User equipment and scheduling devices

Abstract

To provide user equipment (UE) capable of distributing and indicating multiple non-overlapping frequency regions by using single downlink control information (DCI) based scheduling for associating the indicated TCI (Transmission Configuration Indication) state with that frequency domain, and a method of a scheduling node.SOLUTION: The DCI carries a TCI indicator specifying that two or more TCI states are set and a frequency domain resource allocation indicating the frequency domain resources allocated for the two or more TCI states. One or more frequency regions are determined for each TCI state of the two or more TCI states. Each region has an integer multiple of a precoding resource block group (PRG), the integer is greater than or equal to 1, and the regions of different TCI states do not overlap. Data is received or transmitted to each TCI state on the frequency domain resources to be determined.SELECTED DRAWING: Figure 10
