Abstract: A method and apparatus are disclosed that allow a first wireless device to form a peer-to-peer (P2P) connection with a second wireless device that does not operate on the social channels of a first frequency band. The first wireless device receives, from the second wireless device, an action frame indicating a selected channel in a second frequency band. The first wireless device may scan a number of social channels in the first frequency band to discover a presence of another wireless device, and then scans the selected channel to discover the presence of the second wireless device.

Abstract: A method of operating a user station (STA) to scan for access points (APs). The STA broadcasts a probe request on a first saved channel of one or more saved channels. More specifically, each of the one or more saved channels corresponds to a channel on which the STA had prior communications with an AP. The STA remains on the first saved channel for an extended duration to listen for a probe response from a first AP. Specifically, the extended duration is greater than a dwell time of the STA when scanning wireless channels other than the one or more saved channels.

Abstract translation: 一种操作用户站（STA）以扫描接入点（AP）的方法。 STA在一个或多个保存的频道的第一个保存的频道上广播探测请求。 更具体地，一个或多个保存的信道中的每一个对应于STA先前与AP通信的信道。 STA保持在第一个保存的信道上持续一段时间，以监听来自第一AP的探测响应。 具体地说，扩展持续时间大于STA扫描除一个或多个保存的通道之外的无线信道时的停留时间。

Abstract: A wireless device implements power saving logic for two or more wireless clients that concurrently communicate on a shared wireless channel (single channel concurrency). When one of the wireless clients transitions from power save mode to active mode (e.g., in response to a beacon signal), the power saving logic causes the other wireless client(s) to transition to active mode as well. Each wireless client ‘awakened’ in this manner transmits a NULL frame having a power management bit set to a logic ‘0’ value to an associated access point (AP), thereby indicating its active status to the associated AP. As a result, all of the wireless clients may concurrently receive buffered data from their associated APs on the shared wireless channel. If the ‘awakened’ wireless client(s) do not need to transition to active mode in response to their next received beacons, power consumption of the wireless device is advantageously reduced.

Abstract translation: 无线设备为在共享无线信道（单信道并发）上同时通信的两个或更多个无线客户端实现功率节省逻辑。 当其中一个无线客户端从省电模式转换到活动模式（例如，响应于信标信号）时，功率节省逻辑也使另一无线客户端转换到活动模式。 以这种方式“唤醒”的每个无线客户端将具有设置为逻辑“0”值的功率管理位的空帧发送到相关联的接入点（AP），从而向相关联的AP指示其活动状态。 结果，所有无线客户端可以并发地从共享无线信道上的相关AP接收缓冲数据。 如果“唤醒”的无线客户端不需要响应于其下一个接收的信标转换到主动模式，则有利地减少了无线设备的功率消耗。
