Method for performing encoding on basis of parity check matrix of ldpc code in wireless communication system and terminal using same

A transmitting device configured to encode, based on a parity check matrix of a low-density parity-check code, information for transmission over a communication channel, the transmitting device comprising:

• a transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• determining the parity check matrix of dimensions at least 5Z rows and 27Z columns comprising 5 rows and 27 columns of Z×Z-sized submatrices that are indexed by submatrix row index m (where 0≤m≤4) and submatrix column index n (where 0≤n≤26), wherein Z is a non-zero integer, and wherein:
• for submatrix row index m=0 and for submatrix column indices n={0, 1, 2, 3, 5, 6, 9, 10, 11, 12, 13, 15, 16, 18, 19, 20, 21, 22, 23}, each submatrix at submatrix index (m, n) is obtained based on a respective value among {223, 16, 94, 91, 74, 10, 0, 205, 216, 21, 215, 14, 70, 141, 198, 104, 81, 1, 0},
