Abstract
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.
Claims28
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.
A method of communication by an apparatus, comprising:
- receiving, by the apparatus from a parent apparatus, a schedule specifying a plurality of signaling periods and a plurality of information transfer periods within a beacon interval, wherein each of the signaling periods is followed by a respective one of the information transfer periods within the beacon interval;
- receiving, by the apparatus, a control signal during a particular one of the signaling periods;
- after receiving the control signal during the particular signaling period, operating, by the apparatus, in an active state to transfer information during a particular one of the information transfer periods following the particular signaling period;
- and
- rebroadcasting a service set identifier of the parent apparatus.
An apparatus configured for wireless communication, comprising:
- a processing system configured to define a schedule specifying a plurality of signaling periods and a plurality of information transfer periods within a beacon interval, and further configured to determine that another apparatus is to operate in an active state to transfer information during a particular one of the information transfer periods that follows 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;
- and
- a transmitter configured to transmit a control signal to the other apparatus during the particular signaling period as a result of the determination and to rebroadcast a service set identifier of a parent apparatus, wherein the apparatus is associated with the parent apparatus.
A method of communication, comprising:
- defining a schedule specifying a plurality of signaling periods and a plurality of information transfer periods within a beacon interval, wherein each of the signaling periods is followed by a respective one of the information transfer periods within the beacon interval;
- determining that an apparatus is to operate in an active state to transfer information during a particular one of the information transfer periods that follows a particular one of the signaling periods;
- as a result of the determination, transmitting a control signal to the apparatus during the particular signaling period;
- and
- rebroadcasting a service set identifier of a parent apparatus, wherein the apparatus is associated with the parent apparatus.
