    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.

    Abstract: A pre-5th generation (5G) or 5G communication system supports higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE) is provided. A method for operating a first device in a wireless communication system includes generating a first bit sequence, generating a second bit sequence including at least one of the first bit sequence, at least one cyclic redundancy check (CRC) bit, at least one frozen bit, or at least one parity check (PC) bit, generating a transmission bit sequence by performing a polar encoding and a rate matching for the second bit sequence, and transmitting, to a second device, the transmission bit sequence. A length of the transmission bit sequence is equal to or greater than a sum of a length of the first bit sequence, a number of the at least one CRC bit and a number of the at least one PC bit.
