Abstract: This application provides example downlink control information transmission methods and apparatuses. In an example method, a terminal device receives first configuration information. The first configuration information may indicate the terminal device to monitor a physical downlink control channel (PDCCH) candidate in a first scheduling cell and a second scheduling cell.
