Abstract: Disclosed are a method and a device for transmitting or receiving a PUSCH in a wireless communication system. A method for transmitting a physical uplink shared channel (PUSCH) according to an embodiment of the present disclosure may comprise the steps of: receiving first configuration information related to a sounding reference signal (SRS) from a base station; receiving downlink control information (DCI) for PUSCH scheduling from the base station; and transmitting the PUSCH to the base station. On the basis that the first configuration information includes information relating to multiple SRS resource sets, the PUSCH is transmitted at N (N is a natural number) transmission occasions (TOs), and the DCI includes multiple SRS resource indicator (SRI) fields, the PUSCH may be transmitted at each of the TOs on the basis of an SRS resource in an SRS resource set identified by one SRI field among the multiple SRI fields related to each of the TOs.

Abstract: Methods and apparatuses for performing communication in a wireless communication system. A user equipment (UE) receives first satellite ephemeris information related to a first satellite and information related to a first validity duration corresponding to the first satellite from a base station; and restarts a first validity timer, based on second satellite ephemeris information related to the first satellite being received from the base station while the first validity timer having the first validity duration is running. The UE obtains a first TA for the first satellite based on the first satellite ephemeris information before the first validity timer restarts, expires, or stops after starting based on the first validity duration, and the UE obtains a second TA for the first satellite based on the second satellite ephemeris information before the first validity timer expires or stops after restarting based on a second validity duration.
