Unscheduled peer power save mode

摘要

Embodiments of unscheduled peer power save systems, devices and methods are disclosed. For example, a method of saving power for nodes configured to communicate via a direct link is provided. In one embodiment, among others, the method comprises forming, at an access point node (AP node), a indication frame for a client node, when no service period has occurred for the client node for a period of time at least equal to an indication window; sending the formed indication frame from the AP node to the client node through an access point; receiving, at the client node, the peer traffic indication from the access point; and determining, at the client node, that the AP node has traffic to send to the client node based on the indication frame.

1. A method, comprising:
receiving, at a second station, a first frame from a first station, the first frame having a power management (PM) bit equal to 1; and responsive to receiving the first frame, suspending, at the second station, direct transmissions to the first station until the occurrence of a first service period, wherein the first service period is triggered by a first indication frame transmitted by the second station to the first station via an access point (AP) when no data has been exchanged between the first station and the second station for a period of time at least equal to an indication window, and wherein the first and second stations are configured to communicate via a direct link or via the access point.
