Abstract  Abstract

The invention relates to a mobile station for use in a
cellular-communications network using spread-spectrum
modulation wherein a base station transmits spread-spectrum
signals which are received by the mobile station and the
mobile station includes a transmitter (112) and an associated
antenna for transmitting spread-spectrum signals to the base
station. The mobile station includes an adaptive-power
control comprising:
at least one circuit (101, 102, 103; 201, 202, 203) for
acquiring and decoding said spread-spectrum signals from said
base station; a detector (104) coupled to one of said
acquisition circuits (101, 102, 103) for detecting a received
power level of a generic spread-spectrum signal transmitted
by the base station; a decoder (105) coupled to one of said
acquisition circuits (101, 102, 103; 201, 202, 203) for
decoding a threshold value of an APC-data signal encoded
within a spread-spectrum signal transmitted by the base
station; a differential amplifier (106) coupled to said
detector (104) and said decoder (105) for generating a
comparison signal by comparing the received power level to
said threshold value; and a variable-gain device (111)
coupled to said differential amplifier (106) and between the
mobile stations transmitter (112) and antenna, responsive to
said comparison signal indicating an increase or decrease,
for adjusting a transmitter-power level of the transmitter
spread-spectrum signal from said mobile station transmitter
(112).
