APPARATUS AND METHOD FOR UPLINK BEAMFORMING AND SPACE-DIVISION MULTIPLE ACCESS (SDMA) IN MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) WIRELESS COMMUNICATION SYSTEMS

摘要

An apparatus and method for beamforming of a terminal in a Multiple Input Multiple Output (MIMO) wireless communication system are provided. The method includes transmitting sounding signals beamformed through a plurality of beamforming weight vectors in sequence, receiving control information indicative of an uplink weight vector determined by a base station and a maximum channel quality value using the sounding signals and transmitting a transmit signal beamformed with the uplink weight vector via a plurality of antennas.
