    Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may be configured to perform a method to accelerate discovery of a peer device after an out-of-band triggering event. For example, a wireless device may detect an out-of-band triggering event and activate a wireless interface capable of peer-to-peer communications in response. The wireless device may transmit one or more discovery messages (e.g., discovery beacons, active subscribe messages, and/or unsolicited publish messages) over the wireless interface immediately after activation of the wireless interface to aid in discovery of the peer device. The one or more discovery messages may be transmitted as service discovery frames. The wireless device may perform service discovery over the wireless interface with the peer device post discovery.

    Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., communication between the mobile stations without utilizing an intermediate access point. Configuration of NAN includes mapping of NAN clusters and multi-hop data routing within a NAN cluster. A wireless device may transmit a subscribe service discovery frame (SDF) to one or more neighboring wireless devices and receive a respective publish SDF from the one or more wireless devices, the respective publish SDF including respective wireless device information. The wireless device may maintain a data structure comprising the respective wireless device information. In some embodiments, the wireless device information may include an address, hop count, and/or service indications, e.g., for data routing and/or service discovery.

    Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. In particular, embodiments described herein relate to techniques for devices (e.g., NAN devices) to propose and confirm schedule updates. The datapath model, and in particular the techniques described herein, may be implemented for unicast and multicast communication between wireless stations.

    Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the mobile stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. In particular, embodiments described herein provide a mechanism for NAN datapaths to support various levels of quality of service (QoS). Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling may include determination of a type of datapath, including paging and synchronized datapaths. NAN data cluster base schedules may be scheduled as equal-sets or subsets of datapath schedules. The datapath model may be implemented for unicast and multicast communication between wireless stations.
