Abstract
A forward power controlling apparatus in a CDMA mobile communication system is provided. In the forward power controlling apparatus, an SIR measurer measures the SIR of each received frame on a forward user channel using all the demodulated symbols of the frame, a symbol rate detector detects symbol rate information inserted in a predetermined position of the frame, and a controller changes a threshold according to the detected symbol rate information, compares the threshold with the SIR, and generates a forward power control command.
