Abstract:
1. A method for conserving power consumed by wireless communication hardware, the method comprising the steps of: receiving scheduling related information with a packet for transmission, wherein the scheduling related information can be used to determine an expected response time for receiving an expected response related to the packet for transmission; transmitting the packet for transmission using the wireless communication hardware; scheduling an awake state of the wireless communication hardware based on the expected response time if the transmitting was successful, wherein scheduling the awake state comprises: determining a timer value; determining a timer index if the timer value does not exceed a timer array, wherein the timer index is based on a current timer index and the timer value divided by a granularity of the timer array; adjusting the timer index if the timer index is greater than a largest index of the timer array; entering the scheduling information into the timer array at the timer index; and placing the wireless communication hardware into a doze state unless the wireless communication hardware is transmitting data, or is otherwise scheduled to be in the awake state.
