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.
