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 using a large-scale antenna array-based beamforming of the base station in a wireless communication system is provided. Receiving antenna shuffling information corresponding to a set of preferred antenna ports among a plurality of antenna ports included in the large-scale antenna array from the base station; and channel state information based on the antenna shuffling information. Calculating and reporting 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, the antenna shuffling information Includes at least one of information on an antenna port start index included in the preferred antenna port set and information on an antenna port index allocation direction.
