Patent ID: 8126406

Claim:
A method, comprising: receiving a plurality of beams from a first transceiver via a plurality of transmission channels; evaluating characteristics of the plurality of beams received at a second transceiver; deriving beamforming information to be fed back from the second transceiver to the first transceiver based on the characteristics, wherein the beamforming information is usable for controlling, at the first transceiver, a transmission of the plurality of beams; selecting at least a first and a second set of beamforming information to be fed back from the second transceiver via a feedback path to the first transceiver, and wherein the selecting, at the second transceiver, further comprises projecting the second set of beamforming information to nullspace of the first set of beamforming information, and feeding back the first set of beamforming information and the projection of the second set of beamforming information to the nullspace of the first set of beamforming information to the first transceiver.
