PURPOSE: A method for controlling power of an uplink external circuit in a wireless communication system is provided to compare quality of an originating signal of a mobile station with quality desired by a system, and to increase or decrease a target SIR(Signal-to-Interference Ratio) value of the system used for high-speed power control, thereby controlling power of the uplink external circuit. CONSTITUTION: A wireless communication system reads a QE(Quality Estimate) value of a receiving signal(401). If the receiving signal has an error, the system increases a target SIR value as much as amount proportional to the QE value(403,409). If the receiving signal does not have the error, the system decreases the target SIR value as much as predetermined amount(405,407). The system stores the increased/decreased target SIR value, compares the increased/decreased target SIR value with a previous target SIR value, and sets the increased/decreased target SIR value to a target SIR value if a change of the target SIR value exceeds an optional SIR change(411,413).
