Abstract  Abstract

An apparatus for adaptive-power control of a spread-spectrum transmitter of a mobile station operating in a cellular-com-munications network using spread-spectrum modulation. A base station transmits a generic spread-spectrum signal and an APCinformation-data signal. A mobile station has an acquisition circuit (101, 102, 103) for acquiring and decoding the generic spread-spectrum signal, a detector (104) for detecting a received power level of the generic spread-spectrum signal, a decoder (105) for decoding the APC-data signal as a threshold, a differential amplifier (106) for generating a comparison signal by comparing the received power level to the threshold, a transmitter (112) for transmitting a transmitter spread-spectrum signal, an antenna, and a variable-gain device (111) responsive to the comparison signal indicating an increase or decrease for adjusting a transmitter-power level of the transmitter spread-spectrum signal.
