Method for performing antenna shuffling using partial antenna array based beamforming in wireless communication system, and apparatus therefor

摘要

A method for receiving a signal from a base station by a user equipment, using massive antenna array based beamforming of the base station in a wireless communication system is disclosed. The method includes receiving, from the base station, antenna shuffling information corresponding to a preferred antenna port set among a plurality of antenna ports included in the massive antenna array, measuring channel state information according to the antenna shuffling information and reporting the channel state information to the base station, and receiving, from the base station, a beamformed signal using the preferred antenna port set based on the channel state information, wherein the antenna shuffling information includes at least one of information about a start index of antenna ports included in the preferred antenna port set and information about a direction to which antenna port indexes are allocated.
