    Abstract: A method of operation of an access point includes transmitting a message via a low-power network, the message indicating one or more network parameters associated with a wireless local area network (WLAN) that is associated with the access point. The method includes performing a setup procedure with a mobile device based on the one or more network parameters. The method further includes, after performing the setup procedure, performing one or more data communications with the mobile device using the WLAN.

    Abstract: Methods, systems, and devices for wireless communication are described. Devices in a wireless network may be grouped into a basic service set (BSS), which may enable coordination of communications within the network. A BSS may have an associated coverage area. Some devices may be operable to communicate using extended range (ER) transmissions, which may increase the size of the coverage area associated with the BSS. In some cases, an access point (AP) may support multiple BSSs with equivalent security profiles. A first BSS may exclusively support ER transmissions, while a second BSS may support non-ER transmissions. Techniques are described for a wireless device to discover one or more of the BSSs associated with a given AP, associate with at least one of the discovered BSSs, and in some cases switch between the BSSs with equivalent security profiles. The discussed techniques may provide more efficient communications in the wireless network.

    Abstract: Aspects of the present disclosure provide techniques for efficient ranging, for example, in a neighbor aware network (NAN). According to certain aspects, an apparatus for wireless communications is provided. The apparatus generally includes a processing system configured to determine a period that at least one second apparatus is scheduled to be awake, generate a first frame for transmission to the second apparatus during the period, determine ranging information based on a time difference between transmission of the first frame and receipt of a second frame in response to the first frame, and generate a third frame including the ranging information; a transmit interface configured to output the first and third frames for transmission; and a receive interface configured to obtain the second frame. By exchanging ranging information in already scheduled wake-up periods and in existing frame, power consumption and signaling overhead may be reduced.

    Abstract: Methods, apparatuses, and devices are described for wireless communications in which neighborhood area network (NaN) information may be requested and provided in a relatively fast and efficient manner between devices of a NaN. A wireless communication device, such as a station in a wireless communications network, may transmit an active probe request to seek information related to a NaN. The active probe request may be a NaN specific probe request, or may be transmitted from a station as part of an active scan for wireless network infrastructure other than NaN devices (e.g., as part of a scan for an AP in a BSS). An AP or master device of the NaN may receive the probe request and generate a NaN discovery response, which may include information that the requesting device may use for connecting to a device in the NaN.

    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

    Abstract: Methods, systems, and devices are described for unicast key management across multiple neighborhood aware network (NAN) data link networks (NDL) comprising: establishing, by a first device, a first association with a second device via a first data link; establishing, by the first device, a second association with the second device via a second data link; and using a single unicast key to encrypt unicast traffic transmitted via the first data link and the second data link between the first device and the second device.

    Abstract: Methods, systems, and devices are described for presence indication and determination in a wireless data link, such as a neighbor aware network (NAN) data link (NDL). A wireless station (STA) may identify a set of devices associated with the wireless data link and transmit a message to the set of devices including a presence request indicator. The STA may determine that a first subset of the set of devices are present in the wireless data link based on receiving a response to the message from the first subset. The STA may also determine that at least one device of the set of devices are absent from the wireless data link based on receiving a notice of absence message from the one device.
