Wireless communication device power reduction method and apparatus

摘要

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.

1. A method for saving power in a wireless communication terminal, the method comprising:
estimating, at the terminal, an available data transmission rate for transmission from an access node to the terminal; determining, at the terminal, an actual data transmission rate for transmission from the access node to the terminal; setting a terminal transmission duty cycle for a next period, wherein the terminal transmission duty cycle is calculated using the estimated available data transmission rate, the actual data transmission rate, and a margin of error; and transmitting data from the terminal to the access node according to the terminal transmission duty cycle.
