Abstract:
1. A communication device, comprising: an antenna; a radio circuitry, coupled to the antenna, that is operative to transmit a first signal to establish beamforming during a period initiated under at least one of a contention access period and a channel time allocation period to at least one additional communication device via the antenna using a beamforming training protocol based on a device class of the communication device and/or the at least one additional communication device, the first signal indicating a beamforming capability that declares a transmit functionality and a receive functionality corresponding to the communication device, the first signal for establishing a configuration of the antenna based at least in part on a common beamforming capability with the at least one additional communication device; and the first signal is transmitted in accordance with the transmit functionality corresponding to the communication device; and an antenna weight vector circuitry, coupled to the radio circuitry, that is operative to calculate an antenna weight vector (AWV) based on the transmit functionality corresponding to the communication device and on a second signal, responsive to the first signal, received from the at least one additional communication device, the second signal indicating a beamforming capability that includes a receive functionality corresponding to the at least one additional communication device; the configuration of the antenna modified based on the AWV; and the radio circuitry is operative to transmit data to the at least one additional communication device via the antenna modified based on the AWV.
