1. A method performed by a terminal in a communication system, the method comprising:
receiving, via higher layer signaling, a physical uplink shared channel (PUSCH) configuration including information on PUSCH repetition and a sounding reference signal (SRS) configuration including information on a first SRS resource set and information on a second SRS resource set, wherein the first SRS resource set and the second SRS resource set respectively include one or more at least one SRS resource;
receiving a downlink control information (DCI) format including an SRS resource set indicator field with 2 bits, a first SRS resource indicator field and a second SRS resource indicator field, wherein codepoints of the SRS resource set indicator field are mapped to associations of the first SRS resource set and the second SRS resource set to the PUSCH repetition; and
transmitting the PUSCH repetition by applying at least one of the first SRS resource indicator field or the second SRS resource indicator field according to at least one of the first SRS resource set or the second SRS resource set that is identified as associated with the PUSCH repetition based on the SRS resource set indicator field.
