Apparatus and method for symbol mapping tfci bits for a hard split mode in a cdma mobile communication

PURPOSE: An apparatus and a method for mapping a symbol of a TFCI(Transport Format Combination Indicator) for an HSM(Hard Split Mode) in a CDMA(Code Division Multiple Access) mobile communication system are provided to encode and decode a TFCI having various input information bits and output code symbols using one encoder/decoder structure. CONSTITUTION: Encoders(200-205) encode the first TFCI with k bits at the first coding rate, output the 3k+1 first TFCI code symbols, encode the second TFCI with 10-k bits at the second coding rate, and output the 31-3k second TFCI code symbols. A symbol arranger(210) multiplexes the first TFCI code symbols and the second TFCI code symbols so that the first TFCI code symbols and the second TFCI code symbols are uniformly distributed, and outputs the multiplexed code symbols through one wireless frame according to the number of transferable code symbols.
