Claim 5:
6. A user equipment for transmitting an uplink channel in a wireless communication system, the user equipment comprising:
at least one memory storing a program to transmit the uplink channel; and
at least one processor, by performing the program, configured to:
receive, from a base station through radio resource control (RRC) signaling, information indicating one of implicit precoding or explicit precoding and information configuring a plurality of sounding reference signal (SRS) resources, wherein the plurality of SRS resources are related with one channel state information-reference signal (CSI-RS) resource,
acquire an SRS resource indicator (SRI) in downlink control information (DCI) received through a physical control channel, wherein the SRI indicates at least one SRS resource from among the plurality of SRS resources,
based on the implicit precoding being indicated, obtain 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 transmit, to the base station, the uplink channel based on the precoding information.
