METHOD FOR DETERMINING WEIGHT FOR BEAMFORMING IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

A method for a base station to determine a weight for hybrid beamforming in a wireless communication system according to an embodiment of the present invention is configured for repeated transmission of a first omni-directional beam that is uniformly formed in all directions. signaling to the terminal; receiving the first omni-directional beam from the terminal by forming a second omni-directional beam; repeatedly receiving the first omni-directional beam from the terminal by sequentially forming a plurality of directional beams corresponding to a plurality of directions; and a weight for hybrid beamforming based on a difference in gain between the first omni-directional beam received through the second omni-directional beam and the first omni-directional beam received through a first directional beam among the plurality of directional beams including the step of determining
