1. A multi-transmission node transmission method, comprising:
generating, by a network device, a downlink control information (DCI) corresponding to each of a plurality of transmission nodes and corresponding to each of a plurality of code words that is to be sent to a terminal device from a transmission node;
scheduling, by the network device, a physical downlink shared channel (PDSCH) corresponding to each of the plurality of transmission nodes and corresponding to the DCI; and
sending, by the network device, the DCI corresponding to each of the plurality of transmission nodes to the terminal device, wherein the DCI is used by the terminal device to demodulate data for the code word that is carried on the PDSCH corresponding to the transmission node with a channel feature comprising parameters including a received angle of arrival, a primary angle of arrival, and a received angle of arrival spread.
