Abstract: A method by which a terminal performs rate matching for a low density parity check (LDPC) code can comprise the steps of: determining any one transport block size (TBS) among a plurality of TBSs set for rate matching in the terminal; and performing rate matching for the LDPC code on the basis of the selected TBS. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

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.
