The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An encoding method using a polar code in a wireless communication system, according to an embodiment of the present disclosure, may comprise: generating first cyclic redundancy check (CRC) bits for a plurality of information bits to be transmitted, by the number of second bits that is less than the number of first bits determined so as to add a CRC code with respect to the plurality of information bits; for vulnerable bits from among the plurality of information bits to be transmitted, generating second CRC bits as many as bits corresponding to a difference between the number of first bits and the number of second bits; generating first encoded bits in which the information bits, the first CRC bits, and the second CRC bits are concatenated; and polar-encoding the first encoded bits.
