Apparatus and method for supporting multi-antenna transmission in beamformed wireless communication system

An apparatus in a transmit end of a wireless communication system, the apparatus comprising:

• a beam setting unit configured to determine at least one transmit (Tx) beam pattern based on the receive (Rx) beamforming capability information of a receive end and channel information between the transmit end and the receive end;
• and
• a transmitter configured to transmit a signal to the receive end using the at least one Tx beam pattern,
• wherein the Rx beamforming capability information comprises at least one of:
• Rx beamforming support or non-support of a receive end, a number of Rx beam patterns supportable by the receive end, concurrent usability or non-usability of a plurality of Rx beams, a number of Rx beams concurrently usable by the receive end, and a number of multiple antenna streams usable by the receive end.
