    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 a wireless station to transmit a paging beacon outside of a paging window may include establishing a paged data link with a peer station, determining that one or more data frames associated with the paged data link are pending transmission, and transmitting a beacon to the peer station outside of a scheduled paging window of the paged data link. The beacon may include a paging attribute indicating there are pending data frames.

    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 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.
