    Abstract: A method for providing power control with variable data rate, the method comprising: receiving a data frame having an input data rate selected from a plurality of possible input data rates; selecting an encoding rate based on the input data rate; encoding data frames to produce output symbols, repeating output symbols using first and second generating polynomials and multiplexing the repeated output symbols, selecting a puncturing format to puncture data bits and producing output data having a constant output data rate for a number of possible input data rates based on a combination of input data rates, selected encoding rate and selected puncturing format for providing said variable data rate communication link; determining a frame error rate for a number of possible input data rates; calculating differences between the frame error rates and a target error rate and adjusting the power depending on whether the difference is greater, equal or less than a predetermined threshold.

    Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.
