Abstract: A method for communicating over a WiFi channel. In some embodiments, the method includes determining, by a non-access point station, that a first skipping criterion is met; in response to determining that the first skipping criterion is met, skipping N1 target wait time service periods, N1 being a positive integer; after skipping N1 target wait time service periods, determining, by the non-access point station, whether a second skipping criterion is met; and in response to determining that the second skipping criterion is met, skipping N2 subsequent target wait time service periods, N2 being a positive integer greater than N1.

Abstract: A system and method for dynamic access point (AP) selection by a station (STA) in a coordinated AP group is herein disclosed. According to an embodiment, a STA obtains one or more link quality metrics for each link between the STA and each of a plurality of member APs in the coordinated AP group. The STA dynamically selects at least one anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The at least one anchor AP being used to relay transmission between the STA and a coordinator of the coordinated AP group. Authentication of the STA with the at least one anchor AP is shared with all APs in the coordinated AP group, allowing the STA to utilize any subsequently selected anchor AP to relay transmissions without re-authentication.
