Abstract
Refining beamforming techniques for use in a communication system. In one embodiment, a method for beamforming in a communication system includes generating multiple training signals to be transmitted via multiple antennas over a communication channel, including applying a different antenna weight vector (AWV) to each of the multiple training signals. The method further includes receiving feedback generated using the multiple training signals, where the feedback includes a transmitter AWV for use with the multiple antennas and/or channel state information (CSI) descriptive of the communication channel.
