APPARATUS AND METHOD FOR BEAMFORMING GAIN DIFFERENCE COMPENSATION ACCORDING TO CHANGE OF TRANSMITTING AND RECEIVING BEAM PATTERN IN BEAMFORMING BASED WIRELESS COMMUNICATION SYSTEM

摘要

Provided is a method of operating a terminal device in a wireless communications system using beamforming, which comprises the steps of receiving a reference signal transmitted by using a plurality of downlink transmit beams; measuring channel quality information of the received reference signal; and generating effective channel quality information by compensating for beamforming gain compensation information according to the channel quality information.
