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: 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 mitigate medium congestion in discovery windows may include suppressing solicited publisher responses via an SRF for a first time period and resetting the SRF after the first time period in order to receive updates from peer devices.

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 some embodiments, one or more wireless stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., without utilizing an intermediate access point. Embodiments relate to scheduling of NAN ranging procedures, including to a first wireless station sending first information, including first scheduling preferences and a first ranging role, to a second wireless station. The first wireless device receives second information, including second scheduling preferences and a second ranging role, from the second wireless device. 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 that communicates with a second electronic device is described. During operation, an electronic device communicates first messages with the second electronic device in time slots corresponding to first channels in a first band of frequencies using a peer-to-peer communication protocol (such as neighbor awareness networking or NaN), where, in a given time slot, a given first channel in the first band of frequencies is used in the communication of the first messages. Moreover, the electronic device communicates second messages with the second electronic device in the time slots corresponding to second channels in a second band of frequencies using the peer-to-peer communication protocol, where, in the given time slot, a given second channel in the second band of frequencies is used in the communication of the second messages. Note that the communicating of the first messages and the second messages may at least partially overlap in time.

Abstract: Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.
