Abstract

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. An encoding apparatus may obtain state-indicator information indicating a state of each of bits included in the polar code based on an index set of the bits, identify a weak-bit or a second weak-bit corresponding to a parity bit candidate position preset according to an interconnection within a parity-check (PC)-chain of the polar code and between PC-chains of the polar code as a parity bit, based on a number of weak-bits determined according to the state-indicator information and a number of bits to be used as parity bits, and obtain a polar code including the identified parity bit.
