[0093] Figure 1 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. Specifically, the wireless communication system includes a terminal 11 and a network side device 12.

[0094] ​The terminal 11 can be a terminal-side device such as a mobile phone, a Tablet Personal Computer, a Laptop Computer, a notebook computer, a Personal Digital Assistant (PDA), a palmtop computer, a netbook, an Ultra-mobile Personal Computer (UMPC), a Mobile Internet Device (MID), an Augmented Reality (AR) device, a Virtual Reality (VR) device, a robot, a wearable device, a flight vehicle, a Vehicle User Equipment (VUE), a shipboard device, a Pedestrian User Equipment (PUE), a smart home (a home device with a wireless communication function, such as a refrigerator, a television, a washing machine, or furniture), a game console, a Personal Computer (PC), a kiosk, or a self-service machine. The wearable device includes a smart watch, a smart bracelet, a smart earphone, smart glasses, smart jewelry (a smart bracelet, a smart necklace, a smart ring, a smart necklace, a smart anklet, a smart necklace, and the like), a smart wristband, smart clothing, and the like. The vehicle-mounted device can also be referred to as a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, or a vehicle-mounted unit. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0095] The network side device 12 can include an access network device. Optionally, the access network device can also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc. The base station can be referred to as a node B (NB), an evolved node B (eNB), a next generation node B (gNB), a new radio node B (NR node B), an access point, a relay base station (RBS), a serving base station (SBS), a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a home node B (HNB), a home evolved node B, a transmit / receive point (TRP) or some other suitable term in the art, as long as the same technical effect is achieved. The base station is not limited to a specific technical term as long as the same technical effect is achieved. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0096] For better understanding of the embodiments of the present application, the related technologies of the present application are described.

[0097] Mobile communication systems need to adapt to more diverse scenarios and service requirements, for example, the main scenarios of 5G include enhanced mobile broadband (eMBB), ultra-reliable and low latency communication (URLLC), massive machine type of communication (mMTC), which puts forward the requirements of high reliability, low latency, large bandwidth, wide coverage and the like for the system. For different application scenarios, the transmission bandwidth required by the terminal is different. In NR, the base station can schedule the terminal to transmit on different bandwidth parts according to the needs.

[0098] In NR, the network side configures one or more bandwidth parts (BWP) for the UE to perform data transmission, and the BWP is a continuous resource in the frequency domain. The UE realizes dynamic bandwidth change by activating different BWPs. As shown in FIG. 2, at the first time, the traffic volume of the UE is large, and the UE activates a large bandwidth (BWP1); at the second time, the traffic volume of the UE is small, and the UE activates a small bandwidth (BWP2), which can meet the basic communication requirements; at the third time, the network side detects that there is a large range of frequency selective fading in the bandwidth of BWP1, or the resources in the frequency range of BWP2 are relatively scarce, so the UE is instructed to activate a new bandwidth (BWP3). Each BWP can correspond to different configuration parameters, including subcarrier spacing, BWP position and bandwidth, cyclic prefix (CP), and the like.

[0099] In order to better understand the embodiments of the present application, the SBFD related to the present application is described.

[0100] When deploying a traditional cellular network, based on the available spectrum, service characteristics and the like, duplex modes such as frequency division duplex (FDD), time division duplex (TDD) and the like can be used. When FDD is used, uplink transmission and downlink transmission are located at different frequency points, and the two do not interfere with each other, and can be performed at the same time. When TDD is used, uplink transmission and downlink transmission are located at the same frequency point, and are staggered in time division mode. The two duplex modes have advantages and disadvantages.

[0101] In order to more flexibly utilize limited spectrum resources, to dynamically match service requirements, to improve resource utilization efficiency, and to improve the performance of uplink coverage, latency and the like of data transmission, a flexible duplex mode is proposed.

[0102] Network side full duplex

[0103] From the perspective of the network side, at the same time, uplink transmission and downlink transmission can be carried out in different frequency domain subbands. In order to avoid interference between uplink and downlink, a certain guard band (also referred to as guard interval) can be left between frequency domain subbands corresponding to different transmission directions (for example, uplink subband and downlink subband). It is also referred to as network side subband full duplex.

[0104] Terminal side half duplex or full duplex

[0105] When the terminal side supports half duplex, at the same time, only uplink transmission or downlink transmission can be carried out, and both cannot be carried out at the same time. It can be understood that in this case, uplink transmission and downlink transmission of the network side at the same time can only be for different terminals.

[0106] When the terminal side supports full duplex, similar to the network side, at the same time, uplink transmission and downlink transmission can be carried out in different frequency domain subbands. It is also referred to as terminal side subband full duplex.

[0107] FIG. 3 gives a schematic diagram of the above flexible duplex mode. The network side divides the frequency domain of a single carrier into three subbands in a part of downlink symbols, wherein the two sides of the carrier are downlink subbands, and the center is an uplink subband, so as to reduce interference on adjacent carriers. Except that the resources of the uplink and downlink subbands are guard bands. For the network side SBFD, the guard band is generally 2-3 PRBs. For the terminal side SBFD, considering the terminal performance, the guard band is generally about 30 MHz, which will seriously affect the resource utilization. In FIG. 3, if it is network side subband full duplex, in the third time slot, UE1 and UE2 carry out uplink transmission and downlink reception respectively, and the base station simultaneously receives data of UE1 and transmits data to UE2. If it is terminal side subband full duplex, UE1 can simultaneously carry out uplink transmission and downlink reception in the third time slot, and the base station simultaneously receives and transmits uplink and downlink data of UE1. In FIG. 3, “D” represents downlink, “U” represents uplink, and “F” represents flexibility, which is the TDD uplink and downlink configuration configured by the network side device.

[0108] In order to better understand the embodiments of the present application, the problems solved by the present application are described.

[0109] No matter network side sub-band full duplex or terminal side sub-band full duplex, at least one of semi-static configured uplink sub-band, guard band, and downlink sub-band will be configured. For a terminal supporting terminal side sub-band full duplex, considering that the terminal does not have the need to simultaneously transmit and receive data at every moment, and the guard band of terminal side sub-band full duplex is relatively large, when the terminal only performs single direction transmission, the actual available resources are much less than those in half duplex mode or network side sub-band full duplex.

[0110] Based on the above technical problem, in order to improve resource utilization, the embodiments of the present application allow the terminal supporting terminal side sub-band full duplex to use smaller guard band or half duplex mode or network side sub-band full duplex for transmission when the situation allows, that is, to avoid reserving unnecessary guard band resources.

[0111] The wireless communication method provided by the embodiments of the present application will be described in detail in combination with some embodiments and application scenarios thereof, with reference to the accompanying drawings.

[0118] The embodiments of the present application do not limit the execution order of S230 and S240. For example, S230 can be executed first and then S240 can be executed. For another example, S240 can be executed first and then S230 can be executed. For yet another example, S230 and S240 can be executed simultaneously.

When the terminal supports terminal-side sub-band full-duplex and is configured with at least one terminal-side sub-band full-duplex frequency domain resource configuration, and / or the terminal is configured with at least one network-side sub-band full-duplex frequency domain resource configuration, for the time domain unit of terminal-side sub-band full-duplex, the terminal can select the first frequency domain resource configuration or the second frequency domain resource configuration of terminal-side sub-band full-duplex (at this time, both the network side and the terminal side are in sub-band full-duplex mode), or the terminal can select the network-side sub-band full-duplex frequency domain resource configuration (network-side sub-band full-duplex, terminal-side half-duplex), or the terminal can select the uplink BWP and / or downlink BWP corresponding frequency domain resource configuration (both the network side and the terminal side are in half-duplex mode). When the terminal selects the network-side sub-band full-duplex frequency domain resource configuration or the uplink BWP and / or downlink BWP corresponding frequency domain resource configuration, it is equivalent to the terminal switching to half-duplex mode, or the system switching to network-side sub-band full-duplex mode or half-duplex mode. The terminal selecting the frequency domain resource configuration can also be referred to as the terminal switching / updating the frequency domain resource configuration. Optionally, the downlink sub-band, uplink sub-band, or guard band of the first frequency domain resource configuration and the second frequency domain resource configuration are different in size. Optionally, the guard band of the first frequency domain resource configuration is smaller than the guard band of the second frequency domain resource configuration. The terminal can autonomously select the frequency domain resource configuration or select the corresponding frequency domain resource configuration based on the base station indication.

[0149] In the embodiments of the present application, when the frequency domain resource selected by the terminal is configured as the frequency domain resource configuration of terminal-side sub-band full duplex, the terminal can simultaneously receive and transmit on the corresponding downlink sub-band (DL subband) and uplink sub-band (UL subband).

[0150] In the embodiments of the present application, when the frequency domain resource selected by the terminal is configured as the frequency domain resource configuration of network-side sub-band full duplex, or the frequency domain resource selected by the terminal is configured as the frequency domain resource configuration corresponding to the uplink BWP, or the frequency domain resource selected by the terminal is configured as the frequency domain resource configuration corresponding to the downlink BWP, the terminal only receives or only transmits on the corresponding downlink sub-band (DL subband), downlink BWP, or uplink sub-band (UL subband), uplink BWP.

[0151] In some embodiments, if the first information includes whether the first object and the second object exist simultaneously in the first time domain unit, the S230 specifically includes:

[0152] If the first object and the second object exist simultaneously in the first time domain unit, the terminal selects the first target frequency domain resource configuration; or

[0153] If the first object and the second object exist simultaneously in the first time domain unit, and the frequency domain resource of the uplink transmission in the first time domain unit is greater than or equal to M1 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; or

[0155] If the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission in the first time domain unit and the downlink sub-band is less than or equal to M3 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; or

[0156] If the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission and the frequency domain resource of the downlink transmission in the first time domain unit is less than or equal to M3 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; or,

[0157] If the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission and the downlink sub-band configured in the first time domain unit is less than or equal to M4 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; or,

[0158] If the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission and the frequency domain resource of the downlink transmission configured in the first time domain unit is less than or equal to M4 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; or,

[0159] If only the first object exists in the first time domain unit, or only the second object exists in the first time domain unit, the terminal selects the second target frequency domain resource configuration; it is pointed out here that "only" is relative to the first object and the second object, and its meaning is that one of the first object and the second object exists in the first time domain unit.

[0160] Wherein, M1, M2, M3 and M4 are positive integers.

[0161] In this embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to whether the first object and the second object exist simultaneously in the first time domain unit, so that the terminal supporting the terminal side sub-band full duplex can flexibly select the frequency domain resource configuration, can maximize the resource utilization, reduce the interference influence, and improve the system performance.

[0162] Specifically, for example, in the case where the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to whether the first object and the second object exist simultaneously in the first time domain unit, the first target frequency domain resource configuration is the frequency domain resource configuration of the terminal side sub-band full duplex, and the second target frequency domain resource configuration is one of the following: the frequency domain resource configuration of the network side sub-band full duplex, the frequency domain resource configuration corresponding to the uplink BWP, and the frequency domain resource configuration corresponding to the downlink BWP.

[0163] Optionally, the value of M1 can be agreed by a protocol, or the value of M1 can be configured by a network side, or the value of M1 is related to a capability of the terminal, or the value of M1 is determined based on the capability of the terminal.

[0164] Optionally, the value of M2 can be agreed by a protocol, or the value of M2 can be configured by a network side, or the value of M2 is related to a capability of the terminal, or the value of M2 is determined based on the capability of the terminal.

[0165] Optionally, the value of M3 can be agreed by a protocol, or the value of M3 can be configured by a network side, or the value of M3 is related to a capability of the terminal, or the value of M3 is determined based on the capability of the terminal.

[0166] Optionally, the value of M4 can be agreed by a protocol, or the value of M4 can be configured by a network side, or the value of M4 is related to a capability of the terminal, or the value of M4 is determined based on the capability of the terminal.

[0167] For example, the first time domain unit can be t1 symbols, or the first time domain unit can be t1 slots, or the first time domain unit can be t1 subframes, or the first time domain unit can be t2 milliseconds; where t1 is an integer greater than or equal to 1, and t2>0.

[0168] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the frequency domain resource of the uplink transmission in the first time domain unit is greater than or equal to M1 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the frequency domain resource of the uplink transmission configured in the first time domain unit is less than M1 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0169] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the frequency domain resource of the uplink transmission configured in the first time domain unit is greater than or equal to M2 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the frequency domain resource of the uplink transmission configured in the first time domain unit is less than M2 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0170] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission in the first time domain unit and the downlink sub-band is less than or equal to M3 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission in the first time domain unit and the downlink sub-band is greater than M3 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0171] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission in the first time domain unit and the frequency domain resource of the downlink transmission is less than or equal to M3 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission in the first time domain unit and the frequency domain resource of the downlink transmission is greater than M3 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0172] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission configured in the first time domain unit and the downlink sub-band is less than or equal to M4 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission configured in the first time domain unit and the downlink sub-band is greater than M4 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0173] For example, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission and the frequency domain resource of the downlink transmission configured in the first time domain unit is less than or equal to M4 frequency domain units, the terminal selects the second target frequency domain resource configuration, or the terminal selects the second frequency domain resource configuration in the first target frequency domain resource configuration; and / or, if the first object and the second object exist simultaneously in the first time domain unit, and the interval between the frequency domain resource of the uplink transmission and the frequency domain resource of the downlink transmission configured in the first time domain unit is greater than M4 frequency domain units, the terminal selects the first target frequency domain resource configuration, or the terminal selects the first frequency domain resource configuration in the first target frequency domain resource configuration.

[0174] In some embodiments, if the first information includes whether the first object and the second object exist simultaneously in the first time domain unit, the network side device should at least satisfy the time for the terminal to process the downlink assignment, prepare data, switch the frequency domain resource configuration, and the corresponding antenna configuration, etc. between the cross-slot scheduling, the downlink assignment and the downlink data for the downlink transmission.

[0175] In some embodiments, if the first information includes whether the first object and the second object exist simultaneously in the first time domain unit, the S230 specifically includes:

[0176] The terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to whether the first object and the second object exist simultaneously in the first time domain unit on at least N1 time domain units before the first time domain unit.

[0177] Wherein, N1 is a positive integer.

[0178] Optionally, the N1 time domain units at least satisfy the time for the terminal to process information or switch configuration, etc. For example, the N1 time domain units are T proc .

[0179] Optionally, the value of N1 can be agreed by the protocol, or the value of N1 can be configured by the network side, or the value of N1 is related to the capability of the terminal or the value of N1 is determined based on the capability of the terminal.

[0180] In some embodiments, in the case that the first information includes the first indication information, the S230 specifically can include:

[0181] If the transmission direction on the second time domain unit indicated by the first indication information is flexible, the terminal selects the first target frequency domain resource configuration; and / or,

[0182] If the transmission direction on the second time domain unit indicated by the first indication information is uplink transmission or downlink transmission, the terminal selects the second target frequency domain resource configuration.

[0183] In the embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the first indication information, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0184] For example, the second time domain unit can be t3 symbols, or the first time domain unit can be t3 slots, or the first time domain unit can be t3 subframes, or the first time domain unit can be t4 milliseconds; wherein t3 is an integer greater than or equal to 1, and t4>0.

[0185] Optionally, the first indication information can be carried by at least one of the following:

[0186] Time Division Duplex (TDD) uplink-downlink (UL-DL) configuration;

[0187] Slot format indication (SFI);

[0188] Transmission direction indication dedicated signaling.

[0189] For example, in the case that the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the first indication information, the first target frequency domain resource configuration is the frequency domain resource configuration of terminal-side sub-band full duplex, and the second target frequency domain resource configuration is one of the following: network-side sub-band full duplex frequency domain resource configuration, uplink BWP corresponding frequency domain resource configuration, and downlink BWP corresponding frequency domain resource configuration.

[0190] In some embodiments, if the terminal selects the second target frequency domain resource configuration based on the first indication information, and the first object and the second object exist simultaneously in the second time domain unit, the terminal switches the selected frequency domain resource configuration from the second target frequency domain resource configuration to the first target frequency domain resource configuration; and / or,

[0191] If the terminal selects the first target frequency domain resource configuration based on the first indication information, and only the first object exists in the second time domain unit or only the second object exists in the second time domain unit, the terminal switches the selected frequency domain resource configuration from the first target frequency domain resource configuration to the second target frequency domain resource configuration.

[0192] In the embodiment, after the terminal selects the corresponding frequency domain resource configuration according to the first indication information, the terminal can further select the frequency domain resource configuration according to whether the first object and the second object exist in the second time domain unit at the same time, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0193] In some embodiments, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to whether the first object and the second object exist in the second time domain unit at the same time on at least N2 time domain units before the second time domain unit.

[0194] Wherein, N2 is a positive integer.

[0195] Optionally, the N2 time domain units at least meet the time of processing information or switching configuration of the terminal. For example, the N2 time domain units are T proc .

[0196] Optionally, the value of N2 can be agreed by a protocol, or the value of N2 can be configured by the network side, or the value of N2 is related to the capability of the terminal or the value of N2 is determined based on the capability of the terminal.

[0197] In some embodiments, in the case that the first information includes the position information of the terminal, the above S230 can specifically include:

[0198] If the terminal is located in the first range, the terminal selects the first target frequency domain resource configuration; and / or,

[0199] If the terminal is located outside the first range or the terminal is located in the second range, the terminal selects the second target frequency domain resource configuration.

[0200] Wherein, the first range is an area with a distance less than or equal to X meters from the network side device (such as a base station), and the second range is an area with a distance greater than or equal to X meters from the network side device (such as a base station), X>0.

[0201] In the embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the location information of the terminal, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0202] Optionally, the value of X can be agreed by a protocol, or the value of X can be configured by the network side, or the value of X is related to the capability of the terminal or the value of X is determined based on the capability of the terminal.

[0203] For example, in the case where the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the location information of the terminal, the first target frequency domain resource configuration is a frequency domain resource configuration of terminal-side sub-band full duplex, and the second target frequency domain resource configuration is one of the following: a frequency domain resource configuration of network-side sub-band full duplex, a frequency domain resource configuration corresponding to an uplink BWP, and a frequency domain resource configuration corresponding to a downlink BWP.

[0204] In some embodiments, if the first information includes the signal quality information measured by the terminal, the S230 can specifically include the following steps.

[0205] If the CSI, RSRP, or RSRQ measured by the terminal is greater than a first threshold, or the RSSI measured by the terminal is less than a second threshold, the terminal selects the first target frequency domain resource configuration; and / or,

[0206] If the CSI, RSRP, or RSRQ measured by the terminal is less than or equal to the first threshold, or the RSSI measured by the terminal is greater than or equal to the second threshold, the terminal selects the second target frequency domain resource configuration.

[0207] In the embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the signal quality information measured by the terminal, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0208] Optionally, the first threshold can be agreed by a protocol, or the first threshold can be configured by the network side, or the first threshold is related to the capability of the terminal or the first threshold is determined based on the capability of the terminal.

[0209] Optionally, the second threshold can be agreed by a protocol, or the second threshold can be configured by the network side, or the second threshold is related to the capability of the terminal or the second threshold is determined based on the capability of the terminal.

[0210] For example, in a case where the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the signal quality information measured by the terminal, the first target frequency domain resource configuration is a frequency domain resource configuration supporting terminal-side sub-band full duplex, and the second target frequency domain resource configuration is one of the following: a frequency domain resource configuration supporting network-side sub-band full duplex, a frequency domain resource configuration corresponding to an uplink BWP, and a frequency domain resource configuration corresponding to a downlink BWP.

[0211] In some embodiments, if the frequency domain resource configuration selected by the terminal is inconsistent with the currently used frequency domain resource configuration, the terminal uses the frequency domain resource configuration selected by the terminal after at least P1 time domain units after reporting the signal quality information measured by the terminal, where P1 is a positive integer.

[0212] Optionally, the P1 time domain units are time required for the terminal to perform frequency domain resource configuration switching.

[0213] Optionally, the value of P1 can be agreed by a protocol, or the value of P1 can be configured by the network side, or the value of P1 is related to the capability of the terminal or the value of P1 is determined based on the capability of the terminal.

[0214] For example, if the selected frequency domain resource configuration is inconsistent with the current frequency domain resource configuration, the terminal uses the selected frequency domain resource configuration after at least P1 time after reporting the CSI, RSRP, RSRQ or RSSI. Optionally, the terminal selects the frequency domain resource configuration according to the indication of the network side device after reporting the CSI, RSRP, RSRQ or RSSI.

[0215] In some embodiments, in a case where the first information includes the second indication information, the S230 can specifically include:

[0216] If the rank or the number of layers indicated by the second indication information is less than a third threshold value, the terminal selects the first target frequency domain resource configuration; and / or,

[0217] If the rank or the number of layers indicated by the second indication information is greater than or equal to the third threshold value, the terminal selects the second target frequency domain resource configuration.

[0218] In this embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the second indication information, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0219] It should be noted that considering that the antenna configuration of the terminal may be divided into two parts when the terminal performs sub-band full duplex transmission, one part is used as a transmitting antenna and the other part is used as a receiving antenna, compared with half duplex transmission using all antennas for receiving or transmitting, the number of layers that the terminal can simultaneously transmit will be reduced, therefore, the terminal can select the frequency domain resource configuration according to the rank size or the number of layers indicated by the network side device.

[0220] For example, in a case where the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the second indication information, the first target frequency domain resource configuration is a frequency domain resource configuration of terminal side sub-band full duplex, and the second target frequency domain resource configuration is one of the following: a frequency domain resource configuration of network side sub-band full duplex, a frequency domain resource configuration corresponding to an uplink BWP, and a frequency domain resource configuration corresponding to a downlink BWP.

[0221] Optionally, the second indication information can be carried by at least one of the following:

[0222] Downlink Control Information (DCI), Radio Resource Control (RRC), and Media Access Control Control Element (MAC CE).

[0223] Optionally, the third threshold value can be determined by a protocol, or the third threshold value can be configured by the network side, or the third threshold value is related to the capability of the terminal, or the third threshold value is determined based on the capability of the terminal.

[0224] In some embodiments, in a case where the first information includes the first timer and / or the second timer, the above S230 can specifically include:

[0225] When the terminal selects the first target frequency domain resource configuration, the terminal starts the first timer, and when the first timer expires, the terminal switches the selected frequency domain resource configuration from the first target frequency domain resource configuration to the second target frequency domain resource configuration; and / or,

[0226] When the terminal selects the second target frequency domain resource configuration, the terminal starts the second timer, and when the second timer expires, the terminal switches the selected frequency domain resource configuration from the second target frequency domain resource configuration to the first target frequency domain resource configuration.

[0227] In the embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the first timer and / or the second timer, so that the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0228] For example, when the terminal selects the first target frequency domain resource configuration, the terminal starts the first timer, and after the first timer expires, the terminal switches the selected frequency domain resource configuration from the first target frequency domain resource configuration to the second target frequency domain resource configuration, and starts the second timer; after the second timer expires, the terminal switches the selected frequency domain resource configuration from the second target frequency domain resource configuration to the first target frequency domain resource configuration, and starts the first timer; and so on.

[0229] Optionally, the related information (such as the starting time, the time length, the restart condition, etc.) of the first timer is configured by the network side, or the related information (such as the starting time, the time length, the restart condition, etc.) of the first timer is related to the capability of the terminal, or the related information (such as the starting time, the time length, the restart condition, etc.) of the first timer is determined based on the capability of the terminal.

[0230] Optionally, the related information (such as the starting time, the time length, the restart condition, etc.) of the second timer is configured by the network side, or the related information (such as the starting time, the time length, the restart condition, etc.) of the second timer is related to the capability of the terminal, or the related information (such as the starting time, the time length, the restart condition, etc.) of the second timer is determined based on the capability of the terminal.

[0231] For example, in the case that the terminal selects the frequency domain resource configuration based on the first timer and / or the second timer, the first target frequency domain resource configuration is one of the terminal-side sub-band full duplex frequency domain resource configuration, the network-side sub-band full duplex frequency domain resource configuration, the uplink BWP corresponding frequency domain resource configuration, and the downlink BWP corresponding frequency domain resource configuration, and the second target frequency domain resource configuration is one of the terminal-side sub-band full duplex frequency domain resource configuration, the network-side sub-band full duplex frequency domain resource configuration, the uplink BWP corresponding frequency domain resource configuration, and the downlink BWP corresponding frequency domain resource configuration.

[0232] In some embodiments, if at least one of the uncompleted configured uplink transmission, the uncompleted configured downlink transmission, the uncompleted scheduled uplink transmission, and the uncompleted scheduled downlink transmission exists when the first timer and / or the second timer expires, the wireless communication method 200 further includes:

[0233] The terminal receives second information from the network side device, wherein the second information is used to indicate to suspend the first timer and / or the second timer, or the second information is used to indicate to reset the first timer and / or the second timer, or the second information is used to indicate to extend the opening duration of the first timer and / or the second timer; and / or,

[0234] The terminal sends third information to the network side device, wherein the third information is used to request to suspend the first timer and / or the second timer, or the third information is used to request to reset the first timer and / or the second timer, or the third information is used to request to extend the opening duration of the first timer and / or the second timer.

[0235] Optionally, the second information can be carried by DCI.

[0236] Optionally, the third information can be carried by Uplink Control Information (UCI).

[0237] For example, the network side device explicitly indicates to suspend the first timer and / or the second timer by a dedicated field in DCI, or the network side device explicitly indicates to reset the first timer and / or the second timer by a dedicated field in DCI, or the network side device explicitly indicates to extend the opening duration of the first timer and / or the second timer by a dedicated field in DCI.

[0238] For example, the network side device implicitly indicates to suspend the first timer and / or the second timer by scheduling or configuration information, or the network side device implicitly indicates to reset the first timer and / or the second timer by scheduling or configuration information, or the network side device implicitly indicates to extend the opening duration of the first timer and / or the second timer by scheduling or configuration information. For example, when there is a scheduled transmission, or a configured transmission, or a configured transmission resource, it means that the first timer and / or the second timer need to be suspended, or the first timer and / or the second timer need to be reset, or the opening duration of the first timer and / or the second timer needs to be extended.

[0239] Optionally, the suspension time of the first timer and / or the second timer can be agreed by protocol, or the suspension time of the first timer and / or the second timer can be configured by the network side (for example, by high layer configuration or physical layer indication of the suspension time of the first timer and / or the second timer).

[0240] Optionally, the length of the first timer and / or the second timer can be agreed by protocol, or the length of the first timer and / or the second timer can be configured by the network side (for example, the length of the first timer and / or the second timer is configured by high layer or indicated by physical layer).

[0241] In some embodiments, if the second information is used to indicate pausing the first timer and / or the second timer, the second information further comprises a pause time of the first timer and / or the second timer; and / or,

[0242] If the second information is used to indicate extending the on duration of the first timer and / or the second timer, the second information further comprises a length of the first timer and / or the second timer; and / or,

[0243] If the third information is used to request pausing the first timer and / or the second timer, the third information further comprises a pause time of the first timer and / or the second timer; and / or,

[0244] If the third information is used to request extending the on duration of the first timer and / or the second timer, the third information further comprises a length of the first timer and / or the second timer.

[0245] It should be noted that the length of the first timer and / or the second timer each time represents the length of the first timer and / or the second timer at the current time.

[0246] In some embodiments, if the second information is used to indicate pausing the first timer and / or the second timer, if there is no new indication from the network side device, it means that the first timer and / or the second timer is restarted after the expiration of the pause time, such as the first timer and / or the second timer continues to increase or decrease according to the size before pausing.

[0247] In some embodiments, if there is a configured continuous uplink transmission resource when the first timer expires, the terminal extends the first timer to the end position of the configured uplink transmission resource (in other words, the first timer expires at the end position of the configured uplink transmission resource); and / or,

[0248] If there is a configured continuous uplink transmission resource when the second timer expires, the terminal extends the second timer to the end position of the configured uplink transmission resource (in other words, the second timer expires at the end position of the configured uplink transmission resource).

[0249] For example, if there is a continuous uplink transmission resource configured when the first timer expires, the first timer is extended to the end of the configured uplink transmission resource by default.

[0250] For example, if there is a continuous uplink transmission resource configured when the second timer expires, the second timer is extended to the end of the configured uplink transmission resource by default.

[0253] In this embodiment, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the first time window, so that the terminal supporting terminal-side sub-band full-duplex can flexibly select the frequency domain resource configuration, can maximize the resource utilization, reduce the interference influence, and improve the system performance.

[0254] Optionally, the related information (such as the start time, the time length, the end time, the time domain offset relative to the reference point, the period, etc.) of the first time window is configured by the network side, or the related information (such as the start time, the time length, the end time, the time domain offset relative to the reference point, the period, etc.) of the first time window is related to the capability of the terminal, or the related information (such as the start time, the time length, the end time, the time domain offset relative to the reference point, the period, etc.) of the first time window is determined based on the capability of the terminal.

[0256] In some embodiments, the first time window is a non-periodic time domain resource, and the first time window takes effect after P2 time domain units after the terminal receives the trigger signaling from the network side device, wherein P2 is a positive integer.

[0257] Optionally, the trigger signaling can be used to activate or trigger the first time window, and / or the trigger signaling can be used to configure the related information (such as the start time, the time length, the end time, the period, etc.) of the first time window.

[0258] Optionally, the reference point is the time when the terminal receives the trigger signaling, or the reference point is configured by the network side, or the reference point is agreed by the protocol.

[0266] The terminal selects the first frequency domain resource configuration or the second frequency domain resource configuration according to the signal quality information measured by the terminal.

[0267] In this embodiment, if the terminal adopts a first target frequency domain resource configuration (such as a terminal-side sub-band full-duplex frequency domain resource configuration), the terminal can further switch the frequency domain resource configuration in the first target frequency domain resource configuration according to the location information of the terminal or the interference level measured by the terminal or the CSI, RSRP, RSRQ, or RSSI measured by the terminal.

[0272] Optionally, the value of Y can be agreed by a protocol, or the value of Y can be configured by the network side, or the value of Y is related to the capability of the terminal or the value of Y is determined based on the capability of the terminal.

[0279] In some embodiments, the terminal selects the first frequency domain resource configuration or the second frequency domain resource configuration according to the signal quality information measured by the terminal, including:

[0280] if the CSI, RSRP, or RSRQ measured by the terminal is greater than or equal to a fourth threshold value, or the RSSI measured by the terminal is less than or equal to a fifth threshold value, the terminal selects the first frequency domain resource configuration; and / or,

[0281] If the CSI, RSRP, or RSRQ measured by the terminal is greater than or equal to a sixth threshold value, or the RSSI measured by the terminal is less than or equal to a seventh threshold value, the terminal selects the second frequency domain resource configuration;

[0282] The fourth threshold value is greater than the sixth threshold value, and the fifth threshold value is less than the seventh threshold value.

[0288] Therefore, in the embodiment of the present application, the terminal selects the first target frequency domain resource configuration or the second target frequency domain resource configuration according to the first information; wherein the first information includes at least one of the following: whether the first object and the second object exist simultaneously in the first time domain unit; the first timer and / or the second timer; the first time window; the first indication information for indicating the transmission direction on the second time domain unit; the position information of the terminal; the signal quality information measured by the terminal; and the second indication information for indicating the rank or the number of layers. Thus, the terminal supporting terminal-side sub-band full duplex can flexibly select the frequency domain resource configuration, the resource utilization rate can be maximized, the interference influence can be reduced, and the system performance can be improved.

[0289] The technical scheme of the present application is described below by way of Embodiments 1 to 5.

[0290] Example 1, taking time domain unit T1 as the first time domain unit, for a terminal supporting full-duplex sub-band on the terminal side, when there is simultaneous uplink and downlink transmission within time domain unit T1, the frequency domain resource configuration of full-duplex sub-band on the terminal side is most effective. If there is only unidirectional transmission within time domain unit T1, such as uplink or downlink transmission, it can fall back to half-duplex mode, selecting the uplink or downlink sub-band corresponding to full-duplex sub-band on the network side, or selecting the uplink BWP for transmission, or selecting the downlink BWP for transmission, to avoid wasting guard band resources. Optionally, the technical solution of Example 1 can be implemented by at least one of the following schemes 1 to 5.

[0291] Option 1: If there are both scheduled or configured uplink transmissions and scheduled or configured downlink transmissions in time domain unit T1, the terminal selects the frequency domain resource configuration of full-duplex subband on the terminal side.

[0292] Option 2: If both scheduled or configured uplink transmission and configured downlink transmission resources exist simultaneously within time domain unit T1, the terminal selects the frequency domain resource configuration of full-duplex subband on the terminal side; wherein, the configured downlink transmission includes, but is not limited to, at least one of the following: Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS-PDSCH), Synchronization Signal Block (SSB), Periodic Channel State Information Reference Signal (CSI-RS), and Control Resource Set (CORESET).

[0293] Option 3: If both scheduled or configured downlink transmission and configured uplink transmission resources exist simultaneously within time domain unit T1, the terminal selects the frequency domain resource configuration of the full-duplex subband on the terminal side; wherein, the configured uplink transmission includes, but is not limited to, at least one of the following: a configured Physical Uplink Shared Channel (PUSCH), a Sounding Reference Signal (SRS), a Physical Random Access Channel (PRACH), or a periodic or semi-persistent Physical Uplink Control Channel (PUCCH).

[0294] Option 4: If both configured uplink and downlink transmission resources exist simultaneously within time domain unit T1, the terminal selects the frequency domain resource configuration of the full-duplex subband on the terminal side; wherein, the configured uplink transmission includes, but is not limited to, at least one of the following: configured PUSCH, SRS, PRACH, periodic or semi-continuous PUCCH; the configured downlink transmission includes, but is not limited to, at least one of the following: SPS-PDSCH, SSB, periodic CSI-RS, CORESET.

[0295] Option 5: In addition to the situations in Options 1-4, if only scheduled or configured uplink transmission exists in time domain unit T1, or only scheduled or configured downlink transmission exists in time domain unit T1, or only configured uplink transmission resources exist in time domain unit T1, or only configured downlink transmission resources exist in time domain unit T1, the terminal selects the frequency domain resource configuration of the network side subband full-duplex, or the terminal selects the frequency domain resource configuration corresponding to the uplink BWP, or the terminal selects the frequency domain resource configuration corresponding to the downlink BWP.

[0296] Optionally, time-domain unit T1 can be one or more symbols, or time-domain unit T1 can be one or more slots, or time-domain unit T1 can be one or more subframes, or time-domain unit T1 can be several milliseconds (ms), such as 0.5ms, 0.625ms, 1ms, 5ms, etc.

[0297] Example 2, taking time domain unit T2 as the second time domain unit, for a terminal supporting full-duplex sub-band on the terminal side, if the network-side device indicates the transmission direction on time domain unit T2 through first indication information (additional signaling), the terminal selects frequency domain resource configuration according to the transmission direction on time domain unit T2 indicated by the first indication information. For example, if the network-side device indicates that the transmission direction on time domain unit T2 is uplink (UL) or downlink (DL) through first indication information (such as TDD UL-DL configuration), the terminal considers time domain unit T2 to be in half-duplex transmission mode, and the terminal can select half-duplex transmission resources; optionally, the terminal selects the frequency domain resource configuration for full-duplex sub-band on the network side, or the terminal selects the frequency domain resource configuration corresponding to the uplink BWP, or the terminal selects the frequency domain resource configuration corresponding to the downlink BWP. If the first indication information (such as TDD UL-DL configuration) indicates that the transmission direction on time domain unit T2 is flexible, the terminal considers time domain unit T2 to be in sub-band full-duplex mode. At this time, the terminal needs to perform uplink and downlink transmissions simultaneously, and the terminal can select the frequency domain resource configuration of sub-band full-duplex on the terminal side.

[0298] Optionally, the network-side device can also indicate the transmission direction on time domain unit T2 through terminal-specific signaling or slot format indication (SFI) and other signaling.

[0299] In Example 3, the terminal can select appropriate frequency domain resource configurations based on its location, channel quality (such as Channel State Information (CSI) and Reference Signal Received Quality (RSRQ)), or interference level (such as Received Signal Strength Indication (RSSI)) to maximize resource utilization and improve system performance. For example, when the terminal is close to the base station, has good channel quality, or experiences little interference, the terminal can select full-duplex frequency domain resource configurations on its own sub-band, performing uplink and downlink transmissions simultaneously on the corresponding sub-band. Conversely, if the terminal is far from the base station, has poor channel quality, or experiences significant interference, the terminal can select full-duplex frequency domain resource configurations on the network side, performing only uplink or downlink transmissions on the corresponding sub-band to ensure transmission quality. The terminal's location, channel quality, and interference level can be obtained by comparing them with preset thresholds.

[0300] Example 4: Considering that when the terminal performs sub-band full-duplex transmission, the terminal's antenna configuration may be divided into two parts: one part for transmitting and the other for receiving. Compared to half-duplex transmission, which uses all antennas for either receiving or transmitting, the number of layers the terminal can transmit simultaneously is reduced. Therefore, the terminal can select frequency domain resource configuration based on the rank or number of layers indicated by the network-side device. For example, the network-side device indicates the rank or number of layers through a second indication. If the number of layers indicated by the network-side device exceeds the maximum number (or a specific threshold) that the antenna can support in sub-band full-duplex mode, the terminal switches to half-duplex mode for transmission. Similarly, if the number of layers indicated by the network-side device is less than or equal to the maximum number (or a specific threshold) that the antenna can support in sub-band full-duplex mode, the terminal can use sub-band full-duplex mode for transmission.

[0301] Example 5: When a terminal is configured with at least two terminal-side subband full-duplex frequency domain resource configurations, these configurations correspond to downlink subbands (DL subband), uplink subbands (UL subband), or guard bands of different bandwidths. The terminal can further select the corresponding terminal-side subband full-duplex frequency domain resource configuration based on its location, channel quality (CSI, RSRQ), or interference level (RSSI). For example, when the terminal is close to the base station, has good channel quality, or experiences low interference, the terminal can choose a terminal-side subband full-duplex frequency domain resource configuration with a smaller guard band. Conversely, if the terminal is far from the base station, has poor channel quality, or experiences high interference, the terminal can choose a terminal-side subband full-duplex frequency domain resource configuration with a larger guard band to ensure transmission quality. The terminal can select the corresponding terminal-side subband full-duplex frequency domain resource configuration by comparing the terminal location, channel quality, interference level, and a preset threshold. Guard bands can be configured explicitly or obtained implicitly. For example, a larger guard band is configured for a smaller bandwidth frequency domain resource in the downlink subband and / or uplink subband, and a smaller guard band is configured for a larger bandwidth frequency domain resource in the downlink subband and / or uplink subband.
