Abstract: A communication device: performs LBRM for storing, in a circular buffer having the length N_IR, N_IR coded bits from among coded bits obtained by performing encoding on the basis of a polar code; performs rate matching on coded bits stored in the circular buffer; and transmits the rate-matched coded bits to another communication device. The communication device stores, in the circular buffer, last N_IR bits from among the coded bits if a code rate is less than or equal to a predetermined value, and, if not, stores first N_IR bits in the circular buffer.

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.
