Claim:
1. A method for a coordinated beamforming for overlapping basic service sets (OBSSs) in wireless local area network (WLAN), the method comprising: deciding, by an access point (AP), to participate in the coordinated beamforming for the OBSSs, wherein the OBSSs comprise a plurality of APs and a plurality of stations (STAs) associated with the APs, wherein each AP is associated with more than one STA; and transmitting, by the AP, a coordinated beamforming (CB) announcement message indicating an identifier (ID) of the AP and an ID of each station (STA) associated with the AP to the other APs of the OBSSs so that the other APs adjust their beamforming to their associated STAs based on the CB announcement message.
