Abstract
A method of downlink multi-sector transmission is provided. An initiator station first performs sector training by transmitting a plurality of sounding signals to a plurality of responder stations in a wireless network. The coverage associated with the initiator station is partitioned into a plurality of sectors, and each sector is covered by a sectorized beam. The initiator station then receives sector ID feedback information from each responder station in response to the sounding signals. The sector ID feedback information indicates preference to each of the sectors from each responder station. Next, the initiator station groups multiple spatially orthogonal responder stations together based on the sector ID feedback information. Finally, the initiator station performs multi-sector transmission by simultaneously transmitting data to the multiple responder stations in different sectors using corresponding sectorized beams.
