Method and coding apparatus for processing information using a polar code

A coding apparatus in a communication device, comprising:

• a memory configured to store program instructions, and one or more processors;
• wherein the processors, by executing the program instructions, are configured to:
• obtain an information bit sequence, wherein the information bit sequence comprises a k-bit information block, wherein information bit sequence is to be processed into an encoded bit sequence with a target code length of M, M is greater than 1024;
• for a given code rate R, when the length K of the information block is greater than a preset threshold, segment the information bit sequence into p segments, wherein p is an integer greater than or equal to 2;
• polar encode each of the p segments, to obtain p encoded subsequences, wherein an encoded subsequence i of the p encoded subsequences has a length that equals to a mother code length Ni, and i=1, 2, . . . , p;
• rate match each of the p encoded subsequences, to obtain p rate-matched encoded subsequences, wherein a rate-matched encoded subsequence i of the p rate-matched encoded subsequences has a code length Mi;
• concatenate the p rate-matched encoded subsequences, to obtain an encoded bit sequence, wherein the encoded bit sequence has a code length of M;
• and
• output the encoded bit sequence.
