Abstract
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques that may help optimize scheduling target wake-up times (TWTs) of wireless nodes.
Claims19
An apparatus for wireless communications, comprising:
- a processing system configured to generate one or more first frames that, collectively, include a set of parameters defining at least one broadcast target wake-up time (TWT) schedule and an assignment of one or more wireless nodes to one or more TWT groups to be serviced in different TWT service periods (SPs) associated with the at least one broadcast TWT schedule wherein the processing system is further configured to generate at least one second frame comprising an indication, for each of the TWT SPs, of one or more wireless nodes of a TWT group to be serviced;
- a first interface configured to output the one or more first frames for transmission, the first interface being further configured to output the at least one second frame for transmission;
- and
- a second interface configured to obtain at least a third frame from one of the one or more wireless nodes of the TWT group to be serviced, in response to the at least one second frame;
- and
- wherein the processing system is further configured to service wireless nodes from which third frames are received by the apparatus.

An apparatus for wireless communications, comprising:
- a processing system configured to generate one or more first frames that, collectively, include a set of parameters defining at least one broadcast target wake-up time (TWT) schedule and an assignment of one or more wireless nodes to one or more TWT groups to be serviced in different TWT service periods (SPs) associated with the at least one broadcast TWT schedule, wherein the processing system is further configured to generate at least one second frame comprising an indication, for each of the TWT SPs, of one or more wireless nodes of a TWT group to be serviced;
- and
- a first interface configured to output the one or more first frames for transmission, the first interface being further configured to output the at least one second frame for transmission;
- and
- wherein the processing system is further configured to decide to provide the indication of which one or more wireless nodes of the TWT group are to be serviced in a discovery frame based, at least in part, on alignment of discovery frames with broadcast TWT service periods.

An apparatus for wireless communications, comprising:
- a first interface configured to obtain one or more first frames from a wireless node that, collectively, include a set of parameters defining at least one broadcast target wake-up time (TWT) schedule and an assignment of the apparatus to at least one TWT group to be serviced in TWT service periods (SPs) associated with the at least one broadcast TWT schedule;
- and
- a processing system configured to cause the apparatus to exit a first state before or during a TWT SP, based on the broadcast TWT schedule and the assignment, wherein:
- the first interface is further configured to obtain, after exiting the first state, at least a second frame comprising an indication of whether or not the apparatus is to be serviced;
- each of the at least second frame is a discovery frame when aligned with one of the TWT SPs;
- and
- the processing system is further configured to re-enter the first state if the second frame indicates the apparatus is not to be serviced.
4 more elements
A wireless station, comprising:
- a processing system configured to generate one or more first frames that, collectively, include a set of parameters defining at least one broadcast target wake-up time (TWT) schedule and an assignment of one or more wireless nodes to one or more TWT groups to be serviced in different TWT service periods (SPs) associated with the at least one broadcast TWT schedule wherein the processing system is further configured to generate at least one second frame comprising an indication, for each of the TWT SPs, of one or more wireless nodes of a TWT group to be serviced;
- and
- a transmitter configured to transmit the one or more first frames, the transmitter being further configured to output the at least one second frame for transmission;
- and
- a receiver configured to receive at least a third frame from one of the one or more wireless nodes of the TWT group to be serviced, in response to the at least one second frame;
- and
- wherein the processing system is further configured to service wireless nodes from which third frames are received by the wireless station.
