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.

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: An apparatus comprises a memory and at least one processor in communication with the memory. The at least one processor is to detect, during a discovery window, a neighboring client station that is to perform peer-to-peer Wi-Fi communication via a Neighbor Awareness Networking (NAN) protocol and establish, via a negotiation after the discovery window, a datapath with the neighboring client station, wherein the negotiation includes an exchange of NAN data path setup attributes in parallel with an exchange of encryption cipher attributes and the encryption cipher is based on a simultaneous authentication of equals (SAE) protocol. The SAE protocol can be used to generate key material to encrypt the datapath.

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: One or more wireless stations may operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., without utilizing an intermediate access point. Scheduling of NAN ranging procedures may include a first wireless station sending first information, including first scheduling preferences and a first ranging role, to a second wireless station. The first wireless station receives second information, including second scheduling preferences and a second ranging role, from the second wireless station. The first wireless station may initiate the ranging procedure based on the scheduling preferences and ranging parameters. Alternatively, the second wireless station and may initiate the ranging procedure based on the scheduling preferences and ranging parameters.

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.
