A radio communication system includes a first radio communication apparatus which transmits signals according to cyclic process numbers and a second radio communication apparatus which receives the signals and aims at reducing the possibility of misrecognition occurrence on a reception result (ACK/NACK information). The second radio communication apparatus add the second information element (Other ACK/NACK information element) indicating a reception result of a received signal of another process number to the first information element (Own ACK/NACK information element) indicating a reception result of a received signal of a certain process number, which information elements are transmitted to the first radio communication apparatus. The first radio communication apparatus judges a reception result of the transmitted signal on the basis of the first and the second information elements received from the second radio communication apparatus.
