METHOD FOR PERFORMING CODING BASED ON LDPC CODE PARITY CHECK MATRIX IN WIRELESS COMMUNICATION SYSTEM AND TERMINAL USING THEREOF Russian patent published in 2020 - IPC H03M13/11 H04L1/00 

FIELD: wireless communication equipment.

SUBSTANCE: group of inventions relates to wireless communication and can be used to perform coding based on a parity check matrix of the LDPC code in a wireless communication system. Method comprises steps of: determining, by a transmitting device, a parity check matrix comprising at least 5 Z rows and 27 Z columns, wherein the parity check matrix comprises a plurality of submatrices, each of which has dimensions Z × Z for a non-zero integer Z, wherein the submatrix (m, n) of the parity check matrix, which is m^th in the direction of rows of the parity check matrix and n^th in the direction of columns of the parity check matrix, is obtained by means of cyclic shift of columns of unit matrix of size Z × Z to the right by the value of a_{m, n} shift index, which is set by applying the modulo operation to the appropriate value by Z, generating encoded data by a transmitting device based on information encoding with a defined parity check matrix and transmitting the encoded data.

EFFECT: technical result is increased throughput capacity when transmitting a large block with a relatively large length.
