Abstract:
Systems and methods are provided for determining, at a beamformee, to transmit data signals from transmitting spatial streams at one or more beamformers. Next, a gain resulting from an uplink transmit beamforming protocol may be determined to exceed an overhead of the transmit beamforming protocol. In response to the determination, the uplink transmit beamforming protocol may be conducted. This protocol includes, transmitting trigger frames to the beamformers to obtain channel data regarding channels between each of the transmitting antennae and the active receiving antennae, receiving responses to the trigger frames from each of the beamformers, generating the channel data based on the received responses, feeding back the channel data to each of the beamformers, scheduling the uplink transmit beamforming protocol based on the channel data, and receiving an integrated data signal from the beamformers based on a processing of the data signals via the uplink transmit beamforming protocol.
