1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message including physical uplink shared channel (PUSCH) power control configurations, a first P0-PUSCH set list, and a second P0-PUSCH set list;
receiving, from the base station, downlink control information (DCI) including a transmission power control (TPC) command value and an open-loop power control parameter set indicator;
in case that the DCI includes two sounding reference signal (SRS) resource indicators (SRIs) and the open-loop power control parameter set indicator is configured to 1;
determining a first transmission power associated with a first transmission reception point (TRP) based on a first PUSCH power control configuration corresponding to a first SRI, the TPC command value, and a first value of a P0-PUSCH set corresponding to the first SRI, the P0-PUSCH set corresponding to the first SRI being included in the first P0-PUSCH set list, and
determining a second transmission power associated with a second TRP based on a second PUSCH power control configuration corresponding to a second SRI, the TPC command value, and a first value of a P0-PUSCH set corresponding to the second SRI, the P0-PUSCH set corresponding to the second SRI being included in the second P0-PUSCH set list;
transmitting, to the first TRP, a PUSCH based on the first transmission power; and
transmitting, to the second TRP, the PUSCH based on the second transmission power.
