Abstract: An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface 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: 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.

Abstract: This disclosure relates to service discovery using a dynamically configurable Bloom filter. According to some embodiments, various parameters of the Bloom filter may be determined by a first wireless device. The parameters may include a number of services advertised using the Bloom filter, a false positive rate of the Bloom filter, a set of hash functions used with the Bloom filter, and/or a size of the Bloom filter. The Bloom filter may be generated according to the determined parameters. The Bloom filter, along with some or all of the parameters of the Bloom filter, may be transmitted by the first wireless device. A second wireless device may use the Bloom filter as part of a service discovery process to determine whether or not a desired service is available via the first wireless device.

Abstract: An apparatus and methods are provided for initiating a network connection between a first device and a second device. While one or more high-power network interfaces of the first device are in a dormant state, the first device communicates with a second device via the first device's low-power network interface. The first device can determine, based on the communication, whether to establish a network connection with the second device via a high-power network interface of the first device. Next, if the first device is to establish the network connection with the second device via the high-power network interface, the device can wake the first high-power network interface and connect to the second device via the first high-power network interface.

Abstract: Methods and apparatus for dynamic, adaptive scanning of communication channels are provided. A device alternates between scan cycles and rest cycles. A scan cycle includes interleaved intervals of scanning and resting. A scan interval may involve active or passive scanning, and a rest interval may be active or inactive. An active rest interval is spent tending to a communication requirement other than scanning (e.g., an infrastructure connection, a peer-to-peer connection). An inactive rest interval may be spent in a low-power mode of operation. Rest cycles, like rest intervals, may also be active or inactive. Durations of rest cycles and rest intervals increase each time a scan cycle completes without detection of any significant event or signal (e.g., until they reach a maximum). Upon detection of a significant event, they decrease, possibly by being reset to default durations.

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).
