FIELD: physics.
SUBSTANCE: said utility invention relates to a system and a method for transmitting control information in a mobile communication system. The uplink control information transmission method in a communication system using the orthogonal frequency division multiple access (OFDMA) method is based on the following: the mobile station (MS) selects the target binding base station (BS), which the MS intends to establish communication with, and transmits a code combination assigned to the selected target binding BS, to the current binding BS through a fast uplink channel; after the code combination is received, the fast uplink channel assignment information for the selected BS, corresponding to the code combination received, is transmitted to the MS via the binding BS, the MS switches to the new binding BS corresponding to the fast uplink channel assignment information.
EFFECT: fast cell handover in communication system and transmission of various control information.
