A system and method for adaptive-power control of a spread-spectrum transmitter of a mobile station operating in a cellular-communications network using spread-spectrum modulation. A mobile station transmits a first spread-spectrum signal. A base station has an automatic-gain-control circuit for generating an AGC-output signal, from a received signal. The received signal includes the first spread-spectrum signal and an interfering signal. The base station also has a correlator for despreading the AGC-output signal, a power-measurement circuit responsive to processing the received signal with the despread AGC-output signal for generating a received-power level, a comparator coupled to the power-measurement circuit for generating a comparison signal by comparing the received-power level to a threshold level, a transmitter for transmitting a second spread-spectrum signal, and an antenna. The mobile station has a variable-gain device responsive to the comparison signal for adjusting a transmitter-power level of the first spread-spectrum signal.

[ What is claimed is:] [11.]11. A method for adaptive-power control in a cellular-communications network using spread-spectrum modulation wherein a communication station receives signals including a specific spread-spectrum signal transmitted by a second communication station at an adjustable transmit power level, said method comprising the steps of:receiving signals including said specific spread-spectrum signal by the communication station;normalizing a power level associated with said received signals;despreading said normalized received signals with a unique code to acquire a despread signal corresponding to the specific spread-spectrum signal;narrow band filtering said despread signal;multiplying said received signals with said filtered despread signal and measuring a power level associated with a resultant multiplied signal to obtain a received power level associated with the specific spread-spectrum signal;generating a power command signal by comparing said received power level with a threshold level;transmitting said power command signal to the second station; andadjusting the second station transmit power level with said power command signal.
