Abstract

A method, apparatus and radio network controller for outer loop power control processing are provided by the embodiments of the present invention. The method includes the following steps: if the transmission power of a terminal is limited, the maximum target value A of Dedicated Physical Control Channel (DPCCH) Signal Interference Ratio (SIR) is adjusted to B, wherein B is greater or equals to the initial target value of DPCCH SIR and is less than A; and the adjusted maximum target value of DPCCH SIR is transmitted to a base station. In the embodiments of the present invention, the maximum target value of DPCCH SIR is reduced to the initial target value of DPCCH SIR when the transmission power of a terminal is limited, and thus the dynamic range of the DPCCH SIR is reduced, so that the power proportion of the control channel is reduced, thereby the power proportion of the data channel is increased, the data transmission can be continued and the cell coverage is increased.
