The disclosure is related to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).A method for operating a first device in a wireless communication system includes receiving information bits and distributed cyclic redundancy check (CRC) bits from a second device, and decoding the information bits and the distributed CRC bits, wherein the information bits and the distributed CRC bits are decoded by using a successive cancellation list decoding scheme that uses a parity check matrix determined based on a linear combination of rows of a predetermined parity check matrix, or by using a successive cancellation flip decoding scheme that uses the distributed CRC bits.
