A relay station relays packets between a transmitting station and a receiving station, and when a transmission packet affixed with a packet number is received, the relay station generates a divided data unit by dividing the data included in the transmission packet, then generates a divided packet including the divided data unit affixed with the packet number and dividing position information indicating the dividing position of the divided data unit, and transmits the divided packet to the receiving station. Alternatively, the relay station generates a divided data unit by dividing the data in the received transmission packet, then generates a divided packet including the divided data unit affixed with a new packet number, and transmits the divided packet to the receiving station. An ARQ process is executed using the dividing position information or the new packet number included in the divided packet. |
