Abstract: A method for determining a threshold value for controlling output power of a mobile communication terminal in a W-CDMA system, includes: calculating a first value by dividing an average energy per a PN chip of downlink DPCCH by a total received power spectral density of downlink; calculating a second value by dividing the total received power spectral density of downlink by a white noise power spectral density; calculating a chip unit SIR by adding the first and second values; and determining a symbol unit threshold value for controlling ON/OFF of terminal output power by adding the chip unit SIR and a processing gain according to the number of chips per symbol. Accordingly, a symbol unit threshold value for controlling output power can be easily determined irrespective of a value of a data rate and a spreading factor.

Abstract: A method is provided for controlling power of radio links, particularly a method for controlling transmit power of a terminal in soft handover. This may include a process for setting transmit power control commands from each radio link according to quality of each radio link, and a process for setting a combined transmit power control command by confirming whether the transmit power control commands from each radio link are identical for all the radio links. The method for controlling power of the radio links may prevent reduction of reliability of the transmit power control commands in the process for deciding the transmit power control commands from different radio link sets to control the transmit power of the terminal in soft handover.
