1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, configuration information including information on sets of power control parameters configured for transmission reception points (TRPs) for a physical uplink control channel (PUCCH) transmission;
receiving, from the base station, activation information for one or more of the sets of power control parameters; and
performing repetition of the PUCCH transmission for one or more of the TRPs, based on the configuration information and the activation information,
wherein the UE transmits, to the base station, UE capability information including information indicating that the UE supports a PUCCH power control associated with multiple TRPs, and
wherein the UE performs the PUCCH power control by alternating between the sets of power control parameters per repetition of the PUCCH transmission based on a cyclic mapping pattern being configured for repetitions of the PUCCH transmission.
