Apparatus, system and method of beamforming training
First Claim
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.

Abstract
Some demonstrative embodiments include devices, systems and/or methods of wireless communication via multiple antenna assemblies. For example, a device may include a wireless communication unit to transmit and receive signals via one or more quasi-omnidirectional antenna assemblies, wherein the wireless communication unit is to transmit, via each quasi-omnidirectional antenna assembly, a plurality of first transmissions, to receive, in response to the first transmissions, a plurality of second transmissions from another device via one or more of the quasi-omnidirectional antenna assemblies, and, based on the second transmissions, to select at least one selected transmit antenna assembly for transmitting to the other device and a selected receive antenna assembly for receiving transmissions from the other device. Other embodiments are described and claimed.
