Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. In the description of the present application, unless otherwise indicated, "/" means that the related objects are in a "or" relationship, for example, a/B may mean a or B, and "and/or" in the present application is merely an association relationship describing the related objects, for example, a and/or B may mean that there may be three relationships, for example, a and/or B, three cases where a exists alone, a and B exist together, and B exists alone, where a and B may be singular or plural. Also, in the description of the present application, unless otherwise indicated, "a plurality" means two or more than two. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (a, b, or c) of a, b, c, a-b, a-c, b-c, or a-b-c may be represented, wherein a, b, c may be single or plural. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, the following description is made before describing the solutions of the present application.

(1) In the present application, "indication" may include direct indication, indirect indication, explicit indication, implicit indication. When a certain indication information is described for indicating a, it can be understood that the indication information carries a, directly indicates a, or indirectly indicates a.

In the application, the information indicated by the indication information is called information to be indicated. In a specific implementation process, there are various ways to indicate the information to be indicated, for example, but not limited to, the information to be indicated may be directly indicated, such as the information to be indicated itself or an index of the information to be indicated. The information to be indicated can also be indicated indirectly by indicating other information, wherein the other information and the information to be indicated have an association relation. It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent. In addition, the information to be indicated can be sent together as a whole or can be divided into a plurality of pieces of sub-information to be sent separately, and the sending periods and/or sending occasions of the pieces of sub-information can be the same or different.

(2) In the present application, "transmit" and "receive" refer to the trend of signal transmission. For example, "sending information to XX" may be understood as the destination of the information being XX, and may include sending directly over the air, as well as sending indirectly over the air by other units or modules. "receiving information from YY" is understood to mean that the source of the information is YY, and may include receiving directly from YY over an air interface, or may include receiving indirectly from YY over an air interface from another unit or module. "send" may also be understood as "output" of the chip interface and "receive" may also be understood as "input" of the chip interface. In other words, the transmission and reception may be performed between devices, for example, between a network device and a terminal device, or may be performed within a device, for example, between components within a device, between modules, between chips, between software modules or between hardware modules through a bus, wiring or interface. Further, "transmitting," includes receiving and/or transmitting, unless specifically stated otherwise. For example, transmitting the signal may include receiving the signal and/or transmitting the signal.

(3) In the present application, information C is used for the determination of information D, including both information D being determined based on information C alone and information C and other information. In addition, the information C is used for determination of the information D, and a case of indirect determination is also possible, for example, the information D is determined based on the information E, and the information E is determined based on the information C.

(4) The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.

(5) In various embodiments of the application, where no special description or logic conflict exists, terms and/or descriptions between the various embodiments are consistent and may reference each other, and features of the various embodiments may be combined to form new embodiments based on their inherent logic.

(6) In the present application, "first" and "second" are merely for convenience of description, and are used for distinguishing objects, not for limiting the scope of the embodiments of the present application. Rather than to describe a sequence or order of features. It is to be understood that the objects so described may be interchanged under appropriate circumstances so as to enable description of aspects other than the embodiments of the application.

(7) In the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The architecture diagram of the mobile communication system shown in fig. 1 is a schematic diagram of the architecture diagram of a communication system 1000 to which the embodiment of the present application is applied. As shown in fig. 1, the communication system comprises a radio access network 100 and a core network 200, and optionally the communication system 1000 may further comprise the internet 300. The radio access network 100 may include at least one radio access network device (e.g., 110a and 110b in fig. 1) and may also include at least one terminal device (e.g., 120a-120j in fig. 1). The terminal device is connected to the radio access network device by radio means, e.g. the terminal device may be connected to the radio access network device via an air interface (AIR INTERFACE). The radio access network device is connected with the core network in a wireless or wired manner. The core network device and the radio access network device may be separate physical devices, or may integrate the functions of the core network device and the logic functions of the radio access network device on the same physical device, or may integrate the functions of part of the core network device and part of the radio access network device on one physical device. The terminal device and the radio access network device may be connected to each other by a wired or wireless method. In fig. 1, only schematic diagram is shown, and other network devices may be further included in the communication system, for example, a wireless relay device and a wireless backhaul device may also be included, which are not shown in fig. 1.

The radio access network device is an access device to which the terminal device accesses the communication system in a wireless manner. The radio access network device may be a base station (base station), an evolved NodeB (eNodeB), a transmission and reception point (TRANSMISS ION RECEPTION POINT, TRP), a gNB in a 5G mobile communication system, a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc., and in another possible scenario, a plurality of radio access network (radio access network, RAN) nodes cooperate to assist the terminal in implementing radio access, and different RAN nodes implement part of the functions of the base station, respectively. For example, the RAN node may be a Centralized Unit (CU), a Distributed Unit (DU), a CU-Control Plane (CP), a CU-User Plane (UP), or a Radio Unit (RU), etc. The CU and the DU may be provided separately or may be included in the same network element, e.g. in a baseband unit (BBU). RU may be included in a radio frequency device or unit, such as in a remote radio unit (remote radio uni t, RRU), an active antenna processing unit (ACTIVE ANTENNA uni, AAU), or a remote radio head (remote radio head, RRH).

In different systems, CUs (or CU-CP and CU-UP), DUs or RUs may also have different names, but the meaning will be understood by those skilled in the art. For example, in an open RAN (ora) system, a CU may also be referred to as an O-CU (open CU), a DU may also be referred to as an O-DU, a CU-CP may also be referred to as an O-CU-CP, a CU-UP may also be referred to as an O-CU-UP, and an RU may also be referred to as an O-RU. For convenience of description, the present application is described by taking CU, CU-CP, CU-UP, DU and RU as examples. Any unit of CU (or CU-CP, CU-UP), DU and RU in the present application may be implemented by a software module, a hardware module, or a combination of software and hardware modules. Embodiments of the application may be implemented by a DU or RU. The CU here performs the functions of the radio resource control protocol and the packet data convergence layer protocol (PACKET DATA convergence protocol, PDCP) of the base station, and may also perform the functions of the service data adaptation protocol (SERVICE DATA ADAPTAT ion protocol, SDAP), the DU performs the functions of the radio link control layer and the medium access control layer of the base station, and may also perform the functions of part of the physical layer or all of the physical layers, and for specific description of the above-mentioned protocol layers, reference may be made to the relevant technical specifications of the third generation partnership project (3rd generat ion partnership project,3GPP).

The radio access network device may be a macro base station (e.g. 110a in fig. 1), a micro base station or an indoor station (e.g. 110b in fig. 1), a relay node or a donor node, etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the wireless access network equipment. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the wireless access network equipment. For convenience of description, the network device is simply referred to as a radio access network device, and the base station is an example of the radio access network device.

The terminal device also has a wireless transceiving function, and can transmit signals to a base station or receive signals from the base station. The terminal device may also be referred to as a terminal, user Equipment (UE), mobile station, mobile terminal device, etc. The terminal device may be widely applied to various scenes, for example, environment IOT, device-to-device (D2D), vehicle-to-device (vehicle to everything, V2X) communication, machine-type communicat ion (MTC), virtual reality, augmented reality, industrial control, autopilot, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal equipment can be a mobile phone, a tablet personal computer, a computer with a wireless receiving and transmitting function, a wearable device, a vehicle, an unmanned aerial vehicle, a helicopter, an airplane, a ship, a robot, a mechanical arm, intelligent household equipment and the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

The base station and the terminal device may be fixed in location or may be movable. The base station and the terminal equipment can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted, on water surface, on aircraft, balloon and satellite. The embodiment of the application does not limit the application scenes of the base station and the terminal equipment.

The roles of base station and terminal device may be relative, e.g., helicopter or drone 120i in fig. 1 may be configured as a mobile base station, terminal device 120i being the base station for those terminal devices 120j that access radio access network 100 through 120i, but 120i being the terminal device for base station 110a, i.e., communication between 110a and 120i being via a wireless air interface protocol. Of course, communication between 110a and 120i may be performed via an interface protocol between base stations, and in this case, 120i is also a base station with respect to 110 a. Thus, both the base station and the terminal device may be collectively referred to as a communication apparatus, 110a and 110b in fig. 1 may be referred to as a communication apparatus having a base station function, and 120a-120j in fig. 1 may be referred to as a communication apparatus having a terminal device function.

Communication between the base station and the terminal equipment, between the base station and the base station, and between the terminal equipment and the terminal equipment can be performed through a licensed spectrum, communication can be performed through an unlicensed spectrum, communication can be performed through both the licensed spectrum and the unlicensed spectrum, communication can be performed through a spectrum below 6 gigahertz (GHz), communication can be performed through a spectrum above 6GHz, and communication can be performed through a spectrum below 6GHz and a spectrum above 6 GHz. The embodiment of the application does not limit the spectrum resources used by the wireless communication.

In the embodiment of the present application, the functions of the base station may be performed by a module (such as a chip) in the base station, or may be performed by a control subsystem including the functions of the base station. The control subsystem comprising the base station function can be a control center in the application scenarios of smart power grids, industrial control, intelligent transportation, smart cities and the like. The functions of the terminal device may be performed by a module (e.g., a chip or a modem) in the terminal device, or may be performed by an apparatus including the functions of the terminal device.

The network device provided by the embodiment of the present application may be, for example, 110a or 110b in fig. 1, and the terminal device provided by the embodiment of the present application may be, for example, any one of 120a to 120j in fig. 1.

The related functions of the network device or the terminal device according to the present application may be implemented by one device, or may be implemented by a plurality of devices together, or may be implemented by one or more functional modules in one device, or may be one or more chips, or may be a System On Chip (SOC) or a chip system, where the chip system may be formed by a chip, or may include a chip and other discrete devices, and embodiments of the present application are not limited in this regard.

It will be appreciated that the above described functionality may be either a network element in a hardware device, or a software functionality running on dedicated hardware, or a combination of hardware and software, or a virtualized functionality instantiated on a platform (e.g., a cloud platform).

For example, the related functions of the network device or the terminal device in the embodiment of the present application may be implemented by the communication apparatus 110 in fig. 2.

Fig. 2 shows a schematic structural diagram of one possible communication device 110. It will be appreciated that the communications apparatus 110 comprises means in the form of necessary, for example modules, units, elements, circuits, or interfaces, to be suitably configured together to implement the present solution. The communication device 110 may be a network device or a terminal device, or may be a component (e.g. a chip) in these devices, for implementing the method described in the method embodiments below. The communication device 110 includes one or more processors 111. The processor 111 may be a general purpose processor or a special purpose processor or the like. For example, a baseband processor, or a central processing unit. The baseband processor may be used to process communication protocols and communication data, and the central processor may be used to control a communication apparatus (e.g., a network device, a terminal device, or a chip, etc.), execute a software program, and process data of the software program.

Alternatively, in one design, the processor 111 may include a program 113 (sometimes also referred to as code or instructions), the program 113 may be executed on the processor 111 to cause the communication device 110 to perform the methods described in the embodiments below. In yet another possible design, communication device 110 includes circuitry (not shown in FIG. 2).

Optionally, the communication device 110 may include one or more memories 112, on which a program 114 (sometimes also referred to as code or instructions) is stored, the program 114 being executable on the processor 111 such that the communication device 110 performs the methods described in the method embodiments below.

Optionally, artificial intelligence (ART IFICIAL INTEL L IGENCE, AI) modules 117, 118 may be included in the processor 111 and/or memory 112, for implementing AI-related functions. The AI module may be implemented in software, hardware, or a combination of both. For example, the AI module may include a RAN Intelligent Controller (RIC) module. For example, the AI module may be a near real-time RIC or a non-real-time RIC.

Optionally, the processor 111 and/or the memory 112 may also have data stored therein. The processor and the memory may be provided separately or may be integrated.

Optionally, the communication device 110 may also include a transceiver 115 and/or an antenna 116. The processor 111 may also sometimes be referred to as a processing unit, controlling a communication device, such as a network device or a terminal device. The transceiver 115 may also be referred to as a transceiver unit, a transceiver circuit, a transceiver, or the like, for implementing the transceiver function of the communication device via the antenna 116.

Further, the constituent structure shown in fig. 2 does not constitute a limitation of the communication apparatus, and the communication apparatus may include more or less components than those shown in fig. 2, or may combine some components, or may be arranged in different components, in addition to those shown in fig. 2.

To support AI technology in a wireless network, AI nodes may also be introduced into the network.

Alternatively, the AI node may be deployed in one or more of the following locations in the communication system, such as a radio access network device, a terminal device, or a core network device, or the AI node may be deployed separately, e.g., in a location other than any of the above devices, such as a host or cloud server of an Over The Top (OTT) system. The AI node may communicate with other devices in the communication system, e.g., one or more of a network device, a terminal device, or a network element of a core network, etc.

It will be appreciated that the present application is not limited to the number of AI nodes. For example, when there are multiple AI nodes, the multiple AI nodes may be partitioned based on functionality, such as with different AI nodes being responsible for different functionality.

It is further understood that the AI node may be a separate device, or may be integrated into the same device to implement different functions, or may be a network element in a hardware device, or may be a software function running on dedicated hardware, or may be a virtualized function instantiated on a platform (e.g., a cloud platform), and the specific form of the AI node is not limited by the present application.

The AI node may be an AI network element or AI module.

Fig. 3 is a schematic diagram of one possible application framework in a communication system. As shown in fig. 3, network elements in the communication system are connected through interfaces (e.g., NG, xn, F1), or air interfaces. One or more AI modules (only 1 is shown in fig. 3 for clarity) are provided in one or more of these network element nodes, e.g. core network devices, access network nodes (RAN nodes), terminals or operation and maintenance management (operat ion administrat ion AND MAINTENANCE, OAM). The access network node may be a separate RAN node or may comprise a plurality of RAN nodes, e.g. including CUs and DUs. The CU and/or DU may also be provided with one or more AI modules. Optionally, a CU can also be split into CU-CP and CU-UP. One or more AI models are provided in the CU-CP and/or the CU-UP.

The AI module is used for realizing corresponding AI functions. AI modules deployed in different network elements may be the same or different. The model of the AI module is configured according to different parameters, and the AI module can realize different functions. The model of the AI module may be configured based on one or more parameters of a structural parameter (e.g., at least one of a number of layers of the neural network, a width of the neural network, a connection relationship between layers, a weight of the neuron, an activation function of the neuron, or a bias in the activation function), an input parameter (e.g., a type of input parameter and/or a dimension of the input parameter), or an output parameter (e.g., a type of output parameter and/or a dimension of the output parameter). The bias in the activation function may also be referred to as a bias of the neural network, among other things.

An AI module may have one or more models. A model can infer an output that includes a parameter or parameters. The learning process, training process, or reasoning process of the different models may be deployed in different nodes or devices, or may be deployed in the same node or device.

Fig. 4 is a schematic diagram of another possible application framework in a communication system. As shown in fig. 4, a RAN Intelligent Controller (RIC) is included in the communication system. For example, the RIC may be AI modules 117,118 shown in fig. 4 for implementing AI-related functions. The RICs include near-real-time RICs (near-REAL T IME RIC, near-RT RICs), and Non-real-time RICs (Non-REAL T IME RIC, non-RT RICs). The non-real-time RIC mainly processes non-real-time information, such as delay-insensitive data, which may be in the order of seconds. Real-time RIC primarily handles near real-time information, such as data that is relatively time sensitive, with time delays on the order of tens of milliseconds.

The near real-time RIC is used for model training and reasoning. For example, for training AI models with which reasoning is performed. Near real-time RIC may obtain information on the network side and/or the terminal side from RAN nodes (e.g., CU-CP, CU-UP, DU and/or RU) and/or terminals. This information may be used as training data or as reasoning data. Alternatively, the near real-time RIC may submit the inference results to the RAN node and/or terminal. Optionally, the inference results may be interacted between the CU and DU, and/or between the DU and RU. For example, near real-time RIC delivers the reasoning results to the DU, which sends it to the RU.

The non-real-time RIC is also used for model training and reasoning. For example, for training AI models, with which reasoning is performed. The non-real-time RIC may obtain information on the network side and/or the terminal side from RAN nodes (e.g., CUs, CU-CPs, CU-UPs, DUs, and/or RUs) and/or terminals. The information may be as training data or as inference data, and the inference results may be submitted to the RAN node and/or terminal. Alternatively, the inference results may be interacted between the CU and the DU, and/or between the DU and the RU, e.g., the non-real-time RIC submits the inference results to the DU, which is sent to the RU by the DU.

The near real-time RIC and the non real-time RIC may also be separately configured as a network element. Alternatively, the near real-time RIC, non-real-time RIC may be part of other devices, e.g., near real-time RIC is provided in a RAN node (e.g., CU, DU), while non-real-time RIC is provided in OAM, a cloud server, a core network device, or other network device.

Embodiments of the present application may be applied to a 5G New Radio (NR) wireless communication system to achieve high data rates and low delays by using a large bandwidth. In a time division duplex system, as shown in fig. 5, it is common that DL occupies a main time resource, which causes a coverage imbalance between DL and UL. Compared with a frequency division duplex (frequency division duplexing, FDD) system, the uplink coverage of the TDD system is poorer, and the time delay is larger.

Aiming at the problems of uplink coverage and uplink delay in a TDD system, a SBFD scheme is proposed in the release (R) 18 standard. In SBFD scheme, one component carrier (component carrier, CC) may include multiple subbands, and transmission directions of different subbands may be different.

For example, fig. 6 is a schematic diagram of time-frequency resource allocation in a SBFD scheme. On the three time units located in the middle, one carrier may be divided into three subbands, the middle being the uplink subband available for uplink transmission, identified in the figure as UL. The upper and lower subbands are downlink subbands that can be used for downlink transmission, and are denoted by DL in the figure.

The upper subband refers to a subband having a higher frequency, the lower subband refers to a subband having a lower frequency, and the middle subband refers to a subband having a frequency between the frequency of the upper subband and the frequency of the lower subband. The first or last time unit may be referred to as a non-SBFD (non-SBFD) time unit and any time unit located in the middle may be referred to as a SBFD time unit. The time units may be, for example, time slots or symbols.

For another example, fig. 7 is a schematic diagram of time-frequency resource allocation in a SBFD scheme. On the three time units located in the middle, one carrier may be divided into two subbands, the upper subband being the downlink subband available for downlink transmission, identified in the figure as DL. The lower sub-band is the uplink sub-band available for uplink transmission, identified in the figure as UL.

It is believed that in the SBFD scheme, the network device may implement simultaneous transmission and reception of signals over different frequency domain resources or subbands over SBFD time units. Currently, in the R19 standard, a network device may use a sub-band full duplex scheme, and a terminal device may use a sub-band half duplex scheme. The terminal device adopts a sub-band half duplex scheme, which means that the terminal device can only receive or transmit signals in SBFD time units and can not receive and transmit signals at the same time.

For the time domain configuration of SBFD, there are two possible configurations depending on whether SBFD symbols and non-SBFD symbols are contained in one slot at the same time. In one possible configuration, the time domain configuration of SBFD is slot-level, i.e., the symbols contained in one slot are either all configured as SBFD symbols or all configured as non-SBFD symbols. In another possible configuration, the time domain configuration of SBFD is symbol level, i.e., one slot contains symbols, one part may be configured as SBFD symbols, and another part may be configured as non-SBFD symbols. The time domain configuration mode of SBFD is not limited in any way in the embodiment of the present application. Wherein SBFD symbols may be symbols configured with SBFD operations (operaton), and non-SBFD symbols may be symbols not configured with SBFD operations. For uplink transmission, the non-SBFD symbols may be uplink symbols or flexible symbols, and for downlink transmission, the non-SBFD symbols may be downlink symbols or flexible symbols.

In SBFD schemes, the available uplink transmission resources for the terminal device are increased compared to TDD systems. Therefore, the SBFD scheme can effectively promote uplink coverage and reduce uplink time delay.

In the SBFD scheme, since signal power in one sub-band leaks into other adjacent sub-bands, interference between UL and DL, i.e., cross-link interference (CLI) is caused. CLI can be classified into the following two types according to the source of interference generation:

1) Type 1, user Equipment (UE) and CLI between UEs (UE-to-UE CLI).

The UE-to-UE CLI refers to interference generated by an uplink signal sent by one UE in the cell to a downlink signal received by another UE in the cell or a neighboring cell. For example, in fig. 8, interference caused by an uplink signal transmitted from ue#1 or ue#2 to gnb#1 receiving a downlink signal from gnb#0 by ue#0 may be referred to as UE-to-UE CLI. The embodiment of the application mainly measures and reports the UE-to-UE CLI.

2) Type 2, CLI (gNB-to-gNB CLI) between next generation base stations (next generat ion nodeB, gNB) and gNB.

GNB-to-gNB CLI refers to interference generated by a downlink signal sent by one base station on an uplink signal received by another base station. For example, in fig. 8, interference caused by the downlink signal from gnb#0 to ue#0 to the uplink signal from ue#1 or ue#2 received by gnb#1 may be referred to as gNB-to-gNB CLI.

In the UE-to-UE CLI measurement and reporting mechanism, one UE sends a sounding REFERENCE S IGNAL (SRS) to the gcb where it resides, and another UE residing in the own cell or neighboring cell measures the SRS and reports the measurement result to the serving cell of another UE. As shown in fig. 8, ue#1 may transmit SRS to gnb#1. Ue#0 may measure the SRS transmitted by ue#1 and transmit the measurement result to gnb#0, or ue#2 may measure the SRS transmitted by ue#1 and transmit the measurement result to gnb#1. The measurement indicators may include SRS-reference signal received power (REFERENCE S IGNAL RECEIVING power, RSRP) and/or CLI-received signal strength indication (RECEIVED S IGNAL STRENGTH INDICAT ion, RSSI), among others.

For a dynamic TDD system, a layer (L) 3 level UE-to-UE CLI (hereinafter referred to as "L3UE-to-UE CLI") measurement and reporting mechanism is defined in the R16 standard. The L3UE-to-UE CLI measurement and reporting mechanism refers to UE-to-UE CLI measurement and reporting performed at the radio resource control (radio resource control, RRC) protocol layer level. For example, RRC signaling may trigger UE-to-UE CLI measurements, and RRC signaling may be used for measurement result reporting.

For SBFD schemes, an L1 or L2 level UE-to-UE CLI (hereinafter referred to as "L1/L2 UE-to-UE CLI") measurement and reporting mechanism is introduced in the R19 standard. The measurement and reporting mechanism refers to UE-to-UE CLI measurement and reporting at the physical layer or data link layer level. For example, downlink control information (downl ink control informat ion, DCI) or MAC Control Element (CE) may trigger UE-to-UE CLI measurement and report the measurement result through an uplink physical shared channel (phys ical upl INK SHARE CHANNEL, PUSCH) and/or an uplink physical control channel (phys ical upl ink control channel, PUCCH). Compared with an L3 UE-to-UE CLI measurement and reporting mechanism, the L1/L2 UE-to-UE CLI measurement and reporting mechanism is more flexible, and the time delay of measurement and reporting is shorter, so that the change of the UE-to-UE CLI can be tracked better, the measurement result is more accurate, and further, the UE-to-UE CLI can be eliminated better.

Further, the R19 standard also refers to multiplexing of the L1/L2 UE-to-UE CLI measurement and reporting mechanism with the existing CSI measurement and reporting mechanism. The CSI measurement is mainly used for channel measurement and interference measurement between the UE and the gNB.

Fig. 9 is a schematic diagram of time-frequency resource allocation in SBFD GB schemes, and fig. 10 is a schematic diagram of time-frequency resource allocation in another SBFD GB scheme.

In order to reduce cross-link interference, a guard band may be introduced between adjacent downlink and uplink sub-bands, as shown in fig. 9 and 10, in which no data transmission is performed, and the base station device and the terminal device perform downlink and uplink transmission only on the downlink and uplink sub-bands, respectively. In addition, the base station device and the terminal device may set the filter operating bandwidths according to the downlink sub-band and the uplink sub-band, for example, the terminal device sets the reception filter bandwidth according to the downlink sub-band and sets the transmission filter bandwidth according to the uplink sub-band, so that the guard band may reduce the effect of cross-link interference between transmission in the downlink sub-band and transmission in the uplink sub-band.

As the capabilities of different terminal devices may be different, the transition band size may also be different when implementing the filter. The transition zone of the filter is generally arranged in the protection zone, terminal equipment with different capabilities has different requirements on the size of the protection zone, terminal equipment with stronger capabilities can be provided with smaller protection zones, and terminal equipment with weaker capabilities needs to be provided with larger protection zones.

If the sizes of the guard bands between the SBFD downlink sub-bands and the uplink and downlink sub-bands configured by the network device for all the terminal devices are the same, for the UE with weaker capability, the resource transmission is affected due to too large CLI, and for the terminal device with stronger capability, the resource waste exists due to the fact that the guard bands cannot be used for data transmission, and the system efficiency is affected.

The terminal device supporting SBFD functions may also be referred to simply as SBFD terminal device.

The frequency domain resource allocation method of SBFD uplink and downlink subbands and GB provided by the embodiment of the present application will be specifically described below with reference to fig. 1 to 10.

Fig. 11 shows a flowchart of a method for configuring uplink and downlink subbands and GB frequency domain resources of SBFD according to an embodiment of the present application, including the following steps:

Step S1101, the terminal device sends a first signaling to the network device. Accordingly, the network device receives the first signaling from the terminal device.

The first signaling includes first indication information and/or second indication information.

Optionally, the first signaling may carry first indication information. The first indication information may be whether the terminal device supports SBFD GB capabilities. The capability of supporting SBFD GB is indicated when the first indication information assumes the first status value, and the capability of not supporting SBFD GB is indicated when the first indication information assumes the second status value. For example, the first state value may be true, or the first state value may be 1. The first state value may be false, or the first state value may be 0. Or the first indication indicates the ability to support SBFD GB when present and indicates the ability to not support SBFD GB when not present.

Alternatively, the first signaling may carry the first indication information and the second indication information. The first indication information may be whether the terminal device supports SBFD GB capabilities. The capability of supporting SBFD GB is indicated when the first indication information assumes the first status value, and the capability of not supporting SBFD GB is indicated when the first indication information assumes the second status value. For example, the first state value may be true, or the first state value may be 1. The first state value may be false, or the first state value may be 0. Or the first indication information indicates the capability of support SBFD GB when present. The second indication information indicates a bandwidth SBFD GB supported by the terminal device, for example, indicates a bandwidth of a minimum SBFD GB supported by the terminal device. The bandwidth SBFD GB may be absolute, for example X RB, X MHz or X kHz, X being greater than 0.

Optionally, the second indication information may be carried in the first signaling. The second indication information indicates a bandwidth SBFD GB supported by the terminal device, for example, indicates a bandwidth of a minimum SBFD GB supported by the terminal device. The bandwidth SBFD GB may be absolute, for example X RB, X MHz, or X kHz, X being equal to or greater than 0. X=0 indicates that SBFD GB is not supported, X is not equal to 0 indicates that SBFD GB is supported, and the bandwidth of SBFD GB is supported.

Optionally, the bandwidth SBFD GB may also be a relative value, e.g., the bandwidth of SBFD GB is related to the downlink subband bandwidth and/or the uplink subband bandwidth. Alternatively, the bandwidth SBFD GB, hereinafter denoted by GB Size, may be determined in particular by:

GB size=z×bbbf1, or GB size=z×bbf2, or GB size=z×max (BW 1, BW 2), or GB size=z×min (bbf1+bf2), where BW1 is the bandwidth of the downlink subband, BW2 is the bandwidth of the uplink subband, further BW1 may be the bandwidth of the downlink subband adjacent to GB, and BW2 may be the bandwidth of the uplink subband adjacent to GB. Z is a coefficient, and Z >0, for example, Z may take the values of 0.8, 0.9, 0.1, 0.12, 0.13, etc.

Optionally, the second indication information may also be a value of Z, or a bit indication corresponding to the value of Z. Taking a 2-bit indication as an example, 00,11,10,11 respectively correspond to different values of Z.

Optionally, the bandwidths of SBFD GB are related to subcarrier spacing (subcarrier spacing, SCS) supported by the terminal device, different SCS corresponding to different SBFD GB bandwidths.

Alternatively, the first signaling may be newly introduced signaling. Or the existing signaling can be multiplexed, which is the signaling carrying the first indication information and/or the second indication information based on the existing signaling. The first signaling may be higher layer signaling, such as radio resource control (radio resource control, RRC) signaling.

Step S1101 is an optional step, and the terminal device may or may not send the first signaling to the network device.

Step S1102, the network device sends a second signaling to the terminal device. Accordingly, the terminal device receives the second signaling from the network device.

The second signaling is used to indicate the uplink and downlink subbands of SBFD and the frequency domain resource allocation of GB. The frequency domain resource allocation of the up and down subbands and GB of SBFD may be at least one of the frequency domain resource allocation of the SBFD up subband, the frequency domain resource allocation of the SBFD down subband, or the frequency domain resource allocation of SBFD GB.

The frequency domain resources may be further extended to frequency domain locations and/or bandwidths.

Alternatively, the frequency domain resource configuration of the uplink and downlink subbands and GB of SBFD may be carried by an explicit manner, or the frequency domain resource configuration of the uplink and downlink subbands and GB of SBFD may be carried by an implicit manner.

The second signaling may include the first parameter and/or the second parameter. For example, the first parameter is used to indicate at least one of SBFD GB frequency domain resources, or SBFD frequency domain resources of the uplink sub-band. The second parameter is used to indicate at least one of SBFD frequency domain resources of an uplink subband or SBFD frequency domain resources of a downlink subband.

Optionally, in the explicit indication manner, the second signaling includes at least a first parameter, where the first parameter is used to indicate at least one of a frequency domain position of SBFD GB and/or a bandwidth of SBFD GB, a frequency domain position of SBFD uplink subband and/or a bandwidth of SBFD uplink, or a frequency domain position of SBFD downlink subband and/or a bandwidth of SBFD downlink subband. For example, the first parameter is used to indicate at least one of a frequency domain location of SBFD GB and/or a bandwidth of SBFD GB, or a frequency domain location of SBFD uplink sub-bands and/or a bandwidth of SBFD GB.

The SBFD GB bandwidth configured by the network device to the terminal device is not less than the SBFD GB bandwidth supported by the terminal device.

Optionally, in the implicit indication manner, the second signaling includes at least a second parameter, where the second parameter is used to indicate at least one of SBFD uplink subband frequency domain position and/or SBFD uplink subband bandwidth, or SBFD downlink subband frequency domain position and/or SBFD downlink subband bandwidth. The bandwidth SBFD GB may be the frequency separation between adjacent SBFD downstream subbands and SBFD upstream subbands. The frequency interval between adjacent SBFD downstream subbands and SBFD upstream subbands is defined as the frequency interval between the frequency end position of the lower-frequency subband and the frequency start position of the higher-frequency subband.

The frequency interval between adjacent SBFD uplink sub-bands and SBFD downlink sub-bands is not less than the bandwidth of SBFD GB supported by the terminal device.

The second signaling configuration may be a frequency domain resource configuration of uplink and downlink subbands and GB of SBFD dedicated to the UE (UE-Specific), or may be a frequency domain resource configuration of uplink and downlink subbands and GB of SBFD common to cells (cell-common).

The network device may configure a set of UE-specific SBFD uplink and downlink subbands and GB frequency domain resources, and may also configure a set of cell-common SBFD uplink and downlink subbands and GB frequency domain resources.

The frequency domain resources of the uplink and downlink sub-bands and GB common to the cell and the frequency domain resources of the uplink and downlink sub-bands and GB dedicated to the UE satisfy one or more of the following 3 relations:

1. the frequency domain resource of the SBFD uplink sub-band common to the cells is the same as the frequency domain resource of the SBFD uplink sub-band exclusive to the UE;

2. The frequency domain resource of the GB of SBFD which is common to the cell is the same as the frequency domain resource of the GB of SBFD which is exclusive to the UE, or the frequency domain resource of SBFD GB which is common to the cell is a subset of the frequency domain resource of SBFD GB which is exclusive to the UE;

3. The frequency domain resources of the SBFD downlink sub-band common to the cell are the same as those of the SBFD downlink sub-band dedicated to the UE, or the frequency domain resources of the SBFD downlink sub-band dedicated to the UE are a subset of those of the SBFD downlink sub-band common to the cell.

Accordingly, the network device and/or the terminal device respectively need to perform filter setting.

The network device configures the filter working bandwidth according to the bandwidth of the uplink sub-band, the bandwidth of the downlink sub-band and the bandwidth of the GB of the common SBFD of the cells. For example, the operating bandwidth of the transmit filter is configured according to the bandwidth of the downlink sub-band of SBFD, which is common to the cells, and the operating bandwidth of the receive filter is configured according to the bandwidth of the uplink sub-band of SBFD, which is common to the cells.

The terminal equipment configures the working bandwidth of the filter according to the bandwidth of the uplink sub-band, the bandwidth of the downlink sub-band and the GB bandwidth of the dedicated SBFD of the UE. For example, the working bandwidth of the transmitting filter is configured according to the bandwidth of the SBFD uplink sub-band dedicated to the UE, and the working bandwidth of the receiving filter is configured according to the bandwidth of the SBFD downlink sub-band dedicated to the UE.

At least one of the frequency domain resources SBFD GB, the frequency domain resources of the SBFD uplink subband, or the frequency domain resources of the SBFD uplink subband configured in step S1102 are all for the same SCS.

Fig. 12 shows a flowchart of another method for configuring uplink and downlink subbands and GB frequency domain resources of SBFD according to an embodiment of the present application, including the following steps:

Step S1201, the network device sends a third signaling to the terminal device. Accordingly, the terminal device receives the third signaling from the network device.

The third signaling is used to indicate the frequency domain resource configuration of the uplink and downlink subbands and GB of the N sets SBFD, where N is an integer greater than or equal to 1. The frequency domain resource allocation of the up and down subbands and GB of SBFD may be at least one of the frequency domain resource allocation of the SBFD up subband, the frequency domain resource allocation of the SBFD down subband, or the frequency domain resource allocation of SBFD GB.

Alternatively, the frequency domain resource configuration of the uplink and downlink subbands and GB of the N sets SBFD may be carried by an explicit manner, or the frequency domain resource configuration of the uplink and downlink subbands and GB of the N sets SBFD may be carried by an implicit manner.

The third signaling may include a third parameter and/or a fourth parameter. For example, the third parameter is used to indicate at least one of N sets SBFD GB of frequency domain resources, or N sets SBFD of frequency domain resources of the uplink sub-band. The fourth parameter is used to indicate at least one of frequency domain resources for N sets SBFD of uplink subbands or frequency domain resources for N sets SBFD of downlink subbands.

Optionally, in the explicit indication manner, the third signaling includes at least a third parameter, where the third parameter is used to indicate at least one of a frequency domain position of N sets SBFD GB and/or a bandwidth of SBFD GB, a frequency domain position of N sets SBFD uplink sub-bands and/or a bandwidth of SBFD uplink, or a frequency domain position of N sets SBFD downlink sub-bands and/or a bandwidth of SBFD downlink sub-bands. For example, the third parameter is used to indicate at least one of a frequency domain position of the N sets SBFD GB and/or a bandwidth of the SBFD GB and/or a frequency domain position of the N sets SBFD uplink sub-bands and/or a bandwidth of the uplink sub-bands.

Optionally, in the implicit indication manner, the third signaling includes at least a fourth parameter, where the fourth parameter is used to indicate at least one of a frequency domain position of the N sets SBFD of uplink subbands and/or a bandwidth of the SBFD uplink subbands, or a frequency domain position of the N sets SBFD of downlink subbands and/or a bandwidth of the SBFD downlink subbands. The bandwidth SBFD GB may be the frequency separation between adjacent SBFD downstream subbands and SBFD upstream subbands. The frequency interval between adjacent SBFD downstream subbands and SBFD upstream subbands is defined as the frequency interval between the frequency end position of the lower-frequency subband and the frequency start position of the higher-frequency subband.

When n=1, the SBFD GB bandwidth configured by the network device to the terminal device is not less than the maximum value in the SBFD terminal device first capability set. Wherein SBFD the first set of capabilities of the terminal device is predefined or determined according to predefined rules.

The first capability set of SBFD terminal device includes one or more bandwidths predefined SBFD GB, and each bandwidth SBFD GB may have a value of X RB, X MHz, or X kHz, where X is greater than or equal to 0.

The SBFD terminal device first capability set contains one or more bandwidths of SBFD GB determined according to predefined rules. The predefined rule may be that the bandwidth SBFD GB is related to the downlink subband bandwidth and/or the uplink subband bandwidth. Specifically, GB size=z×bbbf1, or GB size=z×bbf2, or GB size=z×max (BW 1, BW 2), or GB size=z×min (bbf1+bf2), where GB Size is SBFD GB bandwidth, BW1 is bandwidth of downlink subband, BW2 is bandwidth of uplink subband, further BW1 may be bandwidth of downlink subband adjacent to GB, and BW2 may be bandwidth of uplink subband adjacent to GB. Z is a coefficient, and Z >0, for example, Z may take the values of 0.8, 0.9, 0.1, 0.12, 0.13, etc.

Optionally, when n=1, if the bandwidth of SBFD GB indicated by the third parameter is smaller than the SBFD GB bandwidth supported by the terminal device or the frequency interval between the adjacent SBFD downlink sub-band and SBFD uplink sub-band indicated by the fourth parameter is smaller than the GB bandwidth supported by the terminal device, the terminal device keeps the frequency domain resource of SBFD uplink sub-band unchanged, and at least one of the frequency domain resource of the third SBFD GB or the frequency domain resource of the third SBFD downlink sub-band is redetermined. The bandwidth of the third SBFD GB is not less than the bandwidth of SBFD GB supported by the terminal device, and the frequency separation of the third downlink sub-band and the adjacent SBFD uplink sub-band is not less than the bandwidth of SBFD GB supported by the terminal device.

Optionally, when n=1, if the bandwidth of SBFD GB indicated by the third parameter is smaller than the SBFD GB bandwidth supported by the terminal device, or the frequency interval between the adjacent SBFD downlink sub-band and SBFD uplink sub-band indicated by the fourth parameter is smaller than the SBFD GB bandwidth supported by the terminal device, the network device keeps the bandwidth of SBFD downlink sub-band unchanged. If the downlink transmission of the resource scheduling falls outside the bandwidth range of the SBFD downlink sub-band supported by the terminal equipment, the terminal equipment only receives the transmission data in the supported SBFD downlink sub-band bandwidth, and considers the transmission data falling outside the supported SBFD downlink sub-band bandwidth as punching processing.

Alternatively, the third signaling may be newly introduced signaling. Or the existing signaling can be multiplexed, which is the signaling carrying the third parameter or the fourth parameter based on the existing signaling. The third signaling may be a system message, e.g., a system information block (systeminformat ion block, SIB).

At least one of the frequency domain resources of the N sets SBFD GB, the frequency domain resources of the N sets SBFD uplink sub-bands, or the frequency domain resources of the N sets SBFD uplink sub-bands configured in step S1201 is for the same SCS, where N is an integer greater than or equal to 1.

Step S1202, the terminal device sends a fourth signaling to the network device. Accordingly, the network device receives fourth signaling from the terminal device.

The fourth signaling may be carried in a Physical Random Access Channel (PRACH), a message a (messageA, msgA) physical uplink shared channel (Phys ical upl INK SHARED CHANNEL, PUSCH), or a message3 (Msg 3) PUSCH.

The fourth signaling includes the third indication information and/or the fourth indication information.

Optionally, the third indication information may be carried in the fourth signaling. The third indication information may be whether the terminal device supports SBFD GB capabilities. The third indication information indicates the capability of supporting SBFD GB when the third indication information is the first state value, and indicates the capability of not supporting SBFD GB when the third indication information is the second state value. For example, the first state value may be true, or the first state value may be 1. The first state value may be false, or the first state value may be 0. Or the third indication indicates the capability of supporting SBFD GB when it appears, and indicates the capability of not supporting SBFD GB when it does not appear.

Optionally, the third indication information and the fourth indication information may be carried in the fourth signaling. The third indication information may be whether the terminal device supports SBFD GB capabilities. The third indication information indicates the capability of supporting SBFD GB when the third indication information is the first state value, and indicates the capability of not supporting SBFD GB when the third indication information is the second state value. For example, the first state value may be true, or the first state value may be 1. The first state value may be false, or the first state value may be 0. Or when a third indication appears, indicating the capability of support SBFD GB. The fourth indication information indicates a bandwidth SBFD GB supported by the terminal device, for example, indicates a bandwidth of a minimum SBFD GB supported by the terminal device. The bandwidth SBFD GB may be absolute, for example X RB, X MHz or X kHz, X being greater than 0.

Optionally, fourth indication information may be carried in the fourth signaling. The fourth indication information indicates a bandwidth SBFD GB supported by the terminal device, for example, indicates a bandwidth of a minimum SBFD GB supported by the terminal device. The bandwidth SBFD GB may be absolute, for example X RB, X MHz, or X kHz, X being equal to or greater than 0. X=0 indicates that SBFD GB is not supported, X is not equal to 0 indicates that SBFD GB is supported, and the bandwidth of SBFD GB is supported.

Optionally, the fourth indication information may also be a value of Z, or a bit indication corresponding to the value of Z. Taking a 2-bit indication as an example, 00,11,10,11 respectively correspond to different values of Z.

Step S1202 is an optional step, and the terminal device may or may not send the fourth signaling to the network device.

Optionally, after the network device receives the fourth signaling of the terminal device and obtains the bandwidth SBFD GB supported by the terminal device indicated by the fourth indication information, at least one of a set of frequency domain resources of N sets SBFD GB, a set of frequency domain resources of N sets SBFD uplink sub-bands, or a set of frequency domain resources of N sets SBFD downlink sub-bands is determined according to the bandwidth SBFD GB supported by the terminal device, and data transmission is performed with the terminal device by using at least one of the determined frequency domain resources of SBFD GB, the determined frequency domain resources of SBFD uplink sub-bands, or the determined frequency domain resources of SBFD downlink sub-bands.

Step S1203, the network device sends a fifth signaling to the terminal device. Accordingly, the terminal device receives the fifth signaling from the network device.

Optionally, in step S1202, after receiving the bandwidth SBFD GB supported by the terminal device indicated by the fourth indication information, the network device reconfigures at least one of the frequency domain resource of the second SBFD GB, the frequency domain resource of the second SBFD uplink subband, or the frequency domain resource of the second SBFD downlink subband according to the bandwidth SBFD GB supported by the terminal device.

The bandwidth of the second SBFD GB reconfigured by the network device is not less than the bandwidth of SBFD GB supported by the terminal device, or the frequency separation of the adjacent second SBFD uplink sub-band and second SBFD downlink sub-band is not less than the bandwidth of SBFD GB supported by the terminal device.

The fifth signaling is for carrying at least one of the frequency domain resources of the second SBFD GB, the frequency domain resources of the second SBFD uplink sub-band, or the frequency domain resources of the second SBFD downlink sub-band. .

The flow of reconfiguration may refer to the step when n=1 in S1201.

Fig. 13 shows a flowchart of another method for configuring uplink and downlink subbands and GB frequency domain resources of SBFD according to an embodiment of the present application, including the following steps:

step S1301, the network device sends a sixth signaling to the terminal device. Accordingly, the terminal device receives the sixth signaling from the network device.

The sixth signaling may include a sixth parameter, where the sixth parameter is configured to indicate a frequency domain resource of a SBFD uplink subband and a frequency domain resource of a SBFD downlink subband of the cell common (CEL L SPECIFIC). Optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of SBFD uplink and downlink subbands.

Optionally, the sixth signaling may be carried in a system message block (System Informat ion Block, SIB), such as system message block 1.

Step S1302, the network device sends a seventh signaling to the terminal device. Accordingly, the terminal device receives seventh signaling from the network device.

The seventh signaling may include a seventh parameter included therein. Optionally, the seventh parameter is used to indicate a configuration of frequency domain resources of a SBFD uplink subband and frequency domain resources of a SBFD downlink subband that are UE specific. Optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of SBFD uplink and downlink subbands.

At this time, the network device configures the terminal device with two sets of frequency domain resources of SBFD uplink sub-bands, namely, the frequency domain resources of SBFD uplink sub-band common to the cells and the frequency domain resources of SBFD uplink sub-band dedicated to the UE. The frequency domain resources of the common SBFD uplink sub-band of the cell indicated by the sixth parameter and the frequency domain resources of the dedicated SBFD uplink sub-band of the UE indicated by the seventh parameter are identical, which has the advantage that the overlapping of the frequency domain resources of the uplink sub-band of one UE and the downlink sub-band of another UE can be avoided, so that the uplink and downlink co-channel interference can be avoided. In the case of keeping the frequency domain resource configuration of the SBFD uplink sub-band unchanged, the frequency domain resource of the SBFD downlink sub-band may be reconfigured by the seventh signaling, and optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of the SBFD uplink and downlink sub-bands.

Optionally, the seventh parameter only indicates the frequency domain resource of the downlink sub-band SBFD dedicated to the UE, and does not indicate the frequency domain resource of the uplink sub-band SBFD, at this time, there are no frequency domain resources of the uplink sub-bands SBFD, the frequency domain resource of the downlink sub-band SBFD may be reconfigured by the seventh signaling, and optionally, the frequency domain resource of SBFD GD may be implicitly confirmed by the frequency domain resource of the uplink sub-band SBFD. The terminal equipment determines SBFD resources according to the frequency domain resources of the SBFD uplink band common to the cells and the frequency domain resources of the SBFD downlink sub-band exclusive to the UE.

Optionally, the seventh signaling may be carried in RRC.

Fig. 14 is a flowchart illustrating another method for configuring uplink and downlink subbands and GB frequency domain resources of SBFD according to an embodiment of the present application, including the following steps:

Step S1401, the network device sends an eighth signaling to the terminal device. Accordingly, the terminal device receives the eighth signaling from the network device.

The eighth signaling may include an eighth parameter indicating a frequency domain resource of a SBFD uplink subband common to the cells (CEL L SPECIFIC).

Optionally, the eighth signaling may be carried in a system message block (System Informat ion Block, SIB), such as system message block 1.

Step S1402, the network device sends a ninth signaling to the terminal device. Accordingly, the terminal device receives the ninth signaling from the network device.

The ninth signaling may include a ninth parameter included therein. Optionally, the ninth parameter is used to indicate a configuration of frequency domain resources of a SBFD downlink subband dedicated to the UE (UE specific).

At this time, the network device configures the frequency domain resource of the SBFD uplink sub-band common to the cell and the frequency domain resource of the SBFD downlink sub-band dedicated to the UE to the terminal device. Optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of SBFD uplink and downlink subbands. The terminal equipment determines SBFD resources according to the frequency domain resources of the SBFD uplink band common to the cells and the frequency domain resources of the SBFD downlink sub-band exclusive to the UE.

Optionally, the ninth signaling may be carried in RRC.

Fig. 15 shows a flowchart of another method for configuring uplink and downlink subbands and GB frequency domain resources of SBFD according to an embodiment of the present application, including the following steps:

Step S1501, the network device sends tenth signaling to the terminal device. Accordingly, the terminal device receives tenth signaling from the network device.

Tenth signaling may include a tenth parameter indicating a configuration of frequency domain resources of SBFD uplink subbands and SBFD downlink subbands of cell common (CEL L SPECIFIC). Optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of SBFD uplink and downlink subbands.

Optionally, tenth signaling may be carried in a system message block (System Informat ion Block, SIB), such as system message block 1.

Step S1502, the network device sends an eleventh signaling to the terminal device. Accordingly, the terminal device receives eleventh signaling from the network device.

The eleventh signaling may include an eleventh parameter included therein. Optionally, the eleventh parameter is used to indicate a configuration of frequency domain resources of SBFD uplink subbands and SBFD downlink subbands that are UE specific. Optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by the frequency domain resource of SBFD uplink and downlink subbands.

At this time, the network device configures the terminal device with two sets of frequency domain resources of SBFD uplink sub-bands, namely, the frequency domain resources of SBFD uplink sub-band common to the cells and the frequency domain resources of SBFD uplink sub-band dedicated to the UE. The frequency domain resources of the common SBFD downlink sub-band of the cell indicated by the tenth parameter and the frequency domain resources of the dedicated SBFD downlink sub-band of the UE indicated by the eleventh parameter are identical, which has the advantage that the overlapping of the frequency domain resources of the uplink sub-band of one UE and the downlink sub-band of another UE can be avoided, so that the uplink and downlink co-channel interference can be avoided. In the case of keeping the frequency domain resource configuration of the SBFD downlink sub-band unchanged, the frequency domain resource of the SBFD uplink sub-band may be reconfigured by eleventh signaling, and optionally, the frequency domain resource of SBFD GD may be implicitly acknowledged by SBFD uplink and downlink sub-band.

Optionally, the eleventh parameter only indicates the frequency domain resource of the dedicated SBFD uplink subband of the UE, and does not indicate the frequency domain resource of the SBFD downlink subband, at this time, there are no frequency domain resources of the two SBFD downlink subbands, the frequency domain resource of the SBFD uplink subband may be reconfigured by the eleventh signaling, and optionally, the frequency domain resource of SBFD GD may be implicitly confirmed by the frequency domain resource of the SBFD uplink and downlink subbands. The terminal equipment determines SBFD resources according to the frequency domain resources of the SBFD downlink band common to the cells and the frequency domain resources of the SBFD uplink sub-band exclusive to the UE.

Optionally, the eleventh signaling may be carried in RRC.
