Transmission apparatus, reception apparatus, communication method, and integrated circuit

A reception apparatus comprising:

• decoding circuitry configured to decode encoded bits into a plurality of code blocks and configured to output information bits including a transport block and a Cyclic Redundancy Check (CRC), the encoded bits being encoded with a Low Density Parity Check (LPDC) coding, wherein
• the information bits including the transport block and the CRC are divided into the plurality of code blocks with a first size in a case that a second size of the information bits is larger than a third size,
• the third size is given based on a generation method for a matrix for the LDPC coding,
• the third size is a first value in a case that the generation method for the matrix for the LDPC coding is a first generation method, and
• the third size is a second value which is different from the first value in a case that the generation method for the matrix for the LDPC coding is a second generation method which is different from the first generation method.

A method for a transmission apparatus, the method comprising:

• dividing information bits including a transport block and a Cyclic Redundancy Check (CRC) into a plurality of code blocks with a first size in a case that a second size of the information bits is larger than a third size;
• and
• generating encoded bits by applying a Low Density Parity Check (LDPC) coding for each of the plurality of code blocks, wherein
• the third size is given based on a generation method for a matrix for the LDPC coding,
• the third size is a first value in a case that the generation method for the matrix for the LDPC coding is a first generation method, and
• the third size is a second value which is different from the first value in a case that the generation method for the matrix for the LDPC coding is a second generation method which is different from the first generation method.
