Provided is a method for rate matching of a polar code. The method comprises: acquiring a congruential sequence according to the 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 interweaving the target polar code according to the mapping function to generate an interwoven output bit. By way of determining a congruential sequence based on the code length of a target polar code, and realizing interweaving on the target polar code via the congruential sequence, an interwoven bit sequence structure can be enabled to be more uniform, a frame error rate can be reduced, and HARQ performance can be improved, thereby improving the reliability of communications; furthermore, being able to be applied to a rate matching process with respect to polar codes of various code lengths, and having good generality and practicability. |
