Claim:
1. A communication system comprising: a plurality of communication apparatuses for carrying out a radio communication by assigning a plurality of carriers to a second frequency band with a predetermined bandwidth to be exceeded by carriers with a first frequency bandwidth serially assigned, the communication system assigning each of the carriers to the second frequency band in such a manner as to overlap a portion of each of the carriers, and a first communication apparatus using one of the carriers having the overlapping portion and a second communication apparatus using an other carrier dividing the overlapping portion by a radio resource as a unit based on a frequency and time into ranges to be used by the each of the communication apparatus preferentially, and the first communication apparatus and the second communication apparatus receive, at the same timing, only control data from mobile stations by preferentially using respective radio resources obtained by dividing the overlapping portion.
