Systems and methods for coordinating power save operations in an ad hoc network

摘要

Systems and methods are disclosed for facilitating coordination among member stations in an IBSS to allow members to remain in a power save mode of operation for extended periods of time without awakening to transmit or receive beacons at each scheduled TBTT. A power save initiator may establish a power save period during which all nodes in the network may enter a power save mode. Correspondingly, beacons may not be sent during the extended power save period and any traffic to be exchanged between members of the IBSS WLAN may be buffered for delivery after the extended power save period ends.

主权项

1. A method for operating an independent basic service set (IBSS) for a plurality of stations, the method being performed by a power save initiator within the IBSS and comprising:
determining scheduled target beacon transmission times (TBTTs) at which one or more of the plurality of stations are scheduled to transmit beacons; detecting a trigger condition for entering an extended power save period, wherein a duration of the extended power save period is greater than a TBTT period; upon detecting the trigger condition, signaling the extended power save period to the plurality of stations to prevent the stations from transmitting beacons during one or more of the scheduled TBTTs; operating in a power save mode for the extended power save period, wherein the extended power save period causes the power save initiator to remain in the power save mode during the one or more scheduled TBTTs; and returning to an active mode after the extended power save period has elapsed.
