Title: BEAMFORMING TRAINING METHOD, STATION AND ACCESS POINT
Abstract:
A beamforming training method comprises: during the beamforming training, a station uses multiple reception antennas to simultaneously receive multiple beacon frames sequentially transmitted by an access point, and a beacon frame corresponds to a sector of a transmission antenna of the access point; the station measures the received signal quality of the beacon frames received by each of the multiple reception antennas, and determines, according to the received signal quality, at least two communication links between the multiple reception antennas of the station and the multiple transmission antennas of the access point, and the access point's target transmission antenna and target sector which correspond to each communication link; different communication links correspond to different transmission antennas and different reception antennas; the station returns the identifications of the target transmission antennas and the identifications of the target sectors to the access point. By employing the present invention, the selection of the antenna modes corresponding to the multiple communication links between the access point and the station can be implemented.
