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.

Abstract: A device may join an existing mesh network by authenticating with only one of a plurality of member devices of the existing mesh network. Once the device has successfully authenticated with the only one member device, the device may receive a common group key. The device may send a route request message encrypted with the common key to one or more of the plurality of member devices of the existing mesh network. In response, the device may receive one or more route reply messages encrypted with the common key from one or more of the plurality of member devices of the existing mesh network. The device may determine an optimal route to one or more provider member devices of the existing mesh network based on the received route reply messages.

Abstract: Methods, systems, and devices are described for communications via a mesh network. To join an existing mesh network, a wireless communication device may identify a member device from a plurality of member devices of an existing mesh network. The wireless communication device may communicate with the identified member device to participate in a single authentication procedure. Upon successfully completing the single authentication procedure, the wireless communication device may join the existing mesh network without needing any additional authentication procedures with another member device of the plurality of member devices to join the existing mesh network. This approach may be used for any mesh network, such as a social Wi-Fi mesh network.

Abstract: Techniques for improved spatial reuse for wireless local area network (WLAN) networks are described. An access point (AP) may win a contention to a wireless medium and obtain a transmission opportunity (TXOP). The AP may perform a procedure to identify a group of un-managed APs for participation in spatial reuse opportunities for synchronous transmission over the TXOP. The AP may perform the procedure using over-the-air signaling. The AP may transmit a spatial reuse (SR) poll frame to one or more un-managed APs of the network, either sequentially or as part of a multiple- AP procedure. The AP may receive an SR response frame, or directly measure potential interference of a station (STA) serviced by one or more un-managed APs, and select a group of APs for coordinated reuse over the TXOP. The AP may select the group of APs based on one or more criteria for coordinated reuse.

Abstract: An access point (AP) may determine a time resolution for values indicative of wakeup signal transmission times based on a wakeup schedule of a station (STA) and a clock drift value for the STA and may transmit, to a primary radio of the STA, an indication of the time resolution. The AP may identify a transmission time of a wakeup signal for the STA and determine a value indicative of the transmission time. The AP may transmit, to a wakeup radio of the STA, the wakeup signal as a packet that includes the value indicative of the transmission time. The STA may determine the transmission time of the wakeup signal based on the wakeup schedule, the indication of the time resolution, and the value indicative of the transmission time and may update a local clock timing based on the transmission time.

Abstract: A wireless device may dynamically activate and/or inactivate wireless links for multi-link communications. A transmitting wireless device may indicate one or more wireless links to be activated by a receiving wireless device to receive subsequent multi-link transmissions. The indication may be sent over an anchor wireless link, such that the receiving wireless device may monitor the anchor wireless link, with other wireless links in an inactive or low power state, until an indication is received to activate additional wireless links. The receiving wireless device may then activate wireless links identified by the received indication, and receive data from the transmitting device via the multiple links. The activated wireless links may be inactivated upon expiration of a time duration or upon receiving a second indication to inactivate the active links. That is, indications communicated over an anchor wireless channel may identify other wireless links to be activated, inactivated, or maintained.

Abstract: Methods, systems, and devices are described for improving system throughput by reducing contention in a peer-to-peer (P2P) data link network. Specifically, the present disclosure provides a method of ordering data transmissions in a data transmission window based on an order of traffic announcement messages in a corresponding paging window. Moreover, a wireless station of the P2P data link network may reserve portions of a shared wireless medium for transmissions of other wireless stations belonging to the same P2P data link network and preventing transmission of out-of-network wireless stations.

Abstract: Methods, systems, and devices related to wireless communication via a mesh network are described. In particular, the disclosure is directed to selecting a path between two nodes in a wireless mesh network based on consideration of type of data requested and a determination whether an intermediate node, within a predetermined range of the requesting node, is actively broadcasting the requested data. Such opportunistic consideration in selecting a path between two nodes may avoid unnecessary activation of additional broadcasting nodes and reduce the risk of triggering interference between multiple nodes broadcasting duplicate data.

Abstract: Methods, systems, and devices for wireless communication are described. Stations within a neighborhood awareness network (NAN) may determine when to transmit synchronization beacons during a wake-up time based on some priority (e.g., stations with more recent clock updates or earlier time stamps, stations communicating with a larger number of peers or associated with a larger number of NAN device links (NDLs), etc. may transmit beacons earlier in a wake-up window or with a higher probability). Other stations within the NAN may maintain clock synchronization based on the transmitted beacons (e.g., that include recently updated clock information). Additionally or alternatively, a station may signal other stations within a NAN when the station detects disappearance of synchronization beacons (e.g., or loss of clock synchronization). In some cases, the signaling may include requests for the one or more other stations to start or stop beacon transmissions as desired.
