Disclosed are a method and apparatus for transmitting/receiving a physical uplink shared channel (PUSCH) in a wireless communication system. According to one embodiment of the present disclosure, a method for transmitting a PUSCH may comprise: a step of receiving downlink control information (DCI) for PUSCH scheduling form a base station; and a step of transmitting the PUSCH to the base station. The PUSCH is transmitted at N (N is a natural number) transmission occasions (TOs), wherein at each TO, one or more power control parameters of the PUSCH may be determined on the basis of an SRS resource indicator (SRI) field value in the DCI.
