Title: WIRELESS COMMUNICATION DEVICE POWER REDUCTION METHOD AND APPARATUS
Abstract:
A wireless communications power saving method and apparatus is provided. The method includes, when no reverse link traffic exists and no forward link traffic has been received for a predetermined amount of time, establishing, at a terminal, a reverse link transmission pilot signal duty cycle, and boosting overhead channel signal transmission power during ON slots and gating overhead channel and pilot signal transmission power during OFF slots. The design further includes estimating, at the terminal, an available data transmission rate, determining an actual data transmission rate, setting a terminal transmission duty cycle for a next period based on the estimated available data transmission rate, the actual data transmission rate, and a margin of error, and transmitting data from the terminal according to the terminal transmission duty cycle.
