Method and device for physical uplink shared channel transmission power determination in wireless communications

A user equipment (UE), comprising:

• a receiver configured to receive downlink control information (DCI) that schedules a physical uplink shared channel (PUSCH);
• and
• a transmitter configured to transmit a first signal and a second signal on the PUSCH,
• wherein the DCI includes a first sounding reference signal (SRS) resource indicator that indicates a first SRS resource of a first SRS resource set and a second SRS resource indicator that indicates a second SRS resource of a second SRS resource set, and a first power value is associated with the first SRS resource indicator, and a second power value is associated with the second SRS resource indicator, and
• wherein:
• an antenna port of the first signal is the same as an antenna port of the first SRS resource, and a linear value of a transmission power of the first signal on the PUSCH is based on a product of a linear value of the first power value and a first coefficient, and
• an antenna port of the second signal is the same as an antenna port of the second SRS resource, and a linear value of a transmission power of the second signal on the PUSCH is based on a product of a linear value of the second power value and a second coefficient.
