Abstract
A transmission power control method in a mobile communication system using a code division multiple access (CDMA) method includes: a power control process in an access mode having: a step of measuring a transmission power of an initial access channel transmitted from a terminal; a step of comparing the measured transmission power level with a pre-setted adequate power level; a step of transmitting a transmission power adjusting message to the terminal according to the comparison result; and a step of the terminal adjusting the transmitting power of the traffic channel to the adequate power level according to the transmission power adjusting message transmitted from a base station; and a power control process in a traffic mode having: a step of measuring the transmission power level of the traffic channel transmitted from the terminal; a step of comparing the measured transmission power level with the pre-setted adequate power level; a step of transmitting an one-bit power control bit to the terminal according to the comparison result; and a step of the terminal increasing/decreasing the transmitting power of the traffic channel by 1 dB according to the power control bit transmitted from the base station.
