Abstract: PROBLEM TO BE SOLVED: To dissolve the complexity of inner/outer loop electric power control in using a fractional dedicated physical channel (F-DPCH).SOLUTION: Based on a signal strength or quality of a standard channel signal, and an estimate value of a gain factor about a control channel signal and the standard channel signal, an electric power control feedback of the control channel signal received together with the standard channel signal is generated. As a non-restrictive example shown in a context of extensive belt CDMA (WCDMA (R)), the standard channel signal includes a common pilot channel (CPICH) signal, and the control channel signal includes an F-DPCH signal to be transmitted by an electric power gain (unknown) to the CPICH signal.
