Apparatus and method for supporting multi-antenna transmission in beamformed wireless communication system
First Claim
1. A method for operating a transmit end of a wireless communication system, the method comprising:
- determining at least one transmit (Tx) beam pattern based on receive (Rx) beamforming capability information of a receive end and channel information between the transmit end and the receive end; and
transmitting 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.

Abstract
An apparatus and method for supporting diversity in a beamformed wireless communication system. A method for transmitting a signal in a transmit end includes determining Receive (Rx) beamforming capability information of a receive end, receiving channel information on at least one Transmit (Tx) beam pattern from the receive end, determining at least one Tx beam pattern for transmitting a signal to the receive end, in consideration of Rx beamforming support information of the receive end and the channel information on the at least one Tx beam pattern, and transmitting a signal to the receive end using the at least one Tx beam pattern for transmitting the signal to the receive end.
