Abstract: PURPOSE: A communication system supporting a plurality of bandwidths and a feedback resource allocating method thereof are provided to reduce the overhead of the control message by identifying the ACK/NACK feedback resources corresponding to each transmission data channel without the additional information for the position of ACK/NACK feedback resource. CONSTITUTION: The feed back channel signal for a first bandwidth is mapped to the resource of the control area in a subframe which is distinguished as the control areas(410a, 410b) and the data area(420a, 420b). A feedback channel signal of a second bandwidth is mapped into the resource of the data area.
