1. A communication device, comprising:

  • an antenna;

    a radio circuitry, coupled to the antenna, that is operative to transmit a first signal to at least one additional communication device via the antenna, wherein;

    the first signal indicates a beamforming capability that includes a transmit functionality and a receive functionality corresponding to the 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 radio circuitry, that is operative to calculate an antenna weight vector (AWV) based on a second signal received from the at least one additional communication device, wherein the second signal is received in response to the first signal; and

    wherein;

    a configuration of the antenna is 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 that is configured based on the AWV.
