Patent ID: 8295221

Claim:
A wireless communication apparatus that receives a plurality of first packets from a first wireless communication apparatus and a plurality of second packets, which is collectively greater than the plurality of first packets in an amount of data, from a second wireless communication apparatus and that transmits a third signal, which has the same amount of data as the plurality of second packets collectively, to the first wireless communication apparatus and the second wireless communication apparatus, the wireless communication apparatus comprising: an error-correction encoder configured to generate a plurality of redundant packets by reducing an encoding rate of an earliest received packet included in the plurality of first packets in accordance with respective influence degrees on a transmission delay; and a coder configured to generate the third signal by combining a first signal, which is generated by appending the plurality of first packets together and arranging the plurality of redundant packets in free resources of the first signal so as to distribute a greater amount of free resources to packets imposing a larger influence degree on the transmission delay, with a second signal, generated by appending the plurality of second packets, in a separable manner.
