Abstract: A method of operating a wireless communication device includes calculating a first channel matrix for a downlink channel based on a CSI-RS, determining a stage level of a multi-stage vector quantization process based on an uplink channel, extracting, using a first machine learning model, a latent vector based on the first channel matrix, selecting a first codeword from a first codebook corresponding to a first stage, and generating, in the first stage, a first residual latent vector based on the latent vector, selecting, in a second stage corresponding to the determined stage level, a second codeword from a second codebook corresponding to the second stage, and generating, in the second stage, a second residual latent vector based on the first residual latent vector, wherein the second residual latent vector is based on a second codeword, and generating a bitstream based on the first codeword and the second codeword.

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.
