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.
