Abstract: This application provides a downlink control information transmission method and an apparatus. A network device determines that a terminal device is in the first transmission mode in which the terminal device demodulates a PDSCH based on a DMRS. The network device sends a first PDSCH and first DCI to the terminal device. The first DCI includes a first field. The first field indicates, based on a resource allocation type 2, a resource position occupied by the first PDSCH. The terminal device may demodulate the first PDSCH at the resource position indicated by the first field. An existing DCI format indicates a resource position based on a resource allocation type 0 or a resource allocation type 1. The first DCI indicates a resource position based on the resource allocation type 2.
