Abstract: A Polar code rate matching method and a rate matching apparatus are disclosed. The method includes: dividing a system Polar code output by a Polar code encoder into system bits and parity bits; interleaving the system bits to obtain a first group of interleaved bits, and interleaving the parity bits to obtain a second group of interleaved bits; and determining a rate-matched output sequence based on the first group of interleaved bits and the second group of interleaved bits.
