Patent ID: 11528036

Abstract:
A method for transmitting an information block on the basis of a low density parity check (LDPC) code in a wireless communication system, according to the present disclosure, may comprise: encoding an information block on the basis of a LDPC basegraph H_BG including [MATRIX]; and transmitting the encoded information block. Each element of H_BG is either zero (“0”) or one (“1”), and each element which is “0”, among the elements of H_BG, may represent a Z×Z zero matrix, and each element which is “1”, among the elements of H_BG, may represent a Z×Z matrix acquired on the basis of a circular permutation matrix acquired by circularly shifting a Z×Z identity matrix to the left or right. The submatrix T_BG of H_BG may be a dual diagonal matrix, and the submatrix D_BG of H_BG may be a dual diagonal matrix. The encoding of the information block on the basis of H_BG may comprise encoding the information block on the basis of a parity check matrix (PCM) H which corresponds to H_BG.
