Abstract:
A first communication device receives a plurality of training signals associated with a transmit beamforming training portion of a current iteration of a beamforming procedure between the first communication device and a second communication device. A receive antenna weight vector (AWV) is applied to an antenna array as each of the plurality of training signals is received. A channel estimate is determined based on reception of the plurality of training signals, and feedback is determined based on the channel estimate. The feedback is transmitted to the second communication device as part of the current iteration of the beamforming procedure.
