Abstract:
A method and system for communicating feedback information in a multiple user multiple input multiple output (MU-MIMO) communication system are presented. In one aspect of the method and system, a beamformer station may communicate a feedback information request to a plurality of beamformee stations. The feedback information request may request feedback data for a plurality of RF channel bands. The RF channel bands may form a multichannel. The beamformer may subsequently transmit a plurality of signals utilizing the RF channel bands within the multichannel. Each of the beamformees may receive the plurality of subsequently transmitted signals. A beamformee may generate the requested feedback data for each RF channel band within the multichannel. The beamformee may generate a beamforming report, which comprises the feedback data, which is generated across the plurality of RF channel bands in the multichannel. The beamformee may transmit the beamforming report to the beamformer.
