FIELD: physics; communications.
SUBSTANCE: device and method are provided for transmitting and receiving a character through a control return channel in a mobile communication system for transmitting data packets. When there is traffic in the reverse direction, the device and method can efficiently demodulate and decode traffic of the reverse direction. In the method of reverse channel transmission in a mobile communication system which is capable of discontinuous transmission of data packets, transmission is carried out by setting data rate indicator (DRI) channel power equal to predefined power when data packets are being transmitted. When data packets are not being transmitted, transmission is carried out by reducing DRI channel power.
EFFECT: efficient demodulation and decoding reverse traffic when there is reverse direction traffic in mobile communication system which supports discontinuous transmission.
