Title: BEAM INFORMATION REPORTING METHOD FOR MULTI-USER MIMO TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Abstract:
Disclosed is a method by which a terminal reports beam information to a base station in a wireless communication system. The method comprises the steps of: receiving, from the base station, a beam measurement reference signal corresponding to each of a plurality of candidate transmission beams; determining at least one best transmission beam among the plurality of candidate transmission beams on the basis of the beam measurement reference signal; determining at least one worst transmission beam corresponding to each of the at least one best transmission beam among the plurality of candidate transmission beams by using a best reception beam corresponding to the at least one best transmission beam among candidate reception beams; reporting, to the base station, information on the at least one best transmission beam and the at least one worst transmission beam corresponding to the at least one best transmission beam.
