  • Patent number: 11139836
    Abstract: In a wireless communication system, a transmission device generates (K+J) bits by adding J cyclic redundancy check (CRC) bits to K information bits, and interleaves the (K+J) bits according to a seed value-based interleaving pattern. The transmission device encodes the bits interleaved according to the interleaving pattern, using a polar code. The seed value permutates the CRC bits, and a value previously determined according to K is used as the seed value.
