Coding apparatus and method in a cdma mobile communication system

The invention particularly forward-speed transmission (High Speed ​​Downlink Packet Access) in the mobile communication system using a channel for on the code and the decoding of the uplink control information to support the HSDPA in the mobile communication system using the CDMA an apparatus and method. Scheme proposed by the present invention has an advantage capable of providing a code having an optimal performance for the code amount of the reverse control information. HSDPA, HS-DSCH, S_UL_DPCCH, Channel Quality Indicator, Measurement report
