Abstract
Provided is a wireless communication system employing network coding which can set transmission quality for each destination of packets and improve throughput. The wireless communication system is provided with a wireless relay station apparatus and wireless terminal station apparatuses. The wireless relay station apparatus selects coding rates to be used for a first packet and a second packet in accordance with communication quality required for the first packet and the second packet, generates error correction encoded packets having the same data length from the first packet and the second packet using the selected coding rates, performs network encoding on the error correction encoded first and second packets to generate a network encoded packet, and transmits the generated network encoded packet. The wireless terminal station apparatus performs error correction encoding on a third packet equal to one of the first and second packets, performs network decoding on a received network encoded packet using the error correction encoded third packet to generate a decoded packet, and performs error correction decoding.
