Abstract: A rate matching method for a polar code is provided, where the method includes: acquiring a congruential sequence according to a code length of a target polar code; performing sorting processing on the congruential sequence according to a preset rule, to acquire a reference sequence; determining a mapping function according to the congruential sequence and the reference sequence; and interleaving the target polar code according to the mapping function, to generate interleaved output bits.
