1. A method for encoding in a communication or broadcasting system supporting a low density parity check (LDPC) code, the method comprising:
identifying a block size Z;
identifying a parity check matrix, based on the block size Z;
generating codeword, based on input bits and the parity check matrix, wherein the codeword includes parity bits and a first part of the input bits; and
generating coded bits for transmission based on a circular buffer-based rate matching (CBRM) and the codeword;
wherein a second part of the input bits is not included in the codeword.
