Abstract
A method and apparatus for controlling transmission power in a variable rate communication system is disclosed. The method disclosed provides for a closed loop power control method. A first remote station controls the transmission power of a second remote station by transmitting a rate dependent power control signal to the second remote communication station. Since only the second communication knows its transmission rate a priori, it must determine its course of action in accordance with both the received power control signal and the knowledge of its transmission rate. In the present invention, the power control system reduces the amount of overhead required by restricting the possible rate transition of the variable rate communication system. The power control system further increases its efficiency by allocating the power control bits top various rate hypotheses in accordance with the probability of the rate hypothesis and the perceptual impact of power control for frames of data transmitted at the hypothetical rate.
