摘要：A rate matching method for a polar code is provided, where the methodincludes: acquiring a congruential sequence according to a code length of a target polarcode; performing sorting processing on the congruential sequence according to a preset

rule, to acquire a reference sequence; determining a mapping function according to thecongruential sequence and the reference sequence; and interleaving the target polarcode according to the mapping function, to generate interleaved output bits. Thecongruential sequence is determined based on the code length of the polar code, andinterleaving of the target polar code is implemented by using the congruential sequence,which can enable a sequence of bits obtained after the interleaving to have a moreuniform structure, can reduce a frame error rate and improve HARQ performance,thereby improving reliability of communication; can be applicable to rate matchingprocesses of polar codes of various code lengths, and has good commonality andpracticality.
