Abstract

A method in a receiver includes receiving from a transmitter an instruction to check for messages from the transmitter at intervals having a specified time period. A frequency error of the receiver relative to the transmitter is estimated at the receiver, and an actual time period that does not exceed the specified time period is selected based on the estimated frequency error. The receiver is activated periodically according to the selected actual time period so as to reset the frequency error.
