1. An encoding method in a wireless communication system, the method comprising:
determining, for a transport block, whether a first criteria is met, wherein the first criteria includes a coding rate (R) is less than or equal to 1/4;
determining, for the transport block, whether a second criteria is met, wherein the second criteria includes a transport block size (TBS) is less than or equal to 3824 bits and the R is less than or equal to 2/3;
encoding, based on determining that at least one of the first criteria and the second criteria is met, one or more code blocks of the transport block using low-density parity-check (LDPC) base graph 2, wherein a maximum code block size is 3840 bits;
determining that none of the first criteria nor the second criteria are met;
based on the determining that none of the first criteria nor the second criteria are met, encoding the one or more code blocks using LDPC base graph 1; and
transmitting the transport block.
