Abstract
This disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to a method for encoding and decoding a channel in a communication or broadcasting system, comprising the steps of determining an input bit size (CBS), determining a code rate (R), determining a size (Z) of a block, comparing the determined CBS and code rate with predetermined reference values, determining an LDPC sequence to perform LDPC encoding according to the comparison result, and performing LDPC encoding and decoding on the basis of the LDPC sequence and the block size. Further, the present invention comprises the steps of determining a code rate (R) indicated by a modulation and coding scheme (MCS) index, determining a transport block size, and determining either a first basic matrix or a second basic matrix as a basic matrix on the basis of the transport block size and the code rate.
