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.

Abstract: An AID allocation method for a multi-link device, includes: An access point multi-link device generates and sends a first frame. Correspondingly, a station device receives and parses the first frame to obtain an AID that is allocated to the station device and carried in the first frame. The AID is neither a BSSID that can be supported by a first-type access point in the access point multi-link device nor an identifier of an access point in the access point multi-link device. The first-type access point is an access point for establishing a link between the station device and the access point multi-link device.
