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.

[ We claim:] [1.] In a variable rate communication system wherein a first communication device for the transmission of a data packet of variable rate data in a data frame of a predetermined data capacity to a second communication device wherein when said data packet is less than said data capacity generating repeated versions of bits in said data packet and providing first version of said data packet bits and said repeated versions of said data packet bits in said data frame and wherein in the transmission power for transmitting said data frame is scaled in accordance with the data rate of said variable rate data, an apparatus for controlling said transmission power of said first communication device at said second communication device comprising:receiver means for receiving said data frame;frame quality determination means for determining a frame quality factor from said data frame;comparison means for comparing said frame quality factor against a plurality of threshold values to provide a quality signal in accordance with said data rate and wherein each of said threshold values corresponds to a different data rate; andtransmitter means for transmitting said quality signal.
