摘要：
An access point receives uplink transmissions from client stations using directional antenna beams. The directional antenna beams are generated by an antenna array. The different directional antenna beams are assigned beam identification numbers, and a preferred antenna beam is selected for each client station. The client stations in the different antenna beam regions initiate their uplink transmissions using assigned backoff slots within the contention window. The access point selects the preferred directional antenna beam corresponding to the directional antenna beams assigned to the backoff slots.
