Example Embodiment
[0691] Example 1:
[0692] The base station configures multiple SRS resources for the terminal to be used for codebook-based PUSCH transmission CSI measurement (for example, in the NR system Rel-15, usage is configured as an SRS resource in the SRS resource set of 'codebook'), one or more of which The number of antenna ports included in each SRS resource is equal to the maximum number of antenna ports that can be included in one SRS resource supported by the terminal, and the number of antenna ports included in the remaining SRS resources (which may be one or more) is less than the number of antenna ports included in one SRS resource supported by the terminal. Maximum number of antenna ports. Optionally, the SRS resource that includes the number of antenna ports equal to the maximum number of antenna ports that can be included in one SRS resource supported by the terminal is one, and the number of antenna ports included is less than the SRS resource that can include the maximu...

[0719] Example 2:
[0720] The base station configures multiple SRS resources for the terminal for CSI measurement based on codebook PUSCH transmission (for example, in the NR system Rel-15, SRS resources in the SRS resource set whose usage is configured as 'codebook'), all SRS resources The number of included antenna ports (which may be one or more) is less than the maximum number of antenna ports that can be included in one SRS resource supported by the terminal.
[0721] For an SRS resource whose number of antenna ports is less than the maximum number of antenna ports that can be included in one SRS resource supported by the terminal, the terminal may use antenna virtualization to use multiple Tx chains and / or PAs to transmit the same SRS antenna port. Of course, the terminal can also send an SRS port through a Tx chain or PA.
[0722] When codebook-based PUSCH transmission is scheduled through DCI format 0_1, the terminal uses the following PUSCH transmit power adjustmen...

[0748] Example 3:
[0749] The base station configures multiple SRS resources for the terminal for codebook-based PUSCH transmission CSI measurement (for example, in the NR system Rel-15, SRS resources in the SRS resource set whose usage is configured as 'codebook').
[0750] For SRS resources that contain antenna ports less than the maximum number of antenna ports that can be contained in one SRS resource supported by the terminal, the terminal can use antenna virtualization to transmit the same SRS using multiple Tx chains and / or PAs Antenna port.
[0751] When codebook-based PUSCH transmission is scheduled through DCI format 0_1, the terminal uses the following PUSCH transmit power adjustment rules:
[0752] For m SRS resources, when the SRS resource indicated by the SRI is any of the m resources, the terminal uses N / M transmission power of the PUSCH 1 Scaling, and then evenly distributed to the antenna ports of each PUSCH non-zero transmission;
[0753]When the SRS reso...
