摘要： A system, apparatus and method for selecting one or more synchronization stations, or masters, in a peer-to-peer communication environment. Synchronization (or sync) stations broadcast periodic synchronization frames to advertise future availability windows, during which devices rendezvous for discovery and communication. Devices that can act as sync stations advertise preference values, which indicate their preference or suitability for the role. All devices execute the same algorithm to sort the preference values and identify a root sync station and any number of branch sync stations; leaf devices synchronize with the root or a branch sync station. This passive synchronization scheme allows individual devices to conserve power, because they need not actively discover other devices and services, and can power off their radios for periods of time without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexist with other device demands, such as Bluetooth® operations and infrastructure-based communications.
摘要翻译：一种用于在对等通信环境中选择一个或多个同步站或主站的系统，装置和方法。同步（或同步）站广播周期性同步帧以通告未来可用性窗口，在此期间，设备会合用于发现和通信。可以充当同步站的设备会发布偏好值，这表明它们对该角色的偏好或适用性。所有设备执行相同的算法对优先级值进行排序，并识别根同步站和任意数量的分支同步站; 叶设备与根或分支同步站同步。这种无源同步方案允许单个设备节省电力，因为它们不需要主动发现其他设备和服务，并且可以在不牺牲可发现性的情况下关闭其无线电一段时间。如本文提供的同步和对等通信与其他设备需求（如蓝牙®操作和基于基础设施的通信）共存。

摘要： A method for scheduling absence periods on a WLAN is provided. The method can include a WLAN station joining a WLAN served by a WLAN access point using an operating channel; formatting a message defining an absence schedule of absence periods during which the WLAN station will be off of the operating channel and unavailable to receive traffic on the operating channel; sending the message to the WLAN access point to register the absence schedule with the WLAN access point; and leaving and returning to the operating channel in accordance with the absence schedule after the absence schedule has been registered with the WLAN access point.
摘要翻译：提供了一种在WLAN上调度不存在时段的方法。该方法可以包括使用操作信道加入由WLAN接入点服务的WLAN的WLAN站; 格式化消息，定义无线时段的不在时间表，在该时间段期间，WLAN站将离开操作信道，并且不能在操作信道上接收业务; 将消息发送到WLAN接入点，以向WLAN接入点注册不存在的时间表; 并且在无线接入点已经注册了缺席日程表之后，根据不在时间表离开并返回到操作信道。
