Scheduling for signaling and information transfer

摘要

In a power save scheme, signaling and information transfers are scheduled to increase the amount of time a device in a wireless system can operate in power save mode. Multiple periods of time are allocated for signaling and for information transfer during a beacon interval. Control signaling during a signaling block indicates whether a given device should be awake for an information transfer during a subsequent information transfer period during the beacon interval. Thus, based on the indication, the device determines whether to be awake or asleep during the information transfer period.

主权项

1. An apparatus configured for wireless communication, comprising:
a receiver configured to receive a schedule specifying a plurality of signaling periods and a plurality of information transfer periods within a beacon interval, wherein the schedule is received from a parent apparatus, and further configured to receive a control signal during a particular one of the signaling periods, wherein each of the signaling periods is followed by a respective one of the information transfer periods within the beacon interval; a processing system configured to operate in an active state, after receiving the control signal during the particular signaling period, to transfer information during a particular one of the information transfer periods following the particular signaling period; and a transmitter configured to rebroadcast a service set identifier of the parent apparatus.
