Abstract: This application provides an information transmission method, a network device, and a terminal device. The method includes: generating, by a network device, downlink control information DCI; determining, by the network device, a corresponding processing manner based on a format of the DCI; performing, by the network device, processing in the processing manner in an encoding process of the DCI; and sending, by the network device, the processed DCI over a physical downlink control channel PDCCH. The information transmission method provided in this application can resolve a problem of a failure in blind detection on DCI caused by a nested encoding feature of polar encoding. When a terminal device cannot determine the format of the DCI sent by the network device, the network device may use a mapping relationship, and the network device processes DCI of a format in a processing manner.

Abstract: A polar code encoding method and apparatus are provided. The method includes: obtaining a basic sequence, where the basic sequence is a sequence obtained by sorting sequence numbers of polarized channels in descending order or ascending order of reliability, and a length of the basic sequence is L1; determining, based on a maximum encoding length L2 supported by a receiving device, a quantity M of segments of an information bit sequence whose length is N after encoding, where a quantity of bits in the information bit sequence before the encoding is K; and performing polar code encoding on the M segments based on the basic sequence. According to the polar code encoding method, during polar code construction, an encoding device needs to know only a reliability order of min(N/M, L1) polarized channels. In this way, storage overheads of a nested sequence can be effectively reduced, and online computing complexity can be reduced.
