Apparatus and method for transmitting common control information in a wireless communication system

The present invention was sorted and characterized by the second information received only in a wireless communication system, the common control information and the first information that must be received by all subscriber stations serviced by the base station, a particular subscriber terminal of the subscriber station and transmitting by applying the MCS level has a coding manner: (modulation and coding scheme MCS) modulation method of the minimum order of the level and the minimum coding rate, all possible providing the first information in the base station modulation and coding scheme by transmitting the application of the second information for the particular access terminal in a previously set setting than the MCS level corresponding to each channel state level-adjusted MCS levels to maximize the efficiency of radio resources.
