EFFICIENT AND FLEXIBLE TRANSMIT BEAMFORMING SECTOR SWEEP IN MULTI-ANTENNA COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for removing redundancy of beamforming training transmissions and/or reducing delays caused by beamforming training.SOLUTION: Each beacon data unit in a plurality of beacon data units includes an indication that the beacon data unit can be used for transmit beamforming training. When a first beamforming training transmission corrupted by a collision is received, a first station to which the first beamforming training transmission corresponds is determined based on the first beamforming training transmission corrupted by the collision. In response to determining the first station, a signal is transmitted to the first station to prompt the first station to transmit a second beamforming training transmission.
