示例性的，UE接收高层信令，获得一套P0-PUSCH-SetList-r16配置，得到多个第四偏移值，SRI域的SRI值分别叠加不同的第四偏移值后，分别映射到一套P0-PUSCH-SetList-r16，获得多套P0-PUSCH-Set-r16。
示例3：
首先，UE接收高层信令，该高层信令配置两个用于码本传输的SRS resource set，存在两个sri-PUSCH-MappingToAddModList与上述两个SRS resource set关联，两个P0-PUSCH-SetList-r16与SRS resource set关联。此外，UE接收用于调度PUSCH传输的DCI，该DCI的SRI域指示了两个来自不同SRS resource set的SRS resource用于PUSCH传输。此时，DCI的SRI域的取值分别映射到两个sri-PUSCH-MappingToAddModList，以获得与两个SRS resource关联的两个SRI-PUSCH-PowerControl(分别包含P0_a,P0_b)。然后，再将DCI的SRI域的取值分别映射到映射到两个P0-PUSCH-SetList-r16上，获得与两个SRS resource关联的两个P0-PUSCH-Set-r16(分别包含P0_c,P0_d)。
接着，当高层信令配置OLPC域的大小是1bit，‘0’表示两套功率控制参数的两个P0分别等于两个SRI-PUSCH-PowerControl中的P0_a,P0_b。‘1’表示两套功率控制参数的两个P0取两个P0-PUSCH-SetList-r16中的P0_c,P0_d。
当高层信令配置OLPC域的大小是2比特，最高有效位关联第一SRS资源，最低有效位关联第二SRS资源，则OLPC域的取值的解释如下表3所示：

进一步可选地，在本申请实施例中，一个传输时机对应至少一套功率控制参数。

在一种示例中，当PUSCH的重复传输次数为1时，若该PUSCH的传输时机采用多套功率控制参数，则前一半OFDM符号采用一套功率控制参数，后一半OFDM符号采用另一套功率控制参数。
例如，当PUSCH的重复传输次数为1时，调度该PUSCH的DCI的SRI指示的码点关联了两个属于不同SRS resource set的SRS资源，则PUSCH的传输时机的前N/2个符号采用与码点中的第一个SRS资源相同的空间关系传输，余下N-N/2个符号采用与码点中的第二个SRS资源相同的空间关系传输。此时，SRI域映射到两个sri-PUSCH-MappingToAddModList上，得到两套功率控制参数组SRI-PUSCH-PowerControl。其中，上述PUSCH的传输时机的前N/2个符号采用的发射功率由第一SRS resource set关联的PUSCH-MappingToAddModList上映射的功控参数计算得到，余下N-N/2个的发射功率由第二SRS resource set关联的PUSCH-MappingToAddModList上映射的功率控制参数计算得到。
示例性的，当PUSCH的复传输次数大于1时，该PUSCH的一个传输时机采用一套功率控制参数。
