[0110] In the embodiment of the present disclosure, during the SRS antenna switching process of terminal 101, terminal 101 uses different antennas, such as receiving antennas, to transmit SRS. The maximum transmit power of terminal 101 transmitting SRS on the receiving antenna is related to the power class (PC) of the transmit power supported by terminal 101 in the current frequency band.

[0111] In the embodiment of the present disclosure, the terminal 101 can be configured to support the PC and the additional insertion loss (ΔT RxSRS ), determine the maximum configured output power (configured maximum output power, P) according to the defined power calculation method CMAX For example, the terminal 101 may determine the maximum configured output power P of any time slot of the carrier f of the serving cell c within the following range: CMAX,f,c :

[0112] P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c , where P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}; P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass};

[0113] Among them, P EMAX,c The maximum transmit power configured for the network device 102, P PowerClass is the power level of terminal 101, MPR c That is MPR, A-MPR c That is A-MPR, ΔT IB,c is the additional power offset, P-MPR c The maximum power fallback value when meeting the electromagnetic radiation standard absorbed by the human body terminal, ΔT C,c and ΔT RxSRS It is understood that the meanings of the above parameters can also refer to the definitions of relevant protocols.

[0114] ΔP PowerClass is the power level difference. When the following conditions are met, ΔP PowerClass3dB: The SRS resource set (SRS resources set) at the SRS transmission opportunity is set to 'antennaSwitching' and the configured SRS resources in each SRS resource set include an SRS port, the terminal 101 further indicates that the SRS-TxSwitch capability is 't1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r4', the terminal 101 supports transmit diversity capabilities such as txDiversity-r16 and supports PC2, or the terminal 101 supports PC1.5. In other scenarios, ΔP PowerClass is 0dB.

[0115] In the embodiment of the present disclosure, when the terminal 101 supports a certain power level by supporting the transmit diversity capability (txDiversity capability), the terminal 101 can transmit through N links (N≥2) to achieve a total transmit power that meets the target power level. However, in the SRS antenna switching scenario, the terminal 101 cannot support transmit diversity, and its actual transmit power depends on a single transmit link. CMAX In the process, the power level (P PowerClass ) will be reduced by 10log(n), such as the power level difference ΔP based on the power level PowerClass The value is 3dB.

[0116] For high-capability terminals 101, when using a single link, it is also possible to use a larger value than (P PowerClass -ΔP PowerClass ) power level, or reach P PowerClass However, based on the above method, the terminal is forced to reduce the power by ΔPPowerClass after the SRS switching, which makes it impossible to exert the maximum power capability of the terminal, thereby affecting the performance of the SRS antenna switching.

[0117] In an embodiment of the present disclosure, a method for a high-capability terminal to report its capabilities during SRS antenna switching is provided.

[0126] Optionally, the terminal 101 may synchronously report support for the second capability in the capability information, such as using a preset bit to indicate whether the second capability is supported, for example, using 1 bit to indicate whether the second capability is supported.

[0127] Optionally, the transmit diversity capability may be txDiversity-r16 capability.

[0128] Optionally, the set power level may be PC1.5.

[0129] In one example, when the terminal 101 supports transmit diversity capability or PC1.5, the terminal 101 transmits capability information to the network device 102 to indicate whether ΔP is supported when sending SRS. PowerClass is 0dB.

[0130] In some embodiments, the capability information includes a second field for indicating the first capability.

[0131] Optionally, the second field may occupy a second information field, and indicate whether the terminal 101 supports the first capability through a bit value of the second information field.

[0132] Optionally, the second information field may occupy one or more bits.

[0133] Optionally, taking the second information field occupying 1 bit as an example, when the value of the 1 bit is 1, it indicates that the terminal 101 supports the first capability; when the value of the 1 bit is 0, it indicates that the terminal 101 does not support the first capability.

[0134] In some embodiments, network device 102 receives the capability information.

[0136] In some embodiments, when the terminal 101 supports the first capability, P is determined based on the zero power level difference. CMAX .

[0137] In some embodiments, P CMAX Between its corresponding upper and lower limits, such as P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c .

[0138] In some embodiments, in step S2102, the terminal 101 may determine P according to the zero power level difference. CMAX upper and / or lower limits.

[0139] In one example, a zero power level difference is applicable to the calculation of the upper limit value, for example:

[0140] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}, where ΔP PowerClass =0dB; or expressed as, P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,P PowerClass –MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}.

[0141] In this example, when the following conditions are met: the SRS resource set of the SRS transmission opportunity is set to 'antennaSwitching' and the configured SRS resources in each SRS resource set include one SRS port, the terminal 101 further indicates that the SRS-TxSwitch capability is 't1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r4', the terminal 101 supports a transmit diversity capability such as txDiversity-r16 and supports PC2 or the terminal 101 supports PC1.5, and the terminal 101 indicates support for the first capability, P is calculated. CMAX The upper limit value of the process ΔP PowerClass is 0dB, calculate P CMAX The lower limit value of the process ΔP PowerClass 3dB. In other scenarios, ΔP PowerClass is 0dB.

[0142] In another example, zero power level difference is applicable to the calculation of upper and lower limits, for example:

[0143] P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}, where ΔP PowerClass =0dB;

[0144] P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass}, where ΔP PowerClass =0dB.

[0145] In this example, when the following conditions are met: the SRS resource set of the SRS transmission opportunity is set to 'antennaSwitching' and the configured SRS resources in each SRS resource set include one SRS port, the terminal 101 further indicates that the SRS-TxSwitch capability is 't1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r4', the terminal 101 supports transmit diversity capability such as txDiversity-r16 and supports PC2 or the terminal 101 supports PC1.5, and the terminal 101 does not indicate support for the first capability, ΔPPowerClass 3dB. In other scenarios, ΔP PowerClass is 0dB.

[0146] In some embodiments, the capability information includes a first field for indicating that the zero power level difference applies to the upper limit value and / or the lower limit value.

[0147] Optionally, the first field may occupy the first information field.

[0148] Optionally, the first information field may occupy one or more bits.

[0149] Optionally, taking the first information field occupying 1 bit as an example, when the value of the 1 bit is 0, it indicates that the zero power level difference applies to the upper limit value; when the value of the 1 bit is 1, it indicates that the zero power level difference applies to the upper limit value and the lower limit value.

[0150] Optionally, taking the first information field occupying 2 bits as an example, the 2 bits correspond to the upper limit value and the lower limit value respectively in a bitmap manner, and when the value of any bit is 1, it indicates that the zero power level difference applies to the upper limit value or the lower limit value corresponding to the bit. For example, when the value of the 2 bits is 10, it indicates that the zero power level difference applies to the upper limit value, when the value of the 2 bits is 01, it indicates that the zero power level difference applies to the lower limit value, and when the value of the 2 bits is 11, it indicates that the zero power level difference applies to both the upper limit value and the lower limit value.

[0151] In this embodiment, the first information field can be used to distinguish whether the first capability is applicable only to the calculation of the upper limit value or also to the calculation of the lower limit value.

[0285] To facilitate understanding of the embodiments of the present disclosure, some specific examples are listed below:

[0286] In the disclosed embodiment, the terminal indicates to the base station whether it has the capability of no-deltaPPowerClass. The base station determines whether the terminal has the capability of power class difference based on the capability reported by the terminal, thereby determining that the terminal can support the maximum power information when the SRS antenna is switched.

[0287] Example 1:

[0288] The terminal indicates to the base station whether it has the capability of no-deltaPPowerClass. The base station determines whether the terminal has the capability of power class difference based on the capability reported by the terminal, thereby determining the power class information of the terminal when the SRS antenna is switched.

[0289] Optionally, the terminal indicates to the base station whether it has the capability of no-deltaPPowerClass (No-deltaPPowerClass), and preset bit information may be used to indicate whether the terminal has the capability of no-deltaPPowerClass (No-deltaPPowerClass), for example, the preset bit is 1 bit.

[0290] Optionally, when the terminal indicates to the base station that it has the capability of no-deltaPPowerClass, when the terminal calculates the maximum configured power for transmitting the SRS sounding reference signal, ΔP PowerClass =0dB, otherwise the relevant protocol remains unchanged.

[0291] In one embodiment, the above ΔP PowerClass =0dB only applies to P CMAX_H,f,c， That is, the maximum configuration power P CMAX,f,c Calculation of upper limit.

[0294] ΔP in other scenarios PowerClass is 0dB.

[0295] In another embodiment, the above ΔP PowerClass =0dB applies to both P CMAX_H,f,c， That is, the maximum configuration power P CMAX,f,c The calculation of the upper limit also applies to P CMAX_L,f,c That is, the lower limit of the maximum configuration power is calculated.

[0296] Corresponding:

[0297] When the following conditions are met: the SRS resource set of the SRS transmission opportunity is set to 'antennaSwitching' and the configured SRS resources in each SRS resource set include one SRS port, the terminal 101 further indicates that the SRS-TxSwitch capability is 't1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r4', the terminal 101 supports transmit diversity capability such as txDiversity-r16 and supports PC2 or the terminal 101 supports PC1.5, and the terminal 101 does not indicate support for the first capability, ΔP PowerClass 3dB;

[0298] ΔP in other scenarios PowerClass is 0dB.

[0299] In one embodiment, the capability without power level difference can be reported only when the terminal reports whether it has transmit diversity capability (eg, txDiversity-r16 capability) or the terminal supports PC1.5 power level.

[0300] Optionally, the no-deltaPPowerClass capability corresponds to the first capability of the aforementioned embodiment.

[0301] Example 2:
