METHOD AND APPARTUS FOR MULTIUSER BEAMFORMING IN WIRELESS COMMUNICATION SYSTEMS

摘要

The present invention relates to multiuser beamforming in wireless communication systems. An operation method of a control node in wireless communication systems comprises the steps of: transmitting control information regarding beam refinements for a plurality of terminals; and transmitting frames for the beam refinements; wherein the frames are subjected to transmission beamforming via at least one beam, and the at least one beam comprises optimum transmission beams of the terminals.
