Methode of transmitting control data in cdma mobile communication system

PURPOSE: A method for transmitting control data in a CDMA(Code Division Multiple Access) mobile communication system is provided to use a UL-DPCCH(UpLink- Dedicated Physical Control CHannel) irrespective of using an HSDPA(High Speed Downlink Packet Access). CONSTITUTION: A pilot signal, a TFCI(Transmit Format Combination Indicator) bit, a downlink power control command signal, dedicated channel data, and a downlink dedicated physical control channel signal including high speed packet data indication information for designating a common control channel are transmitted. Control information necessary for receiving high-speed packet data in a terminal is transmitted on a common control channel designated by high-speed packet data indication information. The high-speed packet data are spread using a spreading code included in control information transmitted on the common control channel and are transmitted a high-speed physical common channel.
