A method and apparatus for controlling transmission power in a mobile communication system is disclosed. The method disclosed provides for a closed-loop power control method for variable rate transmissions. The power of transmissions is varied in accordance with the rate of the frames of data being transmitted. The transmission power between the rates can be a fixed or variable difference.

1. A method for controlling transmission power of variable rate frames of data, comprising:receiving a frame quality message from a remote communication station;receiving a gain adjustment value and a previous reference rate transmit value, and summing said gain adjustment value and said previous reference rate transmit value to provide a reference rate transmit power level;determining at least one additional transmit power level in accordance with said reference rate transmit power level and providing a transmit power signal based at least in part on said one additional transmit power level; andamplifying said variable rate frames in accordance with said transmit power signal and a rate of said variable rate frames of data.2. The method of claim 1 further comprising:receiving said reference rate transmit power level and a fixed difference value; andsumming said reference rate transmit power level and said fixed difference value to determine said at least one additional transmit power level.3. The method of claim 1 further comprising:receiving said reference rate transmit power level and a variable difference value; andsumming said reference rate transmit power level and said variable difference value to determine said at least one additional transmit power level.4. The method of claim 3 further composing:determining at least one frame error rate value; andusing said at least one frame error rate value to determine said variable difference value.5. The method of claim 4 further comprising:receiving said frame quality message and outputting said frame quality message upon a selected output in accordance with a frame quality message rate; andcounting said frame quality message rate upon the selected output.6. An apparatus for controlling transmission power of variable rate frames of data comprising:means for receiving a frame quality message from a remote communication station;means for receiving a gain adjustment value and a previous reference rate transmit value, and summing said gain adjustment value and said previous reference rate transmit value to provide a reference rate transmit power level;means for determining at least one additional transmit power level in accordance with said reference rate transmit power level and providing a transmit power signal based at least in part on said one additional transmit power level; andmeans for amplifying said variable rate frames in accordance with said transmit power signal and a rate of said variable rate frames of data.7. The apparatus of claim 6 further comprising;means for receiving said reference rate transmit power level and a fixed difference value; andmeans for summing said reference rate transmit power level and said fixed difference value to determine said at least one additional transmit power level.8. The apparatus of claim 6 further comprising:means for receiving said reference rate transmit power level and a variable difference value; andmeans for summing said reference rate transmit power level and said variable difference value to determine said at least one additional transmit power level.9. The apparatus of claim 8 further comprising:means for determine at least one frame error rate value; andmeans for using said at least one frame error rate value to determine said variable difference value.10. The apparatus of claim 9 further comprising:means for receiving said frame quality message and outputting said frame quality message upon a selected output in accordance with a frame quality message rate; andmeans for counting said frame quality message rate upon the selected output.
