Abstract:
1. A communication apparatus comprising: a receiving section that receives a signal including a transmission request or a retransmission request; a setting section that sets one of (i) a first transmission method for transmitting data in accordance with the transmission request and transmitting a retransmission signal when the retransmission request is received, the retransmission signal including at least part of the data previously transmitted by the communication apparatus, and (ii) a second transmission method for transmitting an erasure correction coding signal obtained by erasure correction coding of the data in accordance with the transmission request; a signal generating section that outputs one of the erasure correction coding signal, the data and the retransmission signal; and a modulating section that modulates a signal output from the signal generating section, wherein: when the second transmission method is set, the signal generating section outputs the erasure correction coding signal, when the first transmission method is set and the transmission request is received, the signal generating section outputs the data, and when the first transmission method is set and the retransmission request is received, the signal generating section outputs the retransmission signal.
