Abstract: Various embodiments may be generally directed to antenna array weight vector selection techniques for 60 GHz multiple-input multiple-output (MIMO) communications. In some embodiments, using one or more such techniques, a 60 GHz-capable transmitting device may select respective antenna array weight vectors for two or more transmit antenna arrays, and a 60 GHz-capable receiving device may select respective antenna array weight vectors for two or more receive antenna arrays. In various embodiments, in order to obtain information for use in selecting such antenna array weight vectors, the transmitter and receiver may utilize one or more existing beamforming training algorithms defined for 60 GHz single-input single-output (SISO) communications. In some embodiments, for example, the transmitter and receiver may utilize one or more beamforming training algorithms defined in IEEE 802.11ad-2012. The embodiments are not limited in this context.

Abstract: Various embodiments are generally directed to an apparatus, method and other techniques to perform beamforming training in a MIMO environment. Some embodiments may include communicating one or more beamforming refinement packets having training subfields with orthogonal structures such that devices may simultaneously perform beamforming training for each pair of phased array antennas. Embodiments may also include the beamforming refinement packets with channel estimation fields with orthogonal structures.

Abstract: Disclosed herein are techniques to provide an indication of bandwidth to establish a TxOP using channel bonding. An information element may be generated to include an RTS frame or a CTS frame and an indication of bandwidth in a parity portion of the information element. The indication of bandwidth may be included by using 16 bits of the parity bits of parity bytes for a PHY header of the information element.
