Abstract: Embodiments of this application provide a method for transmitting encoded information. A communication device obtains K bits of information, and generates a to-be-encoded sequence u1N, wherein N is a length of the sequence. The device encodes the sequence u1N in an encoding process, to obtain an output sequence, and transmits the output sequence. In the sequence u1N, each of the N bits corresponds to a subchannel, and each subchannel has a reliability. The K information bits, a quantity J of first-type auxiliary bits, and a quantity J′ of second-type auxiliary bits are placed in K′=K+J+J′ bit positions of the sequence u1N according to reliabilities of the subchannels. Since the positions of the information bits and the auxiliary bits are pre-determined and not affected by subsequent encoding and rate-matching, overheads of real-time reliability calculation are effectively reduced, time is saved, and delay is reduced.

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.
