Abstract

A method for communication in a wireless local area network (WLAN) includes receiving, at first and second access points (APs) in the WLAN, uplink signals from a first client station (STA), which is associated with a basic service set (BSS) of the first AP. First downlink signals are transmitted from the first AP to the first STA using a first steering matrix. Responsively to the received uplink signals, a second steering matrix is computed, having a null in a direction of the first STA. Second downlink signals are transmitted from the second AP to a second STA in the WLAN using the second steering matrix.
