Abstract: Embodiments of this application provide an information processing method and a coding apparatus. An information bit sequence includes a K-bit information block. The information bit sequence is to be processed into an encoded bit sequence with a target code length M. For a given code rate R, when the length K of the information block is greater than a preset threshold, the information bit sequence is segmented into two or more segments. Each segment is polar encoded into an encoded subsequence. The encoded subsequence has a length that equals to a mother code length Ni, and i=1, 2, . . . , p. Each of the p encoded subsequences is rate matched to obtain a rate-matched encoded subsequence. A rate-matched encoded subsequence i of the p rate-matched encoded subsequences has a code length Mi. The p rate-matched encoded subsequences are concatenated into an encoded bit sequence which has a code length M.

Abstract: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.

Abstract: Embodiments of the application provide a polar coding method for communicating information in a wireless network. Information bits are encoded using a polar code process to obtain a polar-coded bit sequence. A rate matched bit sequence is output based on the polar-coded bit sequence. The rate matched bit sequence includes a quantity M of bits from the polar-coded bit sequence, and the M bits from the polar-coded bit sequence correspond to M channel indexes in a channel index sequence S. The channel index sequence S is obtained based on a puncturing/shortening proportion P′ and a prestored channel index sequence S′. Channel indexes in the prestored channel index sequence S′ are sorted by channel reliability or channel capacity, and a sorting order of the M channel indexes in the channel index sequence S is the same as a sorting order of the channel indexes in the prestored channel index sequence S′.
