A power control system for a cellular mobile telephone system in which system users communicate information sig- nals between one another via at least one cell-site using code division multiple access spread spectrum communication sig- nals. The power control system controls transmission signal power for each cellular mobile telephone (16, 18) in the cellu- lar mobile telephone system wherein each cellular mobile telephone (16, 18) has an antenna, transmitter and receiver and each cell-site (12, 14) 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 in- creases and decreases in received signal power. A power con- trol feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit trans- mitted power is measured as received at the cell-site. A com- mand 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 corresponding to devia- tions 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. In a cell diversity situation, the mobile units transmitter power is adjusted to prevent un- necessary increases in mobile unit transmitter power level.
