Claim 4:
5. A method, performed by a base station, of receiving an uplink channel in a wireless communication system, the method comprising:
transmitting, to a user equipment 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; and
receiving, from the user equipment, the uplink channel based on precoding information for the uplink channel,
wherein, based on the implicit precoding being indicated, the precoding information for the uplink channel is obtained based on the CSI-RS resource related with a most recently transmitted SRS of at least one SRS resource indicated from among the plurality of SRS resources by an SRS resource indicator (SRI) in downlink control information (DCI) transmitted through a physical control channel.
