    Abstract: Methods and apparatus for dynamic, adaptive scanning of communication channels are provided. A device alternates between scan cycles and rest cycles. A scan cycle includes interleaved intervals of scanning and resting. A scan interval may involve active or passive scanning, and a rest interval may be active or inactive. An active rest interval is spent tending to a communication requirement other than scanning (e.g., an infrastructure connection, a peer-to-peer connection). An inactive rest interval may be spent in a low-power mode of operation. Rest cycles, like rest intervals, may also be active or inactive. Durations of rest cycles and rest intervals increase each time a scan cycle completes without detection of any significant event or signal (e.g., until they reach a maximum). Upon detection of a significant event, they decrease, possibly by being reset to default durations.

    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 some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless 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. Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling attributes may include a native scheduler rank and a NAN data cluster scheduler rank. 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, including mobile stations.

    Abstract: One or more wireless stations may operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A mechanism for a wireless station to transmit a paging beacon outside of a paging window may include establishing a paged data link with a peer station, determining that one or more data frames associated with the paged data link are pending transmission, and transmitting a beacon to the peer station outside of a scheduled paging window of the paged data link. The beacon may include a paging attribute indicating there are pending data frames.

    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 a mechanism for a wireless station to discover a neighboring peer wireless station, e.g., via peer-to-peer Wi-Fi communications, receive a synchronization beacon(s) from the neighboring peer wireless station, and synchronize timing with the neighboring peer wireless station based at least in part on the synchronization beacon(s). In addition, the wireless station may transmit, e.g., via Wi-Fi peer-to-peer communications, a data beacon to one or more neighboring wireless devices stations, wherein the one or more neighboring wireless stations are configured to synchronize timing with the wireless station based on the data beacon.
