1. A method performed by a user equipment in a wireless communication system, the method comprising:
receiving, from a base station, information configuring a plurality of sounding reference signal (SRS) resources that are related with one channel state information-reference signal (CSI-RS) resource;
receiving an SRS resource indicator (SRI) indicating at least one SRS resource from among the plurality of SRS resources;
obtaining, based on an implicit precoding being indicated for an uplink channel, precoding information for the uplink channel based on the CSI-RS resource related with a most recently transmitted SRS of the at least one SRS resource indicated by the SRI; and
transmitting, to the base station, the uplink channel based on the precoding information.
