Abstract:
Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may include a used basic service set (BSS) color in a downlink physical layer convergence procedure protocol, data unit (PPDU). The used BSS color may indicate communication between the AP and associated STAs. The AP may detect another PPDU from an STA that is un associated with the AP. If a header portion of the detected PPDU includes the used BSS color, the AP may: determine an alternate BSS color, and transmit a color switch announcement (CSA) element that indicates the alternate BSS color. The CSA element may be configurable to further indicate whether the AP and the associated STAs are to switch, from the operating channel to an alternate channel for the communication.
