ADAPTING BLIND RECEPTION DURATION FOR RANGE AND CONGESTION

摘要

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.

1. A method of wireless communication, comprising:
measuring a channel condition parameter for a wireless channel; adjusting a sleep timer based at least in part on the channel condition parameter, wherein the sleep timer is associated with a receive window of an expected wireless transmission; and entering a sleep state based at least in part on the adjusted sleep timer and an absence of the expected wireless transmission during the receive window.
