Classification: CPC H | IPC H

Claim 9:
10. A method for a reception apparatus, the method comprising:
decoding encoded bits into a code block or a plurality of code blocks, each code block of the plurality of code blocks having the same size, and outputting, based on the code block or the plurality of code blocks, a transport block with a Cyclic Redundancy Check (CRC), the encoded bits having been generated at a transmission apparatus by applying a Low Density Parity Check (LDPC) coding on the code block or on each block of a plurality of blocks that have respectively been 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 has been segmented at the transmission apparatus into the plurality of code blocks, 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,
a first value is selected 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
the second value is selected 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.
