摘要： A system for dynamic adaptation of wireless communication between a Mobile Station (11) and a Base Station (13) wherein the transmitted frame from the Mobile Station includes a convolutionally coded portion containing a down-link measurement bit and a repetition code identifying the codec mode of the frame. The transmitted frame from the Base Station (13) includes a codec mode command signal for the Mobile Station (11) in the convolutionally encoded portion and the repetition code identify the codec mode of the down-link frame. The Base Station (13) includes means for analyzing the quality of the up-link frame and means from the received down-link measurement bit for determining the down-link quality.
