1. A transmission apparatus comprising:
code block segmentation circuitry configured to output, based on an input of a transport block with a Cyclic Redundancy Check (CRC), a code block or a plurality of code blocks, each code block of the plurality of code blocks having a same size; and
encoding circuitry configured to generate encoded bits by applying a Low Density Parity Check (LDPC) coding on the code block or on each block of a plurality of blocks that are respectively derived from the plurality of code blocks, wherein
in a case that a first size of the transport block with the CRC is larger than a second size, the transport block with the CRC is segmented into the plurality of code blocks by the code block segmentation circuitry and respectively deriving the plurality of blocks from the plurality of code blocks comprises adding a respective further CRC to each code block of the plurality of code blocks,
the second size is given based on whether a generation method for a matrix for the LDPC coding is a first generation method or a second generation method; and,
wherein the transmission apparatus is configured:
to select a first value by the transmission apparatus from the first value and a second value, which is different from the first value, as the second size in a case that the generation method for the matrix for the LDPC coding is the first generation method, and
to select the second value by the transmission apparatus from the first value and the second value as the second size in a case that the generation method for the matrix for the LDPC coding is the second generation method.
