Abstract: Methods, systems, and devices are described for using low energy (LE) signaling to indicate to a wireless station (STA), prior to transmission of a beacon, whether the beacon will further indicate that an access point (AP) has data to transmit to the STA. In one aspect, a method may include receiving, using a first radio of a wireless STA using a LE communication protocol, a first signal comprising an indication of a traffic indication map (TIM) of a wireless local area network (WLAN) beacon, and selectively powering up a second radio of the wireless STA to receive the WLAN beacon in response to the indication. In one aspect, the wireless STA may power up the first radio at a predetermined interval prior to a target beacon transmission time (TBTT) of the WLAN beacon.

Abstract: 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.

Abstract: A method and apparatus are disclosed for reducing power consumption of wireless devices operating in a wireless network. In one embodiment, a first wireless device may operate in low-power mode and receive a BLUETOOTH low energy (BLE) message from a second wireless device. The first wireless device may leave the low-power mode and enter a normal operating mode based, at least in part, on the BLE message. In some embodiments, the BLE message may include informational elements that the first wireless device may use to determine whether to remain in or leave the low-power mode. In some other embodiments, the BLE message may be synchronized to a Wi-Fi message, such as a Wi-Fi beacon. In at least one embodiment, the first wireless device may stop scanning for wireless networks when in the low-power mode.
