1. An apparatus comprising:

  • a memory; and

    a processor configured to cause an initiator station (STA) of a Beamforming (BF) training to;

    transmit to a responder STA a plurality of initiator BF training frames during one or more repetitions of a Transmit (Tx) Sector Sweep (TxSS) over a plurality of antennas of the initiator STA, a count of the one or more repetitions of the TxSS is based on a count of antennas of the responder STA, an initiator BF training frame of the plurality of initiator BF training frames comprising an antenna identifier to identify an antenna of the initiator STA to transmit the initiator BF training frame, and a sector identifier to identify a sector of the initiator STA to transmit the initiator BF training frame;

    after the one or more repetitions of the TxSS, receive at least one responder BF training frame from the responder STA, the responder BF training frame comprising an indication of a responder-identified antenna of the initiator STA and a responder-identified sector of the initiator STA; and

    based on the at least one responder BF frame, determine an antenna setting to communicate with the responder STA.
