There is provided a data communication apparatus and method in a multi-carrier CDMA communication system. A transmitting device determines whether a supplemental channel is transmitted. If the supplemental channel is transmitted, the transmitting device assigns the supplemental channel to each of all FAs having different carrier frequency bands and the other channels including a fundamental channel, a dedicated control channel, and a common control channel to one of the FAs. A receiving device determines whether the supplemental channel exists in input channel signals. If the supplemental channel exists, the receiving device despreads supplemental channel signals in each of the FAs, connects the despread supplemental channel signals to a supplemental channel decoder, despreads the other channels in one of the FAs, and connects the other channel signals to corresponding channel decoders.
