[0208] In related technologies, network-side full-duplex technology has been extensively researched, while full-duplex technology on the terminal 101 side needs to be enhanced. For example, because antenna isolation and self-interference cancellation are simpler and more feasible on the network device 102 side, related technologies limit the application of sub-band full-duplex (SBFD) within full-duplex technology to network devices 102. In some scenarios, there is a need to introduce full-duplex technologies such as SBFD on the terminal 101 side.

[0209] Network device 102 can perform power control based on terminal capabilities. Terminal 101 needs to report its maximum configured power to the base station. Terminal 101's transmit power in full-duplex mode may differ from the maximum configured power supported by terminal 101. If network device 102 still performs power control based on the maximum configured power reported by terminal 101, accuracy will be lost. Therefore, a method for network-side power control of terminal 101 in full-duplex mode is required.

[0210] Figure 2a is an interactive diagram of a method for sending and receiving indication information according to an embodiment of the present disclosure. As shown in Figure 2a, an embodiment of the present disclosure relates to a method for sending and receiving indication information, the method comprising:

[0211] Step S2101 , the terminal 101 sends instruction information to the network device 102 .

[0212] Optionally, the indication information is used to indicate power information supported by the terminal 101 in full-duplex mode.

[0213] In some embodiments, terminal 101 is a terminal 101 with strong anti-self-interference capability. In full-duplex mode, terminal 101 can meet at least one of the following conditions: low uplink transmission power, and a large guard interval between uplink symbols and downlink symbols in a full-duplex time domain unit.

[0214] Optionally, as shown in FIG2c , taking SBFD as an example, an uplink (UL) symbol is inserted into the subband corresponding to a downlink (DL) symbol within a carrier bandwidth, thereby achieving full-duplex transmission on that symbol. In other words, the carrier bandwidth can be divided into multiple subbands (SBs) within the frequency domain, including uplink and downlink subbands. When terminal 101 supports SDFD, it can transmit signals on the uplink subband while receiving signals on the downlink subband.

[0215] Optionally, a guard interval (gap) is provided between the uplink subband and the downlink subband to achieve uplink and downlink isolation. Alternatively, the subband includes multiple RBs, and the guard interval is provided between the uplink RB and the downlink RB.

[0216] Optionally, the transmit power of the terminal 101 in full-duplex mode is lower than the maximum configured power or power level supported by the terminal 101 .

[0217] In some embodiments, the indication is sent via one of the following:

[0218] MAC CE;

[0219] RRC information.

[0220] Optionally, when the terminal 101 sends indication information through MAC CE or RRC information, it can use new signaling to send it, or reuse existing signaling to send it.

[0221] For example, taking the example of the terminal 101 sending the indication information through the MAC CE, the terminal 101 may introduce a new MAC CE to send the indication information, or may reuse the MAC CE used to send the power headroom report (Power Headroom Report, PHR) to send the indication information.

[0222] In some embodiments, the power information is at least one of the following:

[0223] Maximum power back-off (MPR) for full-duplex mode SBFD ;

[0224] Maximum allowed transmit power for full-duplex mode SBFD .

[0225] Optionally, the terminal 101 may calculate and report the maximum configured power P according to the relevant protocol. CMAX . In reporting P CMAX In addition, you need to report MPR SBFD or power SBFD , so that the network device 102 can perform power control in the full-duplex mode of the terminal 101 according to the information reported by the terminal 101.

[0226] Optionally, MPR SBFD P reported by terminal 101 in full-duplex mode CMAX Or the back-off value (dB) corresponding to the power level.

[0227] Optionally, power SBFD is the maximum allowed transmit power value (dBm) supported by terminal 101 in full-duplex mode.

[0228] Optionally, MPR SBFD or power SBFD Carried in the PHR MAC CE entity.

[0229] In the first example, the MAC CE includes a first information field; wherein the first information field is used to indicate power information; or, the first information field is a reserved (R) field, and the reserved field is used to indicate power information when the terminal needs to report power information.

[0230] As shown in Figure 2d, the first information field may be the MPR added in the PHR MAC CE. SBFD or power SBFD Domain (shown in MPR SBFD Alternatively, the first information field may be the R field of the multiplexed PHR MAC CE. CMAX,f,c That is, P CMAX Among them, the first information field is used to indicate MPR SBFD or power SBFD Or, when there is no MPR SBFD or power SBFD When reporting, only the R bit may be reserved in the first information field.

[0231] As shown in Figure 2e, a new type of MAC CE is introduced, and the MPR is indicated through the first information field of the MAC CE SBFD or power SBFD (The figure shows MPR SBFD The example in the figure is applicable to the case where the terminal 101 operates in frequency range 2 (FR2).

[0232] In the second example, the MAC CE includes a second information field, where the second information field is used to indicate power information when a condition is met.

[0233] In this example, the second information field may be the MPR added in the PHR MAC CE. SBFD or power SBFD Alternatively, the second information field may be the R field of the multiplexed PHR MAC CE.

[0234] In this example, when the terminal 101 operates in FR2, the power information can also be indicated in combination with the reporting of the MPE.

[0235] In this example, the condition is satisfied when the value corresponding to the information field satisfies the set value. For example, when the second information field is 1, the MPR needs to be reported. SBFD or power SBFD .

[0236] In one embodiment of this example, the MAC CE also includes a third information field, which is used to indicate power backoff information; when the third information field is a first value, the second information field is used to indicate the maximum value between the power information and the MPE; or, when the third information field is a second value, the second information field is used to indicate the power information.

[0237] Optionally, the third information field is the P field in the following embodiment. Taking the third information field occupying 1 bit as an example, the first value may be 1 and the second value may be 0. For example, when the P field value is 1, the second information field is used to indicate power information such as MPR. SBFD and the maximum value among MPE; when the P field value is 0, the second information field is used to indicate power information such as MPR SBFD .

[0238] In another embodiment of this example, the MAC CE also includes a third information field and a fourth information field, and the third information field is used to indicate power backoff information; when the third information field and the fourth information field are both first values, the second information field is used to indicate the maximum value between the power information and the MPE; when the third information field is the second value and the fourth information field is the first value, the second information field is used to indicate the power information.

[0239] As shown in Figure 2f, the third information field is the P field. If the parameter mpe-Reporting-FR2 is configured and the serving cell operates in FR2, when the fallback P-MPR value applied by the terminal 101 meets the MPE requirements defined in the protocol and is less than the P-MPR_00 specified in the protocol, the MAC entity shall set the P field to 0, otherwise it shall be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in FR1, the P field indicates whether power fallback such as P-MPR is applied due to power management. c If power backoff due to power management is not applied, the corresponding P CMAX,f,c The P field will have a different value, the MAC entity sets the P field to 1.

[0240] As shown in FIG. 2f and in combination with FIG. 2d , the fourth information field may reuse an R field in the PHR MAC CE.

[0241] In this example, taking the third information field (P field) and the fourth information field (R field) as an example, the fourth information field can indicate whether the MAC CE reports MPE or power information such as MPR through 1 bit information. SBFD .

[0242] For example, the first value may be 1 and the second value may be 0. When the P field value is 1 and the R field value is also 1, the second information field is used to indicate power information such as MPR. SBFD and the maximum value among MPE; when the P field value is 0 and the R field value is 1, the second information field is used to indicate power information such as MPR SBFD When the P field value is 1 and the R field value is 0, the second information field is used to indicate MPE. This method can more accurately determine the indicated power information such as MPR SBFD Still MPE.

[0243] In some embodiments, MPR SBFD or power SBFD Has a mapping relationship with at least one of the following:

[0244] subcarrier;

[0245] The guard interval between the uplink resource block RB and the downlink resource block;

[0246] The location of the resource being configured;

[0247] The bandwidth of the allocated resources;

[0248] Modulation method;

[0249] waveform.

[0250] Optionally, MPR SBFD or power SBFD It can be the MPR that the terminal 101 predetermines based on the resource configuration of the network device 102, and the corresponding MPR under different resource configuration conditions SBFD or power SBFD Different. For example, different subcarriers have corresponding MPRs SBFD or power SBFD .

[0251] Optionally, the guard interval (gap) satisfies one of the following:

[0252] Includes at least one RB, for example, a gap is granular with RBs, such as 2 RBs;

[0253] Includes one or more subcarriers, for example, a gap is based on a subcarrier granularity, such as 30 subcarriers;

[0254] In frequency units, for example, gap is XMHz, where X is a number greater than 0;

[0255] Greater than a threshold, for example, the gap is greater than a preset threshold;

[0256] Less than a threshold, for example, the gap is less than a preset threshold.

[0257] In one example, the gap size is in RB granularity and the power information is in MPR. SBFD For example, the mapping relationship between power information and gap can be seen in Table 1:

Optionally, the terminal reports the maximum allowed power information in full-duplex mode (including FD / SBFD) to the base station, and preferably the maximum allowed power information is carried in the PHR MAC CE entity. To facilitate understanding of the embodiments of the present disclosure, some embodiments are listed below:

[0371] Example 1

[0372] When a terminal is configured in SBFD or full-duplex mode, the terminal needs to consider the impact of full-duplex on the maximum power when determining the maximum configured power.

[0373] In one embodiment, the impact of full duplex is similar to the maximum power backoff (MPR). SBFD .

[0374] When determining the maximum configuration power Pcmax, possible solutions are as follows:

[0375] Example 1:

[0376] The calculation of Pcmax_L and Pcmax_H needs to take MPR into account SBFD , the possible calculation methods are as follows:

[0377] 1)P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;in,

[0378] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c ), P PowerClass -MPR SBFD};

[0379] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔP PowerBoost , P PowerClass -MPR SBFD}.

[0380] 2)P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;in,

[0381] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c , MPR SBFD )};

[0382] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔP PowerBoost -MPR SBFD )}.

[0385] 1)P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;in,

[0386] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c ), P PowerClass -MPR SBFD};

[0387] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔP PowerBoost}.

[0388] 2)P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;in,

[0389] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c , MPR SBFD )};

[0391] Optionally, MPR SBFDIt is a fallback value relative to the terminal power level. It is determined by the terminal based on the base station's configured resources, such as the subcarrier size, the gap (guard interval) between uplink and downlink resource blocks, or similarly determined by the location, size and / or bandwidth, waveform, and modulation method of the uplink and downlink resources. The size of the gap can be one of the following:

[0392] The granularity is RB, such as 2RB;

[0393] The granularity is subcarrier, such as 30 subcarriers;

[0394] In units of frequency, such as MHz;

[0395] The size is determined by high and low information. For example, high means that the gap is greater than a preset value, and low means that it is less than a preset value.

[0396] Optionally, an embodiment in which the gap size is based on RB granularity can be seen in Table 1.

[0397] In another embodiment, the effect of full duplex can be similar to the maximum allowed power, such as: SBFD This refers to the actual allowed power value, such as dBm, rather than the fallback value in dB relative to the power level.

[0403] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔP PowerBoost , power SBFD}.

[0404] Example 4:

[0405] Only the calculations in Pcmax_L consider power SBFD , the possible calculation methods are as follows:

[0406] 1)P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;in,

[0407] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c , P PowerClass ), power SBFD};

[0408] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass +ΔP PowerBoost}.

[0409] Optionally, power SBFD The terminal also determines the uplink and downlink resource allocation according to the base station's configured resources, such as the subcarrier size, the gap between uplink and downlink resource blocks, or the uplink and downlink resource location, size and / or bandwidth, waveform, and modulation method.

[0411] Example 2

[0412] The calculation of Pcmax is not affected, MPRSBFD Report separately, in one embodiment MPR SBFD Carried in the PHR MAC CE entity, such as adding an MPR in the PHR MAC CE entity SBFD The information field indicates MPR SBFD The size or reserved bits. When there is no MPR SBFD When reporting, the information field only contains reserved bits. A possible solution is shown in Figure 2d.

[0413] Optionally, the above solution can be used in conjunction with the existing MPE entity in the FR2 frequency band, and 1 bit of information can be used to indicate whether the report is MPE or MPR. SBFD , such as can be indicated by the R bit of MAC CE, when MPE and MPR SBFD When both values ​​need to be reported, the larger value of the two can be reported, as shown in Figure 2f.

[0414] Alternatively, in another solution, a new type of MAC CE is introduced, as shown in FIG2e , to report the MPR. SBFD .

[0415] Optionally, the above MPR SBFD It can be determined according to the method in embodiment 1, that is, the terminal determines it according to the resource information configured by the base station for the terminal.

[0416] Alternatively, in another embodiment, MPR SBFD It can be Power SBFD , can be the actual allowed power value, such as dBm, rather than the back-off value dB value relative to the power level.
