1. A method for communication in a WLAN, comprising:associating a client station (STA) with a basic service set (BSS) of a first access point (AP), having first antennas, in a wireless local area network (WLAN); synchronizing a second AP, having second antennas, in the WLAN with the first AP;
computing distributed beamforming parameters over a group of the first antennas and the second antennas;
distributing data for transmission to the STA to both the first AP and the second AP; and
transmitting the distributed data to the STA from the first AP via the first antennas in the group and the second AP via the second antennas in the group in synchronization in accordance with the distributed beamforming parameters.
