The BS may collectively mean an object that performs data transmission/reception with the UE. For example, the BS may include one or more TPs (Transmission Points), one or more TRPs (Transmission and Reception Points), and the like. Furthermore, the TP and/or TRP may include a panel, a transmission and reception unit, and the like of the BS. In addition, as described above, the TRP may be distinguished according to information (e.g., index or ID) for a CORESET group (or CORESET pool). In one example, in the case that a single UE is configured to perform transmission/reception with multiple TRPs (or cells), this may mean that multiple CORESET groups (or CORESET pools) may be configured for the UE. A configuration for the CORESET group (or CORESET pool) may be performed through higher layer signaling (e.g., RRC signaling).
The base station may transmit configuration information to the UE (S1410). The configuration information may be transmitted through higher layer signaling (e.g., RRC or MAC-CE).
