Abstract: A quasi-cyclic low density parity check (QC LDPC) code rate matching method is disclosed. According to the rate matching method in the present disclosure, the minimum lifting value can be selected from among lifting values by which a codeword longer than a target code block can be generated. A coding gain through retransmission can be acquired by generating the codeword that is longer than the target code block. In addition, by selecting a lifting value of a proper magnitude, rate matching for information bit sequences of various lengths can be performed.

Abstract: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

Abstract: A method for communication device processing a data block in a low-density parity-check (LDPC) encoder includes the steps of, if a size of a payload is equal to or greater than a prescribed size, performing code block segmentation, and performing encoding in a unit of a code block on code blocks according to the code block segmentation. In this case, the code block segmentation may be performed by a payload size supported by a parity check matrix (H) corresponding to a coding rate of the LDPC encoder.
