摘要： 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.

摘要： A method for determining a loading of a wideband communications channel in a wireless communications system includes: setting up a loading table for the wideband communications channel comprising a plurality of narrow band communications channels; obtaining channel characteristics of the plurality of narrow band communications channels; deciding on a number of data streams and a practical bandwidth of the wideband communications channel for a data transmission transaction and selecting one or more peer communications devices for receiving the data streams; completing the data transmission transaction with the one or more peer communications devices; updating the loading table with the information about the practical bandwidth of the wideband communications channel, the number of data streams and duration of the data transmission transaction; and computing the loading by using the information in the loading table in accordance with a pre-determined formula.
