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: 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 transmit, to a first peer wireless station, a first availability schedule that may include one or more types of committed availability and receive, from the first peer wireless station, a second availability schedule applicable to the wireless station but not other peer wireless stations. The types of committed availability may include a first type that is non-cancelable and a second type that is cancelable. The second availability schedule may be the second type. The wireless station may be further configured to transmit, to a second peer wireless station of the plurality of peer wireless stations, a third availability schedule where the third availability schedule may be the first type.

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 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 trigger, via a first interface, service discovery over a second interface. In some embodiments, the service discovery can involve the exchange of one or more Bloom filters.

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: In embodiments, a wireless device, such as a Wi-Fi device, transmits communication signals on secondary channels within an operational bandwidth of a wireless network, concurrent with a transmission from another wireless device on a primary channel. The wireless device may detect that a first frequency band within an operating bandwidth of a wireless network is occupied by a first transmission transmitted by a second wireless device, and determine that a second, different frequency band within the operating bandwidth of the wireless network is not occupied. In response, the wireless device may transmit a second transmission occupying the second frequency band concurrent with the first transmission. The wireless device may set a duration of the second transmission based at least in part on a determination of whether the second wireless device is configured to assess the state of all frequency bands within the operating bandwidth before beginning a subsequent transmission.

Abstract: In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client 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 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 client stations.

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.
