Methods and apparatuses for multiple transmit-receive point (M-TRP) based physical uplink shared channel (PUSCH) transmission

A base station (BS) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the BS to:
• transmit configuration information of a first sounding reference signal (SRS) resource set and a second SRS resource set for a codebook or non-codebook based physical uplink shared channel (PUSCH) transmission;
• transmit a configured grant (CG) configuration for the PUSCH transmission, wherein the CG configuration comprises one or two sets of power control parameters, and each set of power control parameter is associated with one SRS resource set of the first SRS resource set or the second SRS resource set;
• and
• transmit downlink control information (DCI) scheduling a PUSCH retransmission corresponding to the PUSCH transmission according to the CG configuration.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive configuration information of a first sounding reference signal (SRS) resource set and a second SRS resource set for a codebook or non-codebook based physical uplink shared channel (PUSCH) transmission;
• receive a configured grant (CG) configuration for the PUSCH transmission, wherein the CG configuration comprises one or two sets of power control parameters, and each set of power control parameter is associated with one SRS resource set of the first SRS resource set or the second SRS resource set;
• receive downlink control information (DCI) scheduling a PUSCH retransmission corresponding to the PUSCH transmission according to the CG configuration;
• and
• determine at least one set of power control parameters for the PUSCH retransmission.
