Millimeter-wave communication station and method for scheduling association beamforming training with collision avoidance

摘要

Embodiments of a millimeter-wave communication station and method for scheduling association beamforming training (A-BFT) with collision avoidance are generally described herein. In some embodiments an initiating station transmits a transmit sector-sweep frame in each of its antenna sectors and receives a reverse transmit sector-sweep frame from two or more unassociated responding stations. The initiating station transmits a sector-sweep feedback frame to each of the responding stations to indicate whether each responding station is to perform beamforming training in a current beacon interval or a subsequent beacon interval. The sector-sweep feedback frame may indicate an order in which the responding stations are to perform beamforming training in subsequent beacon intervals.

1. A method performed by an initiating station for scheduling association beamforming training (A-BFT) for unassociated stations in a millimeter-wave communication network, the method comprising:
transmitting a transmit sector-sweep frame in each of a plurality of antenna sectors; receiving a reverse transmit sector-sweep frame from two or more unassociated responding stations; and transmitting a sector-sweep feedback frame to each of the responding stations from which the reverse transmit sector-sweep frames were received, wherein the sector-sweep feedback frames indicate whether each responding station is to perform beamforming training in a current beacon interval or a subsequent beacon interval; further wherein the sector-sweep feedback frame indicates an order in which the responding stations are to perform beamforming training in subsequent beacon intervals.
