Downlink Control Information (DCI) Communication Method and Communication Equipment

Abstract

The invention proposes a method for transmitting Downlink Control Information (DCI) and a transmission device. The method includes: DCI is implemented, in which DCI includes Frequency Domain Resource Allocation (FDRA) information. FDRA information is used to identify the N frequency domain resource groups. These N frequency domain resource groups are the N groups of frequency domain resources used by the communication equipment to transmit the Physical Downlink Shared Channel (PDSCH). The N frequency domain resource groups correspond to N spatial information indicators, and N is an integer greater than or equal to 2.
