PRECODER SELECTION METHOD AND APPARATUS FOR PERFORMING HYBRID BEAMFORMING IN WIRELESS COMMUNICATION SYSTEM

摘要

One or more embodiments provides a precoder selection method for performing hybrid beamforming in a wireless communication system. The method includes selecting a predetermined number of candidate transmit beams using a signal strength received through each of first combinations with receive beams that can be mapped to each transmit beam of each of transmit antennas mounted on a transmitter. The method also includes selecting a precoder using signal strength received through each of second combinations with receive beams that can be mapped to each of the candidate transmit beams.
