    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 device to perform multicast communications amongst a group of peer devices. Embodiments described herein provide mechanisms for initiation (or establishment) and scheduling of a multicast group as well as enrollment of a device into a multicast group, merging of multicast groups, and termination of multicast groups.

    Abstract: Embodiments relate to wireless stations that operate to configure direct communication between the wireless stations without utilizing an intermediate access point. In embodiments, a wireless station may establish a peer-to-peer communication schedule with at least one neighboring peer wireless station, announce, to the at least one neighboring peer wireless station, a schedule transition (or migration), wherein the schedule transition includes an effective time of a new schedule, and announce, to the at least one neighboring peer wireless station, the new schedule at the effective time.

    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.

    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.

    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: A system, apparatus and method for synchronizing devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master. Devices may attend some or all of the availability windows, during which they may send and receive unicast and/or multicast messages. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on.
