Abstract

Systems, methods, and instrumentalities are described to implement an interference management method in a WLAN. An access point (AP) or an inter-BSS coordinator (IBC) may identify a station (STA) associated with a first basic service set (BSS) as an edge STA or a non-edge STA. The AP or the IBC may group the edge STA into an edge group and a non-edge STA into a non-edge group. The AP or the IBC may receive information associated with a second BSS. The AP or the IBC may coordinate access of the edge group and/or the non-edge group. The access may be coordinated to minimize interference of the edge STA. The access may be based at least on the received information associated with the second BSS. The AP or the IBC may adjust transmit power of a plurality of STAs identified as edge group STAs and non-edge group STAs.
