FIELD: wireless communication equipment.
SUBSTANCE: invention relates to wireless communication and is intended for coding based on a parity matrix of LDPC code in a wireless communication system. A method for performing coding based on a parity matrix of a low-density parity-check code according to the present embodiment comprises steps of: forming a parity matrix by means of a terminal, wherein the parity matrix corresponds to the characteristic matrix, each component of the characteristic matrix corresponds to a value of the shift index, determined through a modulus operation between the corresponding component in the base matrix and Zc, which is a lifting value, and the base matrix is matrix 42×52; and performing encoding of input data by means of a terminal using a parity matrix, wherein the lifting value is associated with the length of the input data.
EFFECT: providing wide coverage / data transfer due to support of different code speeds.
