Abstract:
Systems and techniques for interference avoidance beamforming transmissions are described. A described technique includes accessing, at a first device, data for transmission to a second device; performing, at the first device, a channel sounding process with a third device to obtain channel feedback regarding a wireless channel between the first device and the third device; determining a steering matrix based on the channel feedback to reduce interference leakage received by the third device during a beamforming transmission from the first device to the second device; and performing, at the first device, the beamforming transmission to the second device based on the data and the steering matrix.
