<p>A method is provided for controlling a traffic-to-pilot ratio (TPR) in a wireless telecommunications channel. The methodology takes advantage of a preexisting feedback process used in hybrid ARQ transmission systems. Generally, information is transmitted over the communications channel, and then the acknowledgement (ACK) signal, or negative acknowledgements (NACK) signal, is used to adjust the TPR. The TPR is adjusted up substantially in response to receiving a NACK signal, and adjusted slightly down in response to receiving an ACK signal. In this manner, the TPR is rapidly adjusted up when a transmission fails, and is allowed to drift slowly down when a transmission succeeds.</p> |
