1. A method for channel encoding performed by an apparatus in a communication system, the method comprising:
identifying a first block size group based on a block size (Z);
identifying a first matrix corresponding to the first block size group, the first matrix being used for circularly shifting an identity matrix;
identifying a parity check matrix based on the block size (Z) and the first matrix;
encoding input bits based on at least part of the parity check matrix;
performing rate matching of the encoded input bits based on a redundancy version (RV) index; and
transmitting at least part of the encoded input bits based on the rate matching,
wherein an RV index 0 indicates a starting position corresponding to 2Z+lth bit of the input bits,
wherein the first matrix is different from a second matrix corresponding to a second block size group, and
wherein the first matrix and the second matrix correspond to a base matrix.
