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 a base station in a wireless communication system is disclosed. In particular, the method includes receiving antenna shuffling information corresponding to a set of preferred antenna ports from a plurality of antenna ports included in the large-scale antenna array from the base station; Calculating channel state information according to the antenna shuffling information and reporting to the base station; And receiving a beamformed signal from the base station using the set of preferred antenna ports based on the channel state information, wherein the antenna shuffling information includes a start index of an antenna port included in the preferred antenna port set And information on a direction in which an antenna port index is allocated.
