Abstract

Embodiments of a station (STA) and method of beam refinement are generally described herein. The STA may transmit a beam refinement protocol (BRP) frame for a beam refinement of a first transmit direction to a second transmit direction by a responding STA. At least a portion of the BRP frame may be transmitted in the first transmit direction. The STA may receive a response frame from the responding STA that indicates the second transmit direction. The BRP frame may include an enhanced directional multi-gigabit (EDMG) Header-A field and at least one training unit. The training unit may comprise a configurable first number of training sequences for channel estimation by the responding STA followed by a configurable second number of training sequences for the beam refinement. The EDMG Header-A field may indicate the first and second numbers.
