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: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A wireless mobile station can determine an interval of time between successive target beacon transmission times. The wireless mobile station can adjust, based at least in part on the interval of time, a period of time of an awake timer in response to having determined the interval of time.

Abstract: An apparatus and methods are provided for opportunistically conducting data communications on multiple wireless channels. In these methods, a device is engaged in data communications with a second device and receives a conflicting communication demand requiring action on one or more channels other than the data-communication channel (e.g., to conduct a channel scan, to issue or receive a beacon). The device arranges a schedule of channel switches to satisfy the communication demand and advises the second device of the schedule, and may explicitly invite the second device to implement the schedule. To the extent the second device does so, the data communications continue on the other channels. The devices may be participating in a synchronized peer-to-peer communication environment that requires their attendance on the data-communication channel and that is not associated with the other channels.

Abstract: This disclosure relates to transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.

Abstract: 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. A wireless station may enter an unsynchronized discovery mode, transmit, in response to receiving a subscribe message from a neighboring device, a publish message to the neighboring device, perform authentication and trusted device cluster provisioning with the neighboring wireless device, and protect transmissions using the security credentials. In the unsynchronized discovery mode, the wireless device may monitor a discovery channel for subscribe messages, e.g., from neighboring peer devices. Additionally, the trusted device cluster provisioning may provide security credentials to the wireless device. Note that protecting transmissions using the security credentials may include protecting a trusted device cluster identity, transmitted beacons, transmitted management frames, or transmitted action frames using the security credentials acquired via the trusted device cluster provisioning.

Abstract: 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. A wireless station may determine a further availability window schedule for a first time period, including specifying availability for particular channels at particular time slots at a first time slot increment. The wireless station may specify availability at a second time slot increment for a subset of the time slots specified at the first time slot increment. The second time slot increment may be less than the first slot time increment. The wireless station may negotiate, with a neighboring wireless station, a peer-to-peer communication schedule for the peer-to-peer communication application based on the further availability window schedule, including specifying a portion of the peer-to-peer schedule using the second time slot increment.

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: 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. A wireless station may be configured to perform a method to accelerate discovery of a peer device after an out-of-band triggering event. For example, a wireless device may detect an out-of-band triggering event and activate a wireless interface capable of peer-to-peer communications in response. The wireless device may transmit one or more discovery messages (e.g., discovery beacons, active subscribe messages, and/or unsolicited publish messages) over the wireless interface immediately after activation of the wireless interface to aid in discovery of the peer device. The one or more discovery messages may be transmitted as service discovery frames. The wireless device may perform service discovery over the wireless interface with the peer device post discovery.

Abstract: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless 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. Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling attributes may include a native scheduler rank and a NAN data cluster scheduler rank. 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, including mobile stations.

Abstract: An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.
