Access Point Configured For Unavailability Advertisement With Target Wake Up Time (Twt)

Abstract: An access point (AP) operating as a Target Wake-up Time (TWT) scheduling AP may encode a broadcast TWT element for transmission to advertise a broadcast TWT with one or more broadcast TWT Service Periods (SPs). When the broadcast TWT element carries one or more broadcast TWT parameter set fields with a broadcast TWT ID subfield equal to zero and has a Responder Power Management (PM) Mode subfield equal to one, the AP may set a NDP Paging Indicator/Unavailability Mode subfield of a Control Field of the broadcast TWT element to a value of zero to indicate that the AP is unavailable outside of the one or more broadcast TWT SPs except for other TWT SPs that are setup with the AP or advertised by the AP. The AP may set the NDP Paging Indicator/Unavailability Mode subfield of the Control field to a value of one to indicate that the AP is unavailable outside of the one or more broadcast TWT SPs including unavailable during any time that falls within the other TWT SPs that are setup with the AP or advertised by the AP.
