Abstract
Embodiments of the present invention disclose a downlink control information (DCI) transmission method, a network device, and user equipment. The method includes the following steps: A network device transmits DCI in a first DCI format; when the DCI is used to schedule a physical downlink shared channel (PDSCH) carrying a multicast traffic channel, the network device indicates, by using a first radio network temporary identifier (RNTI), that the DCI is used to schedule the PDSCH carrying the multicast traffic channel, and that first information is indicated in the DCI and second information is not indicated in the DCI; and when the DCI is used to schedule a user equipment-specific (UE-specific) PDSCH, the network device indicates, by using a second RNTI, that the DCI is used to schedule the UE-specific PDSCH, and that the first information is not indicated in the DCI and the second information is indicated in the DCI.
