CELLULAR COMMUNICATIONS POWER CONTROL SYSTEM

摘要

Two-way adaptive power control and signal quality monitoring and power control responsive thereto are provided for controlling the power output levels of transmitters (210) to the minimum necessary for satisfactory communications. Each transmission includes a code representative of the transmitter output power level. Receivers (212) compare this code to the received signal strength and ajust their associated transmitter power output level accordingly. Bit error rate (218) and SNR (223) are monitored by receivers to develop a measure of signal quality (220). A signal quality code is transmitted (250) to remote units and transmission output power level is adjusted in response.
