Abstract: In order to flexibly manage and broadcast content to electronic devices in a multicast group, a multicast group management protocol allows one or more multicast group masters to be specified. In addition to controlling membership in the multicast group, a multicast group master can define or specify a multicast session, in which content from one or more sources is broadcast to at least a subset of the electronic devices or sinks in the multicast group. The multicast group management protocol supports concurrent broadcasts of content to different multicast sessions. Moreover, the broadcasts in the different multicast sessions may have different: priorities, encoding techniques, quality-of-service policies, reliability, and/or number of parity bits. For example, the different encoding techniques may include different layers in H.264 Scalable Video Coding. Alternatively or additionally, the different number of parity bits may be associated with application layer forward error correction.

Abstract: The disclosed embodiments provide a system that enables service-configurable wireless connections. During operation, a local service endpoint of a service runs on a wireless device. The local service endpoint sends a request to establish a datapath with another service endpoint on another device. Meanwhile, the wireless device's service discovery module discovers a remote endpoint for the service on a remote device. In response to the request, the wireless device's service-configurable security entity configures a Wi-Fi connection's security configuration, thereby enabling the local endpoint to establish a datapath between the local endpoint and the remote endpoint over the Wi-Fi connection.

Abstract: An apparatus and methods are provided for coordinating multiple peer-to-peer (P2P) networks. A device operates a first P2P communications protocol to participate in a first P2P network. The device also operates a second P2P communications protocol to participate in a second P2P network. The device can modify at least one of the first P2P network's parameters and at least one of the second P2P network's parameters to minimize conflicts between operations of the P2P networks. To enable it to modify these parameters, the device may configure or reconfigure its operating parameters to cause it to take on a supervisory role (e.g., master, group owner).

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

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: Disclosed herein are system, method, and computer program product embodiments for performing multiuser block acknowledgement in a wireless communication protocol. Embodiments include receiving a control frame from an access point (AP). A transmission mode can be determined based on a trigger information field in the control frame. Further, a data frame to acknowledge can be determined based on a block acknowledgement request (BAR) field in the control frame. A block acknowledgment (BA) frame can be generated based on the data frame to acknowledge. The BA frame can then be transmitted to the AP based on the transmission mode, e.g., at the same time another BA frame is transmitted to the AP by another station.

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.
