Methods, systems, and devices for wireless communication are described. A first wireless device may establish a communication session with a second wireless device using a neighbor awareness networking (NAN) radio access technology (RAT). The first wireless device may transmit a first indication that the first wireless device is capable of using a secured ranging protocol. The first wireless device may receive a second indication that the second wireless device is also capable of using the secured ranging protocol. The first wireless device may determine one or more setup parameters to use for a ranging procedure between the first wireless device and the second wireless device based on the first indication and the second indication. Accordingly, the first wireless device may obtain a measurement report after using the secured ranging protocol to perform the ranging procedure in accordance with the one or more setup parameters.

Methods, systems, and devices are described for peer-to-peer (P2P) group owner (GO) multi-channel concurrent (MCC) operation and an associated absence period indication for legacy client devices. In some aspects, an absence period during which a peer-to-peer (P2P) group owner (GO) is unavailable to receive transmissions from client devices wirelessly coupled with the P2P GO may be identified. A notice of absence (NoA) may be transmitted by the P2P GO, the P2P NoA indicating the absence period if the client devices wirelessly coupled with the P2P GO include a P2P client device that supports a P2P protocol. A legacy wireless beacon may be transmitted by the P2P GO, the legacy wireless beacon comprising an information element (IE) indicating the absence period if the client devices wirelessly coupled with the P2P GO include a legacy client device that does not support the P2P protocol.

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.

Power management for WLAN client devices using low energy signaling

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.

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

This disclosure describes systems and methods for implementing power save modes of operation while maintaining a WLAN communications link. The techniques of the invention involve coordinating power save mode periods between the participating devices by through the use of a Peer Power Save Information Element (PPS IE) included in the beacon frame transmitted by one of the devices. The PPS IE may include an Enabled/disabled bit, a PPS Count value and a PPS Duration. The PPS Count may be decremented from an initial value after each beacon transmission until the count reaches zero, at which point the device may be configured to enter power save mode for the period indicated by the PPS Duration. During power save mode, the device may track the duration and awaken after the corresponding period of time to begin transmitting and receiving beacons again.
