    Abstract: An electronic device (such as an access point) may provide a management frame, intended for at least a recipient electronic device, that includes slotted-operation information corresponding to a power-save mode of the electronic device for communication with at least the recipient electronic device. The slotted-operation information may include a sequence of temporal slots and associated channel information for the temporal slots. When a channel for a temporal slot comprises a null value, the power-save mode may include transitioning the electronic device into a lower-power-consumption mode during the temporal slot. Alternatively, when a channel for a temporal slot is different than a null value, the power-save mode may include performing another activity than communicating with the recipient electronic device during the temporal slot.

    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 wireless stations to learn preferred channels of neighboring wireless stations and to schedule channel sequences within a time period based on the learned channels may include advertisement of preferred channels and adaptation of channel sequences, based on the preferred channels, to maximize bandwidth utilization.

    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 accelerated service discovery between peer devices. In some embodiments, a wireless device may broadcast a probe beacon on one or more discovery channels. The wireless device may then scan the discovery channels for an extended period of time. The wireless device may receive a response from a peer device and transmit further service information to the peer device in an availability window indicated in the response.

    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 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 peer devices to transmit availability schedules beyond 512 time units while continuing to minimize communication overhead. In some embodiments, a wireless station may discover a peer wireless station and transmit extended availability information. In some embodiments, the extended availability information may indicate one or more of an availability interval duration, a bitmap length, and/or a repeat interval of the availability information. In some embodiments, the extended availability information may indicate a maximum number of receivable spatial streams and/or a channel bandwidth. In some embodiments, the extended availability information may include or indicate availability of the wireless station for more than 512 time units.

    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.
