Abstract
A polar code coding/decoding method, a sending device, and a receiving device are disclosed. The method includes: selecting, by a sending device, K non-punctured-position sequence numbers as a reference sequence number set based on a quantity K of information bits and a reliability-based order of N polarized channels of a polar code whose code length is N, where a reliability of a polarized channel corresponding to any sequence number in the reference sequence number set is greater than or equal to reliabilities of polarized channels corresponding to remaining (N−K) sequence numbers; determining, by the sending device, an information-bit sequence number set based on a determining condition and the reference sequence number set; and performing, by the sending device, polar coding on to-be-coded bits based on the information-bit sequence number set.
