Downlink control information transmission method and apparatus
First Claim
1. A downlink control information transmission method, comprising:
- determining multiple terminal devices used for downlink scheduling;
determining downlink control information used by the multiple terminal devices to receive downlink data flows, wherein the downlink control information comprises common control information shared by the multiple terminal devices, dedicated control information of each of the multiple terminal devices, and device identifier information of each terminal device, and an order of the device identifier information of each terminal device is the same as an order of the dedicated control information of each terminal device; and
sending the downlink control information to the multiple terminal devices.
