ABSTRACT:
A mobile communication system includes a base station and mobile stations divided into a plurality of groups. A radio communication device 10 at the base station spreads framed control information using a spreading code, and then transmits it via a control channel to the mobile stations. The radio communication device 10 includes a header spreading code generating section 16 which produces mutually different two spreading codes, and further includes a header adding section 17 which, using the mutually different two spreading codes, double-spreads information about allocation of an access right to corresponding one of the groups and adds the double-spread information as a frame header to a frame body representing the foregoing framed and spread control information.
