Abstract: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.

Abstract: Systems and methods for partitioning radio spectrum in an AP to support a mixed client environment while maintaining efficient 802.11ax transmissions is provided. Clients in a zone may be categorized into 802.11ax and legacy clients, and those clients may further be categorized into a majority population and a minority population. Assignment of the minority and majority populations can be effectuated by considering the number of available channels to be assigned to each population of client devices, as well as steering load/cost and a client device's ability to be steered to another channel. Moreover, assignment of the minority and majority populations can take into account maintaining a particular client-channel density.
