Document Type and Number:
Japanese Patent JP6817452
Kind Code:
B2
Abstract:
Embodiments of this application provide a coding method, a coding apparatus, a communication apparatus, a decoding method, a device and a computer readable storage medium. The method includes: obtaining an information bit sequence and a target code length M of a polar code, a quantity of information bits in the information bit sequence is K, wherein K, M are positive integers; when the target code length M meets a preset condition, using a polar code with a first mother code length N1 to encode the information bit sequence, to output a first encoded bit sequence having a length of N1, wherein N1=2n and n is an integer less than or equal to log2M; and performing rate matching by repeating at least some bits in the first encoded bit sequence, to obtain a first target polar code with a length M; wherein the preset condition comprises one of: a first code rate R1 is less than or equal to a second code rate R2 that is preset, wherein the first code rate R1 is equal to K/ N1; or a difference between the target code length M and the first mother code length N1 is less than a predetermined range.
