Description

Technical Field

Background

In a New Radio, NR RedCap (Reduced Capability) scenario, the terminal supports a frequency division (Frequency Division Duplex, FDD) duplex mode, a time division duplex (Time Division Duplex, TDD) mode, and a half duplex FDD mode.

In the half duplex FDD mode, the terminal cannot transmit and receive simultaneously. Currently, in a ground system, because the distance between the base station and the terminal is relatively short, and the base station can know the timing advance of the actual use of the terminal, whether the base station collides with the terminal side in the uplink and downlink is expected.

However, in the Non-terrestrial network (Non-TERRESTRIAL NETWORK, NTN), since the transmission delay between the satellite and the terminal is estimated by the terminal and precompensated in advance, the base station cannot know the timing advance actually used by the terminal, so that uplink and downlink collision occurs at the terminal side due to unreasonable transmission configuration of the base station.

The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The technical scheme provided by the embodiment of the application can be suitable for various systems, such as a 5G system.

The terminal according to the embodiment of the application can be a device for providing voice and/or data connectivity for a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, etc. The names of terminals may also be different in different systems, for example in a 5G system, a terminal may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as Personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal DIGITAL ASSISTANT, PDA) and the like. The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile station), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (ACCESS TERMINAL), user terminal device (user terminal), user agent (user agent), user equipment (user device), and embodiments of the present application are not limited.

The network device according to the embodiment of the present application may be a base station, where the base station may include a plurality of cells for providing services for the terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be configured to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), etc., which are not limited in the embodiment of the present application. In some network structures, the network devices may include centralized unit (centralized unit, CU) nodes and Distributed Unit (DU) nodes, which may also be geographically separated.

For example, in an embodiment of the present application, multiple input Multiple output (Multi Input Multi Output, MIMO) transmission may be performed between the network device and the terminal device by using one or more antennas, and the MIMO transmission may be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

In the half duplex FDD mode, the terminal cannot transmit and receive simultaneously. Currently, in a ground system, since the distance between the base station and the terminal is relatively short, and the base station can know the timing advance (TIMING ADVANCE, TA) actually used by the terminal, whether the base station collides with the terminal side in the uplink and downlink is expected.

However, in NTN, since the transmission delay between the satellite and the terminal is estimated by the terminal and precompensated in advance, the base station cannot know the timing advance actually used by the terminal, which may cause uplink and downlink collision at the terminal side due to unreasonable transmission configuration of the base station.

In order to effectively solve the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station, the embodiment of the present application provides a transmission configuration method, and hereinafter, with reference to the embodiment of the present application and related drawings, a technical solution in the embodiment of the present application will be clearly and completely described, and obviously, the described embodiment is only a part of embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Fig. 1 is a flowchart of a method for determining a transmission configuration method according to an embodiment of the present application, which is applied to a network device, such as a base station, for example, referring to fig. 1, the method may include:

s101, timing advance reported by a receiving terminal.

In the embodiment of the present application, the timing advance may be the timing advance of the last report of the terminal, or may be the timing advance of the last report of the terminal, or may be specifically set according to actual needs.

S102, determining a target period based on the timing advance, and configuring the terminal to execute transmission operation outside the target period.

The target period may be understood as a ambiguity period, i.e. a period in which the network device cannot know whether the terminal is in Uplink (UL) transmission or Downlink (DL) reception.

After determining the target period, in view of the fact that the network device cannot know whether the terminal is in uplink transmission or downlink reception in the target period, the network device configures the terminal to not perform other transmission operations in the target period, in other words, configures the terminal to perform other transmission operations outside the target period.

It can be seen that in the embodiment of the present application, the network device determines the target period by receiving the timing advance reported by the terminal and based on the timing advance, and configures the terminal to perform the transmission operation outside the target period, so that the transmission configuration can be performed in a targeted manner, and the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station can be effectively solved.

Based on the embodiment shown in fig. 1, for example, when determining the target period based on the timing advance in S102, at least three possible scenarios may be included:

in one possible scenario, one of the uplink and downlink reception is semi-statically configured, and the other is dynamically scheduled.

Illustratively, in this possible scenario, there are two cases, one is that the uplink is Semi-static, i.e., semi-static UL, and the downlink is received as Dynamic, i.e., DYNAMIC DL, and the other is that the uplink is Dynamic, i.e., dynamic UL, and the downlink is Semi-static, i.e., semi-static DL.

In one case, the uplink transmission is semi-static configured and the downlink reception is dynamic scheduling. When determining the target period based on the timing advance, the method can determine a first period before transmitting the initial symbol based on the timing advance of the uplink transmission, a preset timing threshold offset value and the conversion time of the terminal from downlink reception to uplink transmission, and determine a second period after the end of transmitting the symbol based on the timing advance of the uplink transmission, the timing threshold offset value and the conversion time of the terminal from uplink transmission to downlink reception, wherein the target period comprises the first period and the second period, and the transmission operation is downlink reception.

The first period may be understood as a ambiguity period before the terminal transmits the start symbol, and the second period may be understood as a ambiguity period after the terminal transmits the end symbol, during which the network device configures the terminal not to perform downlink reception, in other words, the network device reconfigures the terminal to perform downlink reception outside of the two ambiguity periods.

For example, the first period may be denoted as N1, the second period may be denoted as N2, and fig. 2 is a schematic diagram of the first period and the second period according to the embodiment of the present application, where the first period before the start symbol is sent may be determined based on n1= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the second period after the end of the symbol is sent may be determined based on n2= reported TA-offsetThresholdTAr17+n _TX-RX*T_C.

Wherein reported TA denotes a timing advance, offsetThresholdTAr17 denotes a preset timing threshold offset value, N _RX-TX denotes a switching time of a terminal from downlink reception to uplink transmission, T _C denotes a time unit, and N _TX-RX denotes a switching time of a terminal from uplink transmission to downlink reception.

For example, offsetThresholdTAr ms to 16ms may be a value in the range of 0.5ms, and may be specifically set according to actual needs.

It can be seen that, when the uplink transmission is semi-static configuration and the downlink reception is dynamic scheduling, the network device can determine a first period before the terminal transmits the start symbol based on the timing advance of the uplink transmission, the preset timing threshold offset value and the conversion time of the terminal from the downlink reception to the uplink transmission, and determine a second period after the terminal transmits the symbol to end based on the timing advance of the uplink transmission, the timing threshold offset value and the conversion time of the terminal from the uplink transmission to the downlink reception, and in the first period and the second period, the terminal is configured not to perform the downlink reception so as to restrict the downlink reception of the dynamic scheduling, thereby effectively solving the problem that the terminal side generates uplink and downlink collision due to unreasonable transmission configuration of the base station.

Example 1

In the case that the uplink transmission is Semi-static, i.e. Semi-static UL, and the downlink reception is dynamic scheduling, i.e. DYNAMIC DL, in order to avoid uplink and downlink collision at the terminal side, the method specifically includes:

If the higher layer configures the terminal to transmit the channel Sounding reference signal (Sounding REFERENCE SIGNAL, SRS), PUCCH or PUSCH on a group of symbols, a first period before the start symbol is transmitted may be determined based on n1= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, a second period after the end of the symbol is determined based on n2= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and in the first period and the second period, the terminal is configured to not receive the channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS) or the downlink control Information (Downlink Control Information, DCI) format of the PDSCH, so as to constrain the downlink reception of the dynamic scheduling, which may effectively solve the problem that uplink and downlink collision occurs on the terminal side due to unreasonable transmission configuration of the base station.

In one case, the uplink transmission is dynamic scheduling and the downlink reception is semi-static configuration. When determining the target period based on the timing advance, the method can determine a third period before receiving the initial symbol based on the timing advance of downlink reception, a preset timing threshold offset value and a transition time of the terminal from uplink transmission to downlink reception, and determine a fourth period after receiving the symbol end based on the timing advance of downlink reception, the timing threshold offset value and the transition time of the terminal from downlink reception to uplink transmission, wherein the target period comprises the third period and the fourth period, and the transmission operation is uplink transmission.

The third period may be understood as a ambiguity period before the terminal receives the start symbol, and the fourth period may be understood as a ambiguity period after the terminal receives the end symbol, where the network device configures the terminal not to perform uplink transmission during the two ambiguity periods, in other words, reconfigures the terminal to perform uplink transmission outside the two ambiguity periods.

For example, the third period may be denoted as N3, the fourth period may be denoted as N4, the third period before the terminal receives the start symbol may be determined based on n3= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and the fourth period after the terminal receives the symbol is determined based on n4= reported TA-offsetThresholdTAr17+n _RX-TX*T_C.

Wherein N _TX-RX represents a conversion time of the terminal from uplink to downlink, and N _RX-TX represents a conversion time of the terminal from downlink to uplink.

It can be seen that, when the uplink transmission is dynamically scheduled and the downlink reception is semi-statically configured, the target period is determined based on the timing advance, the preset timing threshold offset value and the transition time of the terminal from uplink to downlink, the third period before the terminal receives the start symbol is determined, the fourth period after the terminal receives the symbol is determined based on the timing advance and the timing threshold offset value of the downlink reception and the transition time of the terminal from downlink to uplink, and the terminal is configured not to perform uplink transmission in the third period and the fourth period, so as to restrict the dynamically scheduled uplink transmission, thereby effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Example 2

In the case that the uplink transmission is dynamically scheduled, i.e. Dynamic UL scheduling, and the downlink reception is Semi-static, i.e. Semi-static DL configuration, in order to avoid uplink and downlink collision at the terminal side, the uplink transmission of the Dynamic scheduling needs to be constrained, which specifically includes:

If the higher-layer configuration terminal receives PDCCH, PDSCH or CSI-RS or downlink Positioning reference signal (Positioning REFERENCE SIGNAL, PRS) on a group of symbols, a third period before receiving the starting symbol can be determined based on n3= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, a fourth period after receiving the symbol is determined based on n4= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and in the third period and the fourth period, the terminal is configured not to send DCI formats of PUSCH, PUCCH, physical Random access channel (Physical Random ACCESS CHANNEL, PRACH) or SRS, so as to constrain dynamically scheduled uplink transmission, thus effectively solving the problem that uplink and downlink collision occurs on the terminal side due to unreasonable transmission configuration of the base station.

In another possible scenario, the uplink transmission is semi-static configured and the downlink reception is semi-static configured.

Illustratively, in this possible scenario, four cases are included, one in which the uplink and downlink reception are terminal-specific semi-static configurations, namely, UE-DEDICATED SEMI-static UL configuration and UE-DEDICATED SEMI-static DL configuration, another in which the uplink is terminal-specific semi-static configuration and the downlink reception is Cell-level semi-static configuration, namely, UE-DEDICATED SEMI-static UL configuration and Cell-SPECIFIC SEMI-static DL configuration, and yet another in which the uplink is Cell-level semi-static configuration and the downlink reception is terminal-specific semi-static configuration, namely, cell-SPECIFIC SEMI-static UL configuration and UE-DEDICATED SEMI-static DL configuration, and yet another in which the uplink and downlink reception are Cell-level semi-static configurations, namely, cell-SPECIFIC SEMI-static UL configuration and Cell-SPECIFIC SEMI-static DL configuration.

For example, in one case, both the uplink transmission and the downlink reception are terminal-specific semi-static configurations. When the target period is determined based on the timing advance, the target period may be determined based on uplink attribute information, downlink attribute information, and the timing advance, where the attribute information includes priority, and/or configuration flexibility.

In the embodiment of the present application, for example, when the uplink transmission and the downlink reception are both semi-static configurations dedicated to the terminal, the attribute information includes a priority, and the target period may be determined according to the priorities and the timing advance of the uplink transmission and the downlink reception.

Illustratively, in an embodiment of the present application, the priority is configured by at least one of:

Semi-static configuration of radio resource control (Radio Resource Control, RRC) parameters;

Dynamic configuration of downlink control information;

a medium access control element (MEDIA ACCESS Control Control Element, MAC CE) configuration.

For example, in the embodiment of the present application, the configuration flexibility may be time-domain period configuration flexibility, time-domain position configuration flexibility, or the like, which may be specifically set according to actual needs, where the embodiment of the present application is not limited further.

And when the uplink transmission and the downlink reception are both in the cell-level semi-static configuration, or the uplink transmission is the dedicated semi-static configuration of the terminal and the downlink reception is the cell-level semi-static configuration, the attribute information comprises configuration flexibility, and the target period can be determined according to the configuration flexibility and the timing advance of the uplink transmission and the downlink reception.

For example, when determining the target period based on the attribute information of the uplink transmission, the attribute information of the downlink reception, and the timing advance, the target transmission corresponding to the higher priority may be determined from the uplink transmission and the downlink reception based on the priority of the uplink transmission and the priority of the downlink reception, and then the target period may be determined based on the timing advance of the target transmission.

It can be understood that if the priority of the uplink transmission is higher than the priority of the downlink reception, the target transmission is the uplink transmission, and conversely, if the priority of the uplink transmission is lower than the priority of the downlink reception, the target transmission is the downlink reception.

In an example, when determining the target period based on the timing advance of the target transmission, the fifth period before the start symbol is transmitted may be determined based on the timing advance of the uplink transmission, a preset timing threshold offset value, and a transition time of the terminal from downlink reception to uplink transmission, and the sixth period after the end of the symbol is determined based on the timing advance of the uplink transmission, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception, where the target period includes the fifth period and the sixth period, and the transmission operation is downlink reception.

The fifth period may be understood as a ambiguity period before the terminal transmits the start symbol, and the sixth period may be understood as a ambiguity period after the terminal transmits the end symbol, during which the network device configures the terminal not to perform downlink reception, in other words, configures the terminal to perform downlink reception outside of the two ambiguity periods.

For example, the fifth period may be denoted as N5, the sixth period may be denoted as N6, the fifth period before the terminal transmits the start symbol may be determined based on n5= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the sixth period after the terminal transmits the symbol is determined based on n6= reported TA-offsetThresholdTAr17+n _TX-RX*T_C.

It can be seen that, in the case that both the uplink transmission and the downlink reception are configured in a semi-static manner and the priority of the uplink transmission is higher than that of the downlink reception, the network device can determine the fifth period before the terminal transmits the start symbol based on the timing advance of the uplink transmission, the preset timing threshold offset value and the conversion time of the terminal from the downlink reception to the uplink transmission, determine the sixth period after the terminal transmits the symbol is finished based on the timing advance of the uplink transmission, the timing threshold offset value and the conversion time of the terminal from the uplink transmission to the downlink reception, and configure the terminal not to perform the downlink reception in the fifth period and the sixth period so as to restrict the downlink reception with lower priority, thereby effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Example 3

In the case that both uplink transmission and downlink reception are Semi-static configuration dedicated to a terminal, that is, semi-static UL configuration and Semi-static DL configuration, if the priority of uplink transmission is higher than that of downlink reception, in order to avoid uplink and downlink collision at the terminal side, it is necessary to restrict downlink reception with a lower priority, which specifically includes:

If the higher-layer configuration terminal sends the dedicated higher-layer parameter configuration of the terminal on a group of symbols, a fifth period before the initial symbol is sent can be determined based on n5= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, a sixth period after the end of the symbol is sent is determined based on n6= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and the dedicated higher-layer parameter configuration of the UE is not received by the configuration terminal in the fifth period and the sixth period, so that the downlink reception with lower priority is restrained, and the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station can be effectively solved.

In an example, when determining the target period based on the timing advance of the target transmission, the seventh period before the reception of the start symbol may be determined based on the timing advance of the downlink reception, a preset timing threshold offset value, and a transition time of the terminal from uplink to downlink reception, and the eighth period after the end of the reception symbol may be determined based on the timing advance of the downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink to uplink reception, wherein the target period includes the seventh period and the eighth period, and the transmission operation is uplink transmission.

The seventh period may be understood as a ambiguity period before the terminal receives the start symbol, and the eighth period may be understood as a ambiguity period after the terminal receives the end symbol, during which the network device configures the terminal not to perform uplink transmission, in other words, the network device reconfigures the terminal to perform uplink transmission outside of the two ambiguity periods.

Illustratively, the seventh period may be denoted as N7, the eighth period may be denoted as N8, the seventh period may be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and the eighth period may be determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C.

It can be seen that, when the uplink transmission and the downlink reception are configured in a semi-static manner and the priority of the uplink transmission is lower than that of the downlink reception, the network device can determine the seventh period before the initial symbol is received based on the timing advance of the downlink reception, the preset timing threshold offset value and the conversion time of the terminal from the uplink transmission to the downlink reception, determine the eighth period after the end of the received symbol based on the timing advance of the downlink reception, the timing threshold offset value and the conversion time of the terminal from the downlink reception to the uplink transmission, and configure the terminal not to perform the uplink transmission in the seventh period and the eighth period so as to restrict the uplink transmission with lower priority, thereby effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Example 4

Under the condition that the uplink transmission and the downlink reception are Semi-static configuration specific to the terminal, namely Semi-static UL configuration and Semi-static DL configuration, if the priority of the uplink transmission is lower than that of the downlink reception, in order to avoid uplink and downlink collision at the terminal side, the method specifically comprises the following steps:

If the higher-layer configured terminal receives the dedicated higher-layer parameter configuration of the terminal on a group of symbols, a seventh period before receiving the initial symbol can be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, an eighth period after receiving the symbol is ended can be determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the dedicated higher-layer parameter configuration of the UE is not sent by the configured terminal in the seventh period and the eighth period so as to restrict the uplink transmission with lower priority, thus effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

For example, when determining the target period based on the attribute information of the uplink transmission, the attribute information of the downlink reception, and the timing advance, the target transmission corresponding to the lower configuration flexibility may be determined from the uplink transmission and the downlink reception based on the configuration flexibility of the uplink transmission and the configuration flexibility of the downlink reception, and the target period may be determined based on the timing advance of the target transmission.

In general, the configuration flexibility of the terminal-specific semi-static configuration is higher than that of the cell-level semi-static configuration.

It may be understood that in the embodiment of the present application, if the uplink transmission is the dedicated semi-static configuration of the terminal, the downlink reception is the cell-level semi-static configuration, and the target transmission is the uplink transmission, if the uplink transmission is the cell-level semi-static configuration, the downlink reception is the dedicated semi-static configuration of the terminal, the target transmission may be the downlink reception or the uplink transmission, and may be specifically determined by the terminal autonomously, and if the uplink transmission and the downlink reception are both the cell-level semi-static configuration, the target transmission may be the downlink reception.

For example, in another case, the uplink transmission is a terminal-specific semi-static configuration and the downlink reception is a cell-level semi-static configuration. In view of the fact that the configuration flexibility of the dedicated semi-static configuration of the terminal is higher than that of the cell-level semi-static configuration, the target transmission is downlink reception, and the target period can be determined based on the timing advance of the downlink reception.

Example 5

In the case that the uplink transmission is a terminal-specific semi-static configuration, and the downlink reception is a Cell-level semi-static configuration, that is, UE-DEDICATED SEMI-static UL configuration and Cell-SPECIFIC SEMI-static DL configuration, in view of the fact that the flexibility of the configuration of the terminal-specific semi-static configuration is higher than that of the Cell-level semi-static configuration, in order to avoid uplink and downlink collision at the terminal side, uplink transmission is required to be restricted, which specifically includes:

If the higher-layer configured terminal receives the Type-0/0A/1/2-PDCCH Common search space (Common SEARCH SPACE, CSS) set configuration on a group of symbols, a seventh period before receiving the initial symbol can be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, an eighth period after receiving the symbol is finished can be determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the configured terminal does not send the Type-0/0A/1/2-PDCCH CSS set configuration in the seventh period and the eighth period so as to restrict uplink transmission, so that the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station can be effectively solved.

For example, in yet another case, the uplink transmission is a cell-level semi-static configuration and the downlink reception is a terminal-specific semi-static configuration. In view of the fact that the Cell-SPECIFIC SEMI-static UL configuration only contains Valid random access opportunities (Randomaccess Channel Occasion, RO), the existing Valid RO and SPECIFIC SEMI-static UL configuration, or Valid RO and Dynamic UL configuration, may be referred to, and the terminal may select uplink transmission, i.e. determine uplink transmission as target transmission, or may also select downlink reception, i.e. determine downlink reception as target transmission, which is receivable for the network device, so that the processing rules of Valid RO and SPECIFIC SEMI-static UL configuration, or Valid RO and Dynamic UL configuration in the existing terrestrial system may be continued to solve the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Illustratively, in yet another case, both the uplink transmission and the downlink reception are semi-static configurations at the cell level. In this case, a typical example is that the Cell-SPECIFIC SEMI-static DL signal is a synchronization signal block (Synchronization Signal Block, SSB) and Type0/0A/1/2-CSS PDCCH, so in the embodiment of the present application, the case of SSB and Valid RO may refer to the existing SSB and SPECIFIC SEMI-static UL configuration or the processing rule of SSB and Dynamic UL configuration, and the case of Type0/0A/1/2-CSS PDCCH and Valid RO may refer to the existing Valid RO and SPECIFIC SEMI-static UL configuration or the processing rule of Valid RO and Dynamic UL configuration, which are not repeated herein, so as to solve the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

For example, in the case of SSB and SPECIFIC SEMI-static UL configurations, or SSB and Dynamic UL configurations, the network device may determine a period of time before receiving the start symbol of the SSB signal and a period of time after receiving the symbol of the SSB signal, and the specific implementation of which is similar to the specific implementation of the seventh period of time before determining to receive the start symbol and the eighth period of time after receiving the symbol is finished, which are described in the above related description, and the embodiments of the present application will not be repeated herein. After two time periods are determined respectively, the terminal is configured not to execute uplink transmission in the two time periods so as to restrict the uplink transmission, thereby effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Example 6

In the case of SSB and SPECIFIC SEMI-static UL configuration, or SSB and Dynamic UL configuration, if the terminal indicates that there is a synchronization signal (Synchronization Signal, SS) or a physical broadcast channel block (Physical Broadcast Channel Block, PBCH) on a group of symbols of an active DL Bandwidth Part (BWP) through SSB-PositionsInBurst in a system information block (System Information Block, SIB) 1, servingCellConfigCommon, or through NonCellDefiningSSB, a seventh period before the start symbol is indicated can be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and an eighth period after the end of the indication symbol is determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the terminal is configured not to detect a DCI format for scheduling PUSCH or PUCCH or SRS transmission in the seventh and eighth periods, so that uplink transmission is constrained, which can effectively solve the problem that uplink and downlink collision occurs on the terminal side due to unreasonable transmission configuration of the base station.

If the terminal indicates that SS or PBCH exists on a group of symbols activating DL BWP through ssb-PositionsInBurst or NonCellDefiningSSB in SIB1, servingCellConfigCommon, a seventh period before the start symbol is indicated can be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, an eighth period after the end of the indication symbol is determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and PUSCH or PUCCH or SRS configured by high-level parameters is not transmitted by the terminal in the seventh period and the eighth period, so as to restrict uplink transmission, thus effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

In yet another possible scenario, the uplink transmission is Dynamic scheduling and the downlink reception is also Dynamic scheduling, i.e., dynamic UL scheduling and DYNAMIC DL scheduling.

For example, when the uplink transmission is dynamically scheduled and the downlink reception is dynamically scheduled, the target period may be determined based on the timing advance of the target transmission, and the target period may be determined based on the timing advance of the target transmission.

Dynamic configuration of downlink control information;

Example 7

Under the condition that both uplink transmission and downlink reception are dynamic scheduling, if the priority of the uplink transmission is higher than the priority of the downlink reception, in order to avoid uplink and downlink collision at the terminal side, the downlink reception with lower priority needs to be constrained, which specifically includes:

If the terminal detects the DCI format on a set of symbols, a fifth period before the start symbol is transmitted may be determined based on n5= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and a sixth period after the end of the symbol is determined based on n6= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and the terminal is configured not to receive the DCI format in the fifth period and the sixth period, so as to restrict downlink reception with a lower priority, so that the problem of uplink and downlink collision on the terminal side due to unreasonable transmission configuration of the base station can be effectively solved.

For example, the seventh period may be denoted as N7, the eighth period may be denoted as N8, the seventh period before the reception of the start symbol may be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and the eighth period after the end of the reception of the symbol may be determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C.

It can be seen that, when the uplink transmission and the downlink reception are configured in a semi-static manner and the priority of the uplink transmission is lower than that of the downlink reception, the network device can determine the seventh period before the initial symbol is received based on the timing advance of the downlink reception, the preset timing threshold offset value and the conversion time of the terminal from the uplink transmission to the downlink reception, determine the eighth period after the end of the received symbol based on the timing advance, the timing threshold offset value and the conversion time of the terminal from the downlink reception to the uplink transmission, and configure the terminal not to perform the uplink transmission in the seventh period and the eighth period so as to restrict the uplink transmission with lower priority, thereby effectively solving the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

Example 8

Under the condition that the uplink transmission and the downlink reception are dedicated Semi-static configuration of the terminal, namely Semi-static UL and Semi-static DL, if the priority of the uplink transmission is lower than that of the downlink reception, in order to avoid uplink and downlink collision at the terminal side, the constraint on the uplink transmission with lower priority is needed, which specifically includes:

If the terminal detects the DCI format received on a set of symbols, a seventh period before receiving the initial symbol may be determined based on n7= reported TA-offsetThresholdTAr17+n _TX-RX*T_C, and an eighth period after receiving the symbol ends may be determined based on n8= reported TA-offsetThresholdTAr17+n _RX-TX*T_C, and the terminal may be configured to not transmit the DCI format in the seventh period and the eighth period, so as to restrict uplink transmission with a lower priority, which may effectively solve the problem of uplink and downlink collision on the terminal side caused by unreasonable transmission configuration of the base station.

It can be understood that in the embodiment of the present application, when determining the period before transmitting the start symbol or the period before receiving the start symbol, if the calculated period value is greater than 0, the period value is determined to be the calculated period value, and if the calculated period value is less than 0, the period value is determined to be 0, which may be specifically set according to actual needs.
