A method for controlling a reference SIR used for a closed loop control in a CDMA mobile communications system is disclosed. When an uplink channel has insufficient communication quality, the reference SIR is increased by a predetermined increase amount. When the uplink channel has sufficient communication quality, it is determined whether the base station is involved in the closed loop control. When the base station in involved in the closed loop control, the reference SIR in decreased by a predetermined first decrease amount. When the bane station is not involved in the closed loop control, the reference SIR is decreased by e predetermined second decrease amount which is greater than the predetermined first decrease amount.
