Abstract: Methods, systems, and devices are described for adapting blind reception duration for range and congestion. A wireless station may measure channel conditions (e.g., range to an access point (AP) and channel congestion), and adjust one or more sleep timers based on the conditions. The sleep timers may each be associated with a window for reception of an expected transmission. If the transmission is not received in the window, the station may enter a sleep state to conserve power. In one example, a beacon miss timer is adjusted, and the expected wireless transmission is a delivery traffic indication message (DTIM). In another example, a content after beacon (CAB) timer is adjusted and the expected wireless transmission is the CAB. In some cases, the station may measure a delay for a number of beacons and determine the adjustment based on the delays.

Abstract: A wireless communication device having a root complex, a WLAN module, a power module and an interface linking the root complex and the WLAN module, wherein the root complex is configured to implement a power management policy based upon a latency tolerance value for the WLAN module and wherein the power module is configured to adjust the latency tolerance value based upon receive and transmit parameters of the WLAN module. The power module may be configured to adjust the latency tolerance value on a per-frame basis.

Abstract translation: 描述了用于适应范围和拥塞的盲接收持续时间的方法，系统和设备。 无线站可以测量信道条件（例如，到接入点（AP）的范围和信道拥塞），并且基于条件来调整一个或多个睡眠定时器。 睡眠定时器可以各自与用于接收预期传输的窗口相关联。 如果窗口中没有接收到传输，则站可能进入睡眠状态以节省电力。 在一个示例中，调整信标缺失定时器，并且期望的无线传输是传送业务指示消息（DTIM）。 在另一示例中，调整了信标（CAB）定时器之后的内容，并且预期的无线传输是CAB。 在某些情况下，车站可以测量多个信标的延迟，并根据延迟确定调整。
