polar method and apparatus, and polar method and apparatus

摘要

embodiments of this application provide a polar coding method and apparatus. in the encoding method, a sequence of bits of information to be encoded is divided into a plurality of segments when an encoding parameter meets a predefined segmentation condition; polar coding and rate matching are performed separately on the plurality of segments; and a plurality of encoded bit strings obtained is concatenated to obtain a final encoded bit sequence. in a specific condition, the segmentation-based encoding method can reduce time to use a repetition-based rate matching scheme and can reduce a performance loss caused by repetition.
