Abstract: In a power control method in a wireless local area network, a beamformer sends a null data packet (NDP) via a plurality of spatial streams to beamformees. After receiving the NDP, a beamformee determines a first parameter for power control based on RSSIs of a plurality of receive antennas when the beamformee receives the NDP, or based on SNRs of a plurality of spatial streams when the beamformee receives the NDP. The beamformee then generates a beamforming report comprising the first parameter, and sends the beamforming report to the beamformer.
