Systems, methods, and devices for saving power in wireless communications devices are described herein. In some aspects, an apparatus includes a memory unit configured to store wake-up information associated with a wake-up time duration for receiving a beacon signal, and includes a processor operationally coupled to the memory unit. The wake-up time duration identifies a time for the processor to wake-up before an expected arrival time of the next beacon signal. The processor may be configured to retrieve the wake-up information from the memory, and vary, over a period of time, the wake-up time duration based on the wake-up information. |

1. An apparatus for wireless communication, comprising:
a memory unit configured to store wake-up information associated with a wake up time duration for receiving a beacon signal; a missed beacon counter configured for incrementing based on a result of a channel adversity condition; and a processor operationally coupled to the memory unit and the missed beacon counter, the processor configured to: retrieve the wake-up information from the memory, vary, over a period of time, the wake-up time duration based on the wake-up information and the channel adversity condition, wherein the wake-up time duration identifies a time for the processor to wake-up before an expected arrival time of the next beacon signal and a time period to remain awake, determining, by the processor, a missed beacon signal, wherein the missed beacon counter increments when the missed beacon signal is not the result of the channel adversity condition, wherein the missed beacon counter does not increment when the missed beacon signal is the result of the channel adversity condition, determining, by the processor, a beacon miss rate based on a value of the missed beacon counter, increasing, by the processor, the time for the processor to wake-up before an expected arrival time of the next beacon signal when the beacon miss rate is greater than a target beacon miss rate, and waking-up, by the processor, based on the increase in the time for the processor to wake-up before an expected arrival time of the next beacon signal. |
