Method and apparatus for re-transmission control

The present invention relates to a method and apparatus that are capable of executing the error correction decoding process while controlling the increase in the amount of data that is stored in the receiving apparatus. There is provided a transmitting apparatus for transmitting the data to a receiving apparatus to execute the error correction decoding process using, for example, the received data and the re-transmitted data, comprising a transmitting data generating means for generating a first transmitting data (BLOCK 0)by executing the rate matching process to a first part of the error correction coded data and generating a second transmitting data (BLOCK F) including at least the data not included in the first part by executing the rate matching process on the basis of the error correction coded data, and a transmitting means for executing the transmission of the second transmitting data as the re-transmission after the transmission of the first transmitting data.
