Abstract: Disclosed are a method for dividing a transport block of a low density parity check (LDPC) code and an apparatus therefor. A method for dividing a transport block of an LDPC code according to the present disclosure can improve the performance of the LDPC code by dividing the transport block using a minimum number of code blocks. In addition, it is possible to minimize shortening bits by making the size of some of the code blocks smaller than the size of the other code blocks. Further, it is possible to prevent performance degradation due to a minimum size code block by minimizing the number of the code blocks and performing shortening on a large size code block.
