Unscheduled power save mode with peer device notification

A method comprising:

• receiving, from a network coordinator device of a network, a first acknowledgement of a first request to enter an unscheduled power save mode;
• responsive to receipt of the first acknowledgement of the first request, transmitting, by a device, a first indication of entering the unscheduled power save mode to at least one other device of the network via a peer-to-peer communication;
• entering the unscheduled power save mode responsive to receipt of a second acknowledgment of the first indication from the at least one other device;
• exiting the unscheduled power save mode responsive to receipt, from the network coordinator device, of a third acknowledgment of a second request to exit the unscheduled power save mode;
• transmitting a second indication of exiting the unscheduled power save mode to the at least one other device of the network upon exiting the unscheduled power save mode;
• and
• receiving, from the network coordinator device, a beacon message that indicates that the device exited the unscheduled power save mode, the beacon message being separate from the third acknowledgment of the second request to exit the unscheduled power save mode, wherein the beacon message is received by the at least one other device at least when the at least one other device is not in a power save mode.

A computer program product comprising code stored in a non-transitory computer-readable storage medium, the code comprising:

• code to receive, from a network coordinator device of a network, an acknowledgement of a request to enter an unscheduled power save mode;
• code to transmit, by a device, responsive to receipt of the acknowledgement and prior to entering the unscheduled power save mode, an indication of entering the unscheduled power save mode to at least one other device of the network;
• code to enter the unscheduled power save mode responsive to receipt of another acknowledgement of the indication from the at least one other device;
• code to transmit another indication of exiting the unscheduled power save mode to the at least one other device of the network upon exiting the unscheduled power save mode;
• and
• code to receive, from the network coordinator device, a beacon message that indicates that the device exited the unscheduled power save mode, wherein the beacon message is received by the at least one other device at least when the at least one other device is not in a power save mode.
