Abstract
A radio communication system of an HARQ method that makes an HARQ transmission interval of subpackets appropriate and reduces data transmission delay resulting from subpacket retransmission. In the radio communication system in which a packet is transmitted and receives with the HARQ method between a base station and multiple radio mobile stations, each of the base station and the multiple radio mobile stations has: a packet transmission circuit for transmitting subpackets in predetermined intervals; a packet reception circuit for repeating decoding processing by combining a newly received subpacket and a previously received former subpacket until an original packet is successfully decoded; and a HARQ control equipped with a function of, for packet communication whose data length is short, transmitting a subpacket or response from the packet transmission circuit in an HARQ transmission interval that is shortened from the HARQ transmission interval of the normal mode.
