Abstract
A method of operating a wireless communication device including a plurality of antennas according to an exemplary embodiment of the present disclosure includes determining an antenna subset including at least one of the plurality of antennas, transmitting a sounding reference signal (SRS) switching signal to a base station through at least one antenna of the antenna subset, receiving a channel state information-reference signal (CSI-RS) transmitted using a first beam from the base station, selecting a precoding matrix indicator (PMI) based on the CSI-RS, transmitting the selected PMI to the base station, and receiving a signal transmitted from the base station through a second beam determined based on the SRS switching signal and the PMI.
