In accordance with at least some embodiments, a system comprises an access point and a station in communication with the access point. The station has at least two network technology subsystems subject to coexistence interference. The station selectively implements bounded Power Save (PS)-Polling (BPS) logic to handle communications between the station and the access point. The BPS logic operates to confine PS-Poll transmissions starts to one of two separate windows during a medium grant duration of the station.
