Abstract
A method and apparatus for effectively monitoring quality of a traffic channel in a communication, and in response, modifying transmission coding or data transmission rates, or both, improves communication quality and increases data transfers rates in digital wireless communication systems. A channel quality estimator determines and evaluates the bit error rate (BER) of a signal on a control channel and estimates the quality of the traffic channel based on the quality of the control channel signal. Accordingly, the processing and control circuitry of either a mobile station or base station adjusts the error correction applied to traffic channel transmissions. The traffic channel data transmission rate may also be modified based on the control channel signal quality.
