried on the first PUSCH transmission located in at least one time slot among the multiple time slots to which the first PUSCH is allocated, and the non-periodic CSI is sent on the first PUSCH transmission located in at least one time slot among the multiple time slots to which the first PUSCH is allocated.

It should be understood that at least one time slot (or at least one time slot included in the time slot set) is located in the multiple time slots to which the first PUSCH is allocated. in a time slot.

The at least one time slot is determined by the terminal device (or a chip in the terminal device, etc.) according to the second time slot. The second time slot is the first time slot in the first PUSCH. It can be understood that the terminal device determines at least one time slot using the second time slot as a reference time slot.

The following describes the implementation process of the terminal device determining at least one time slot based on the second time slot through the following possible examples.

Example 1: The terminal device may use N consecutive time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated as at least one time slot. Optionally, the second time slot may be included in the consecutive N time slots, so at least one time slot may also include the second time slot, or the second time slot may not be included in the consecutive N time slots, so at least one time slot may not include the second time slot.

Optionally, after determining the second time slot, the terminal device can use the second time slot as a reference time slot, determine N consecutive time slots starting from the second time slot from the multiple time slots allocated to the first PUSCH, and can use the N consecutive time slots as at least one time slot, or can also store the N consecutive time slots in (or add to) a time slot set.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device (for example, the number of repetitions of the non-periodic CSI is M). For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the first embodiment above, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may re-multiplex the aperiodic CSI on the PUSCH transmission in N consecutive time slots starting from the second time slot. In this way, the reliability of the aperiodic CSI multiplexing can be improved by re-multiplexing the aperiodic CSI, thereby ensuring the reliability of the aperiodic CSI transmission.

Exemplarily, taking the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated to PUSCH repetition type A, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 9a is a schematic diagram of non-periodic CSI repetition multiplexing provided in Example 2 of the present application. As shown in Figure 9a, taking the example of the terminal device determining the value of N according to the number of repetitions of the non-periodic CSI indicated by the network device, it is assumed that the terminal device determines the value of N to be 4 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device may first determine four consecutive time slots (e.g., time slot 1, time slot 2, time slot 3, and time slot 4) starting from time slot 1 among the four time slots allocated with PUSCH repetition type A. Afterwards, the terminal device may repeatedly multiplex the non-periodic CSI on the PUSCH transmission on time slot 1, the PUSCH transmission on time slot 2, the PUSCH transmission on time slot 3, and the PUSCH transmission on time slot 4 (it can be understood that the non-periodic CSI is multiplexed on four PUSCH transmissions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated four times). For example, time slot 0, time slot 2, time slot 3, and time slot 4 shown in FIG. 9a to FIG. 9f may be one of the downlink time slot D, the time slot X including only SBFD symbols, or the uplink time slot U, for example, time slot 0 is the downlink time slot D, time slot 1, time slot 2, and time slot 3 are all time slot X including only SBFD symbols, and time slot 4 is the uplink time slot U.

Example 2: The terminal device can use k time slots that meet the fourth condition in the N consecutive time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated as at least one time slot. The fourth condition is: only SBFD symbols are included (or it can be understood that non-SBFD symbols are not included) or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols (or it can be understood that non-SBFD symbols are not included). In other words, the terminal device can determine that the at least one time slot is k time slots that meet the following one (which can be understood as any one of the following) in the N consecutive time slots starting from the second time slot among the multiple time slots to which the first PUSCH is allocated: only SBFD symbols are included or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols. Wherein, k≤N, N, k are integers greater than or equal to 1. Optionally, the second time slot may be included in the N consecutive time slots, so at least one time slot may also include the second time slot, or the second time slot may not be included in the N consecutive time slots, so at least one time slot may not include the second time slot.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device. For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the above embodiment 1, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may repeatedly multiplex the non-periodic CSI on the PUSCH transmissions on k time slots that meet the fourth condition (such as only including SBFD symbols or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols) in the consecutive N time slots starting from the second time slot. In this way, by repeatedly multiplexing the non-periodic CSI on the k PUSCH transmissions that are only allocated SBFD symbols, the flexibility of PUSCH scheduling can be improved, and the reliability of non-periodic CSI multiplexing can be improved, thereby ensuring the reliability of non-periodic CSI transmission.

For example, continuing to take the first PUSCH as PUSCH repetition type A as an example, assuming that PUSCH repetition type A is Four time slots are allocated (for example, time slot 1, time slot 2, time slot 3, and time slot 4). Each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated for PUSCH repetition type A, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 9b is another schematic diagram of non-periodic CSI repetition multiplexing provided in Example 2 of the present application. As shown in Figure 9b, taking the example of a terminal device determining the value of N according to the number of repetitions of the non-periodic CSI indicated by the network device, it is assumed that the terminal device determines the value of N to be 4 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device can first determine the four consecutive time slots (for example, time slot 1, time slot 2, time slot 3, and time slot 4) starting from time slot 1 among the four time slots allocated for PUSCH repetition type A. Afterwards, the terminal device can select k time slots that meet the fourth condition from time slot 1, time slot 2, time slot 3 and time slot 4. For example, there are 2 time slots that meet the fourth condition, such as time slot 1 and time slot 2. In other words, for time slot 1 to meet the fourth condition, it can be understood that time slot 1 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 1 only include SBFD symbols. For time slot 2 to meet the fourth condition, it can be understood that time slot 2 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 2 only include SBFD symbols. Then, the terminal device can repeatedly multiplex the non-periodic CSI on the PUSCH transmission on time slot 1 and the PUSCH transmission on time slot 2 (it can be understood that the non-periodic CSI is multiplexed on 2 PUSCH transmissions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated twice).

Example three: The terminal device may use N consecutive time slots that meet the fourth condition starting from the second time slot among the multiple time slots to which the first PUSCH is allocated as at least one time slot. In other words, the terminal device may determine that the at least one time slot is N consecutive time slots that meet one of the following (which can be understood as any one of the following) starting from the second time slot among the multiple time slots to which the first PUSCH is allocated: only SBFD symbols or the symbols allocated to the first PUSCH in the time slot only include SBFD symbols. Optionally, the second time slot may be included in the N consecutive time slots that meet the fourth condition, so at least one time slot may also include the second time slot, or the second time slot may not be included in the N consecutive time slots that meet the fourth condition, so at least one time slot may not include the second time slot.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device. For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the above embodiment 1, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may repeatedly multiplex the non-periodic CSI on the PUSCH transmissions in N consecutive time slots starting from the second time slot that satisfy the fourth condition (such as only including SBFD symbols or the symbols allocated to the first PUSCH in the time slot only including SBFD symbols). In this way, by repeatedly multiplexing the non-periodic CSI on N consecutive PUSCH transmissions that are only allocated SBFD symbols, the flexibility of PUSCH scheduling can be improved, and the reliability of non-periodic CSI multiplexing can be improved, thereby ensuring the reliability of non-periodic CSI transmission.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type A as an example, it is assumed that PUSCH repetition type A is allocated 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4). Among them, each time slot corresponds to a PUSCH (or can be called PUSCH transmission), time slot 1 is the first time slot of multiple time slots allocated to PUSCH repetition type A, time slot 1 is before time slot 2, time slot 3 is after time slot 2, and time slot 4 is after time slot 3. Figure 9c is another schematic diagram of non-periodic CSI repetition multiplexing provided in Example 2 of the present application. As shown in Figure 9c, taking the example of the terminal device determining the value of N according to the number of repetitions of the non-periodic CSI indicated by the network device, it is assumed that the terminal device determines the value of N to be 3 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device can determine three consecutive time slots starting from time slot 1 that meet the fourth condition among the four time slots allocated for PUSCH repetition type A, such as time slot 1, time slot 2, and time slot 3. In other words, for time slot 1 to meet the fourth condition, it can be understood that time slot 1 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 1 only include SBFD symbols. For time slot 2 to meet the fourth condition, it can be understood that time slot 2 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 2 only include SBFD symbols. For time slot 3 to meet the fourth condition, it can be understood that time slot 3 only includes SBFD symbols, or the symbols allocated to the first PUSCH in time slot 3 only include SBFD symbols. Then, the terminal device can repeatedly multiplex the non-periodic CSI on the PUSCH transmission on time slot 1, the PUSCH transmission on time slot 2, and the PUSCH transmission on time slot 3 (it can be understood that the non-periodic CSI is multiplexed on 3 PUSCH transmissions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated 3 times).

Compared with the existing scheme of multiplexing the non-periodic CSI on the PUSCH transmission on the first time slot in the first PUSCH, or multiplexing the non-periodic CSI on the first actual repetition in the first PUSCH, or multiplexing the non-periodic CSI on the first transmission opportunity in the first PUSCH, the implementation method 1 in the above scheme 2 repeatedly multiplexes the non-periodic CSI on the PUSCH transmission on multiple time slots, which can be understood as repeatedly multiplexing the non-periodic CSI multiple times, thereby improving the reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, the implementation method 1 in the above scheme 2 can also improve the flexibility of PUSCH scheduling by repeatedly multiplexing the non-periodic CSI on k PUSCH transmissions that are only allocated SBFD symbols.

Implementation method 2: When the first PUSCH is PUSCH repetition type A or TBoMS PUSCH (or TBoMS PUSCH repetition type A When the first PUSCH is allocated (multiple), the terminal device can multiplex the non-periodic CSI on at least one transmission opportunity (one or more transmission opportunities (such as at least two transmission opportunities)) among the multiple transmission opportunities allocated to the first PUSCH.

It can be understood that the non-periodic CSI multiplexing is located on at least one transmission opportunity among the multiple transmission opportunities allocated to the first PUSCH. It can be understood that the non-periodic CSI carrying is located on at least one transmission opportunity among the multiple transmission opportunities allocated to the first PUSCH. The non-periodic CSI is sent on at least one transmission opportunity among the multiple transmission opportunities allocated to the first PUSCH.

It should be understood that at least one transmission opportunity (or it can be understood as at least one transmission opportunity included in the transmission opportunity set) is located in the multiple transmission opportunities to which the first PUSCH is allocated.

Among them, at least one transmission opportunity is determined by the terminal device (or a chip in the terminal device, etc.) according to the second transmission opportunity. The second transmission opportunity is the first transmission opportunity in the first PUSCH. It can be understood that the terminal device determines at least one transmission opportunity using the second transmission opportunity as a reference transmission opportunity.

Optionally, the implementation process of the terminal device determining at least one transmission timing according to the second transmission timing in implementation method 2 of scheme 2 of step 702 can refer to the implementation process of the terminal device determining at least one time slot according to the second time slot in implementation method 1 of scheme 2 of step 702, and will not be repeated here.

Compared with the existing scheme of multiplexing the non-periodic CSI on the PUSCH transmission on the first time slot in the first PUSCH, or multiplexing the non-periodic CSI on the first actual repetition in the first PUSCH, or multiplexing the non-periodic CSI on the first transmission opportunity in the first PUSCH, the second implementation method in the above scheme 2 can improve the reliability of the non-periodic CSI multiplexing by repeatedly multiplexing the non-periodic CSI on multiple transmission opportunities, which can be understood as repeatedly multiplexing the non-periodic CSI multiple times, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, the second implementation method in the above scheme 2 can also improve the flexibility of PUSCH scheduling by repeatedly multiplexing the non-periodic CSI on k transmission opportunities that only include SBFD symbols.

Implementation method three: When the first PUSCH is PUSCH repetition type B, the terminal device may multiplex the non-periodic CSI on at least one actual repetition among the multiple actual repetitions included in the first PUSCH.

It can be understood that the non-periodic CSI is multiplexed on at least one actual repetition among the multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B), it can be understood that the non-periodic CSI is carried on at least one actual repetition among the multiple actual repetitions included in the first PUSCH, or it can be understood that the non-periodic CSI is sent on at least one actual repetition among the multiple actual repetitions included in the first PUSCH.

It should be understood that at least one actual repetition (or it can be understood as at least one actual repetition included in the actual repetition set) is located among the multiple actual repetitions included in the first PUSCH (such as PUSCH repetition type B).

The at least one actual repetition is determined by the terminal device (or a chip in the terminal device, etc.) according to the second actual repetition. The second actual repetition is the first actual repetition among the multiple actual repetitions included in the first PUSCH. It can be understood that the terminal device determines the at least one actual repetition using the second actual repetition as a reference time slot.

The following describes the implementation process of the terminal device determining at least one actual repetition according to the second actual repetition through the following possible examples.

Example 1: The terminal device may use N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. Optionally, the second actual repetition may be included in the N consecutive actual repetitions, so at least one actual repetition may also include the second actual repetition, or the second actual repetition may not be included in the N consecutive actual repetitions, so at least one actual repetition may also not include the second actual repetition.

Optionally, after determining the second actual repetition, the terminal device may use the second actual repetition as a reference actual repetition, determine N consecutive actual repetitions starting from the second actual repetition from the multiple actual repetitions included in the first PUSCH, and may use the N consecutive actual repetitions as at least one actual repetition, or may store the N consecutive actual repetitions in (or add to) an actual repetition set.

Optionally, in a possible implementation, the terminal device may also take q actual repetitions satisfying the third condition from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. Wherein, q≤N, q is an integer greater than or equal to 1. In another possible implementation, the terminal device may also take N consecutive actual repetitions satisfying the third condition from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device. For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the above embodiment 1, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may repeatedly multiplex the aperiodic CSI on N consecutive actual repetitions starting from the second actual repetition. In this way, the reliability of the aperiodic CSI multiplexing can be improved by repeatedly multiplexing the aperiodic CSI, thereby ensuring the reliability of the aperiodic CSI transmission. Reliability of loss.

Exemplarily, taking the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 9d is another schematic diagram of non-periodic CSI repetition multiplexing provided in Embodiment 2 of the present application. As shown in FIG9d , taking the example of the terminal device determining the value of N according to the number of repetitions of the non-periodic CSI indicated by the network device, it is assumed that the terminal device determines the value of N to be 4 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device may first determine the 4 consecutive actual repetitions starting from actual repetition 1 (i.e., actual repetition 1, actual repetition 2, actual repetition 3, and actual repetition 4) among the 7 actual repetitions included in PUSCH repetition type B. Afterwards, the terminal device may repetitively multiplex the non-periodic CSI on actual repetition 1, actual repetition 2, actual repetition 3, and actual repetition 4 (it can be understood that the non-periodic CSI is multiplexed on 4 actual repetitions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated 4 times).

Example 2: The terminal device may take p actual repetitions that meet the fifth condition and the third condition from N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. The fifth condition is: only SBFD symbols are allocated. In other words, the terminal device can determine that the at least one actual repetition is p actual repetitions that meet the following two conditions from N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH: only SBFD symbols are allocated, and the number of allocated symbols is greater than 1. Wherein, p≤N, p is an integer greater than or equal to 1. Optionally, the second actual repetition may be included in N consecutive actual repetitions, so at least one actual repetition may also include the second actual repetition, or the second actual repetition may not be included in N consecutive actual repetitions, so at least one actual repetition may also not include the second actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device. For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the above embodiment 1, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may repeatedly multiplex the non-periodic CSI on p actual repetitions that meet the fifth condition and the third condition among the consecutive N actual repetitions starting from the second actual repetition. In this way, by repeatedly multiplexing the non-periodic CSI, the reliability of the non-periodic CSI multiplexing can be improved, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, by repeatedly multiplexing the non-periodic CSI on multiple actual repetitions that meet the fifth condition or meet the fifth condition and meet the third condition, the flexibility of PUSCH scheduling can be improved, and the reliability of the non-periodic CSI multiplexing can be improved.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, assuming that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and assuming that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition of the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 9e is another schematic diagram of non-periodic CSI repetition multiplexing provided in Embodiment 2 of the present application. As shown in FIG. 9e, the example in which the terminal device determines that the value of N is 4 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device may first determine the 4 consecutive actual repetitions starting from the actual repetition 1 (such as actual repetition 1, actual repetition 2, actual repetition 3, and actual repetition 4) among the 7 actual repetitions included in PUSCH repetition type B. Afterwards, the terminal device may determine the p actual repetitions that meet the fifth condition and the third condition among the 4 consecutive actual repetitions, for example, there are 2 actual repetitions that meet the fifth condition and the third condition, such as actual repetition 1 and actual repetition 3. For actual repetition 1 to meet the fifth condition and the third condition, it can be understood that actual repetition 1 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 3 to meet the fifth condition and the third condition, it can be understood that actual repetition 3 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. Then, the terminal device may multiplex the non-periodic CSI repetitions on actual repetition 1 and actual repetition 3 (it can be understood that the non-periodic CSI is multiplexed on 2 actual repetitions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated 2 times).

Example 3: The terminal device may use N consecutive actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH as at least one actual repetition. In other words, the terminal device may determine the at least one actual repetition. The repetition is N consecutive actual repetitions starting from the second actual repetition among the multiple actual repetitions included in the first PUSCH that meet the following two items: only SBFD symbols are allocated, and the number of allocated symbols is greater than 1. Optionally, the second actual repetition may be included in the N consecutive actual repetitions that meet the fifth condition and the third condition, so at least one actual repetition may also include the second actual repetition, or the second actual repetition may not be included in the N consecutive actual repetitions that meet the fifth condition and the third condition, so at least one actual repetition may also not include the second actual repetition.

Regarding the value of N, in one possible implementation, the terminal device may determine the value of N based on the number of repetitions of the non-periodic CSI indicated by the network device. For details, please refer to the implementation process in which the terminal device determines N based on the number of repetitions of the first UCI indicated by the network device in the above embodiment 1, which will not be repeated here. In another possible implementation, the terminal device may also determine the value of N by itself according to actual needs.

For example, the terminal device may repeatedly multiplex the non-periodic CSI on N consecutive actual repetitions that meet the fifth condition and the third condition starting from the second actual repetition. In this way, by repeatedly multiplexing the non-periodic CSI, the reliability of the non-periodic CSI multiplexing can be improved, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, by repeatedly multiplexing the non-periodic CSI on multiple consecutive actual repetitions that meet the fifth condition or meet the fifth condition and meet the third condition, the flexibility of PUSCH scheduling can be improved, and the reliability of the non-periodic CSI multiplexing can be improved.

Exemplarily, continuing to take the first PUSCH as PUSCH repetition type B as an example, it is assumed that PUSCH repetition type B includes 7 actual repetitions (such as actual repetition 1, actual repetition 2, actual repetition 3, actual repetition 4, actual repetition 5, actual repetition 6 and actual repetition 7), and it is assumed that the 7 actual repetitions are located in 4 time slots (such as time slot 1, time slot 2, time slot 3 and time slot 4), for example, actual repetition 1 and actual repetition 2 are located in time slot 1, actual repetition 3 and actual repetition 4 are located in time slot 2, actual repetition 5 and actual repetition 6 are located in time slot 3, and actual repetition 7 is located in time slot 4. Among them, actual repetition 1 is the first actual repetition among the 7 actual repetitions included in PUSCH repetition type B, time slot 1 is located before time slot 2, time slot 3 is located after time slot 2, and time slot 4 is located after time slot 3. Figure 9f is another schematic diagram of non-periodic CSI repetition multiplexing provided in Embodiment 2 of the present application. As shown in FIG9f, taking the example that the terminal device determines the value of N according to the number of repetitions of the non-periodic CSI indicated by the network device, it is assumed that the terminal device determines the value of N to be 3 according to the number of repetitions of the non-periodic CSI indicated by the network device. The terminal device can first determine that the three consecutive actual repetitions starting from the actual repetition 1 meet the fifth condition and the third condition among the 7 actual repetitions included in PUSCH repetition type B, such as actual repetition 2, actual repetition 3, and actual repetition 4. For actual repetition 2, the fifth condition and the third condition are satisfied, which can be understood as that actual repetition 2 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 3, the fifth condition and the third condition are satisfied, which can be understood as that actual repetition 3 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. For actual repetition 4, the fifth condition and the third condition are satisfied, which can be understood as that actual repetition 4 is only allocated SBFD symbols and the number of allocated symbols is greater than 1. Then, the terminal device can multiplex the non-periodic CSI repetitions on actual repetition 2, actual repetition 3, and actual repetition 4 (it can be understood that the non-periodic CSI is multiplexed on 3 actual repetitions, or it can also be understood that the multiplexing of the non-periodic CSI is repeated 3 times).

Compared with the existing scheme of multiplexing the non-periodic CSI on the PUSCH transmission on the first time slot in the first PUSCH, or multiplexing the non-periodic CSI on the first actual repetition in the first PUSCH, or multiplexing the non-periodic CSI on the first transmission opportunity in the first PUSCH, the implementation method three in the above-mentioned scheme two repeatedly multiplexes the non-periodic CSI on multiple actual repetitions, which can be understood as repeatedly multiplexing the non-periodic CSI multiple times, thereby improving the reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, the implementation method three in the above-mentioned scheme two can also improve the flexibility of PUSCH scheduling by repeatedly multiplexing the non-periodic CSI on multiple actual repetitions that are only allocated SBFD symbols or only allocated SBFD symbols and the number of allocated symbols is greater than 1.

It can be seen from the above steps 701 to 702 that when the first PUSCH is one of PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition, by multiplexing the non-periodic CSI on the PUSCH transmission on the non-SBFD symbols in the first PUSCH, or when the first PUSCH is PUSCH repetition type B, by multiplexing the non-periodic CSI on the actual repetition of the first PUSCH that is not allocated SBFD symbols and the number of allocated symbols is greater than 1, effective multiplexing of the non-periodic CSI can be achieved, which helps to improve the reliability of the non-periodic CSI multiplexing, thereby ensuring the reliability of the non-periodic CSI transmission. In addition, when the first PUSCH is one of PUSCH repetition type A or TBoMS PUSCH or TBoMS PUSCH repetition, the reliability of the non-periodic CSI multiplexing can also be improved by repeatedly multiplexing the non-periodic CSI on the PUSCH transmission located on multiple time slots in the first PUSCH, thereby ensuring the reliability of the non-periodic CSI transmission. When the first PUSCH is PUSCH repetition type B, the reliability of non-periodic CSI multiplexing is improved by multiplexing the non-periodic CSI over multiple actual repetitions in the first PUSCH, thereby ensuring the reliability of non-periodic CSI transmission.
