Abstract
The disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A communication method performed by a user equipment (UE) during a network communication procedure is provided. The communication method includes transmitting a random access preamble, receiving a modified random access response (RAR) comprising a sounding reference signal (SRS) request field whose value indicates whether the UE should transmit the SRS, when the SRS request field value indicates that the UE should transmit the SRS, transmitting the SRS, and receiving one or multiple subsequent downlink (DL) transmissions with adaptive spatial signal processing performed on the basis of a channel state information (CSI) acquired on the basis of measurements of the SRS.
