Abstract
Disclosed are a communication method and a communication apparatus using multiple antennas in a wireless communication system. A communication method of a receiver comprises receiving reference signals from a transmitter of the communication system through beams to which the hybrid beamforming is applied; selecting at least one analog beam having a quality equal to or higher than a preset threshold value among analog beams belonging to the beams, based on the reference signals; and selecting at least one digital beam corresponding to the at least one analog beam and having a quality equal to or higher than the preset threshold value among digital beams belonging to the beams, based on the reference signals. Thus, performance of the communication system can be improved.
