An apparatus and method for adaptive-power control of a spread-spectrum transmitter of a mobile sta- tion operating in a cellular- communications network us- ing spread-spectrum modula- tion. A base station transmits a first spread-spectrum sig- nal. A mobile station has an automatic-gain-control cir- cuit (72) for generating an AGC-output signal, from a received signal. The received signal includes the first spread-spectrum signal and an interfering signal. The mo- bile station also has a correla- tor (74) for despreading the AGC-output signal, a power- measurement circuit respon- sive to processing the re- ceived signal with the des- pread AGC-output signal for generating a received-power level, a comparator (70) coupled to the power-measurement circuit for generating a comparison signal by comparing the received-power level to a threshold level, a transmitter (58) for transmitting a second spread-spectrum signal, an antenna (56), and a variable-gain device (77) responsive to the comparison signal for adjusting a transmitter-power level of the second spread-spectrum signal.
