Disclosed is a method for transmitting a channel signal in a base station of a mobile communication system which scrambles a common channel signal using a primary scrambling code for identifying the base station. The method comprises determining an identifier (ID) of a secondary scrambling code, upon receipt of a dedicated channel assignment request from a mobile station; transmitting the determined ID of the secondary scrambling code to the mobile station and awaiting a response; upon receipt of a response message from the mobile station, generating a primary scrambling code and a secondary scrambling code using an ID of the primary scrambling code and said ID of the secondary scrambling code; and scrambling a common channel signal using the primary scrambling code, scrambling a dedicated channel signal using the secondary scrambling code, and transmitting the scrambled channel signals.
