As shown in FIG. 1B, the scheduling of the radio medium can be affected by the presence of another AP 104 that is part of another BSS 100. A STA 106 can be associated with BSS 100b and communicating with AP 2c 104g. If both AP 1c 104c and AP 2c 104g are sending signals on the same RUs at the same time, then the STA 106 may experience collisions or interference that prevents the successful reception of a signal from AP 2c 104g. Thus, controller 1 101a and controller 2 101b can effect a master/slave relationship to schedule the medium for the APs 104.
A configuration of an AP 104 may be as shown in FIG. 2. The AP 104 can include one or more of, but is not limited to, an interference detector 204, a handshake processor 208, a time synchronizer 212, a slave/master elector 216, an AP interface and analysis component 220, and/or a resource unit (RU) assigner 224. There may be more or fewer components than that shown in FIG. 2.
