1. A method comprising:
receiving, by a terminal, from a base station, first configuration information related to a sounding reference signal (SRS), wherein the first configuration information includes information on a plurality of SRS resource sets;
receiving, by the terminal, from the base station, downlink control information (DCI) for scheduling a PUSCH (physical uplink shared channel); and
transmitting, by the terminal, to the base station, the PUSCH based on the DCI,
wherein the DCI includes a plurality of SRS resource indicator (SRI) fields and each of the plurality of SRI fields is related to each of the plurality of SRS resource sets, respectively,
wherein the PUSCH is repeatedly transmitted at N (N is an integer greater than 1) transmission occasions (TOs),
wherein the N TOs are grouped into TO groups of a plurality of continuous TOs,
wherein the plurality of the SRS resource sets are respectively mapped to each of the TO groups based on a mapping relation, and
wherein one SRI field among the plurality of SRI fields is applied to the PUSCH for each of the TO groups, based on one SRS resource set mapped to each of the TO groups.
