<p>PROBLEM TO BE SOLVED: To provide a multicarrier mobile communication system capable of increasing efficiency at each re-transmission.SOLUTION: A transmitter includes coding means for generating a transmission signal by dividing transmission data into a plurality of code blocks, then coding each of the plurality of code blocks, and transmission means for transmitting the transmission signal. A receiver includes a reception means for receiving the transmission signal as a reception signal. The reception means transmits re-transmission request feedback information, in which NACK information representing an existence of an error in the transmission signal and information representing a specific code block within the plurality of code blocks in the reception signal are included, to the transmitter if an error exists in the reception signal. A first resource is allocated to each of the plurality of code blocks in the transmission signal. The transmission means allocates a resource of the specific code block within the plurality of code blocks in the transmission signal into a second resource, different from the first resource, according to the re-transmission request feedback information, and then re-transmits the transmission signal to the receiver.</p> |
