<P>PROBLEM TO BE SOLVED: To provide a radio communication system enabling a transmission station to promptly receive error packet information from a reception station while multicast communication using a plurality of frequencies is performed. <P>SOLUTION: The radio communication system includes a transmission station 1-1 that transmits identical transmission data to a plurality of reception stations 1-2, 1-3, and 1-4. The transmission station divides the transmission data into a plurality of data blocks, and transmits the divided transmission data in parallel to the plurality of reception stations, using mutually different frequencies F1, F2, and F3. Each reception station returns an error response packet relative to the transmission data transmitted from the transmission station. The error response packet at this time is returned by use of at least one of the following methods: for each different frequency, returning error packet response information relative to the transmitted transmission data, to the transmission station in time division using the frequency of concern; and returning a plurality of sets of error packet response information corresponding to the plurality of transmission data blocks, respectively transmitted using the plurality of different frequencies, to the transmission station using one of the plurality of different frequencies. <P>COPYRIGHT: (C)2012,JPO&INPIT |
