Transceiver apparatus and method for continuous outer loop power control in dtx mode of cdma mobile communication system

The CDMA mobile continuous outer-loop power control device and method for a physical channel is a communication system, the data in the DTX mode, only power control bits transmitted without the disclosed. And this power control device according to the present invention comprises an outer-loop power controller having a channel for transmitting the frame to the discontinuous transmission mode and controlling the outer-loop power control. CRC error detector when a frame is received, checking for errors in the frame and outputs a CRC error check result. Frame detector outputs by measuring the energy of the frame. Signal-to-noise ratio calculator, and outputs the calculated signal-to-noise ratio. Sequence detector generates and outputs a frame existence flag message indicating the presence or absence of a frame receiving the CRC error check result and the frame energy. A frame error detector estimates a frame error by the signal-to-noise ratio, it is determined if it is determined that there is received by the frame existence flag message frame output a CRC error check result to the outer-loop power controller, and being free of the frame and outputs it. Also, the device according to the invention is provided with a unit that compensates the offset threshold according to state transition to reduce the time to converge to the threshold value which is set after the transition from the old threshold value of the previous state during outer-loop power control. Also, although an traffic signal to be transmitted while the transmit power of the control signal is intermittent in the intermittent transmission mode to the minimum occurs, to ensure the reception performance by adjusting the gain of the transmit power of the traffic signal. Discontinuous transmission mode, the outer-loop power control, closed loop power control, a frame error, the signal-to-noise ratio, a bit energy
