Abstract: Embodiments of this application provide a method for processing information bits. A communication device obtains K information bits and a code length M. The code length M is a length of an output sequence resulting from processing the information bits. The communication device generates an N-bit bit sequence that includes the K information bits and one or more parity check bits, encodes the bit sequence using a polar encoding formula to obtain an N-bit encoded sequence, rate matches the encoded sequence to obtain the output sequence, modulates the rate matched sequence to obtain output sequence and outputs the output sequence. When M−K>192, in the bit sequence, one of the parity check bits is placed in a bit position that is determined according to reliabilities of the bit positions in the bit sequence for placing the K information bits and the one or more parity check bits.

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 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, M>1024. 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.
