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.

Adapting blind reception duration for range and congestion

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.
