    Abstract: A system, apparatus, and method are provided for operating a peer-to-peer communication environment. The environment includes one or more clusters of peer devices, wherein devices in a single cluster are organized into a logical hierarchy under an anchor master (at the root of the hierarchy) and any number of synchronization masters; other devices are non-master devices. Synchronization parameters established by the anchor master and disseminated throughout the hierarchy enable the clusters' devices to rendezvous, discover peers and services, and communicate among themselves. The anchor master may adjust the synchronization parameters to avoid conflict with another hierarchy. Each device issues beacons (e.g., heartbeats, discovery beacons) that identify the number of devices synchronized with the reporting device, which allows the anchor master to calculate the total number of cluster members. Devices may also report details of a neighboring cluster (e.g., its synchronization parameters) via a beacon or some other communication.

    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 NAN devices to assist one another in receiving communications from an access point common to the peer NAN devices. In some embodiments, a wireless station may establish a communication link with a Wi-Fi access point and establish a peer-to-peer communication link with one or more neighboring wireless stations. In addition, the wireless station may receive transmissions intended for at least one neighboring wireless station of the one or more neighboring wireless stations from the Wi-Fi access point and relay the transmissions to the at least one wireless station on behalf of the Wi-Fi access point.

    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 translation: 提供了通信信道的动态，自适应扫描的方法和装置。 一个设备在扫描周期和休息周期之间交替。 扫描周期包括扫描和休息的交错间隔。 扫描间隔可以涉及主动或被动扫描，并且休息间隔可以是活动的或不活动的。 除了扫描（例如，基础设施连接，对等连接）之外，主动休息间隔用于趋向于通信要求。 不活动的休息间隔可以用在低功率操作模式中。 休息周期，如休止间隔，也可能是活动或非活动。 每次扫描周期完成，休息周期和休息间隔的持续时间都会增加，而不会检测到任何重大事件或信号（例如，直到达到最大值）。 在检测到重大事件时，它们可能会被重置为默认持续时间。

    Abstract: A system, apparatus and method for selecting master devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master as part of periodic synchronization frames. Devices capable of serving as master advertise their selection metrics, which are converted into a master preference value by a selection algorithm applied uniformly by all devices in the environment. Individual devices may identify the best local master and synchronize to it, yielding a cluster of synchronized peers. Clusters may then be synchronized to masters at further range. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on.

    Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.
