Title: METHOD FOR PERFORMING BEAMFORMING BASED ON PARTIAL ANTENNA ARRAY IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Abstract:
A method for receiving a signal from a base station by a user equipment using beamforming based on a massive antenna array in a wireless communication system is disclosed. The method includes configuring a preferred antenna port set among a plurality of antenna ports included in the massive antenna array, measuring channel state information by receiving a reference signal corresponding to the preferred antenna port set and reporting the channel state information to the base station, and receiving a beamformed signal from the base station using the preferred antenna port set based on the channel state information.
