Question: What is the purpose of the E-UTRA-NR Cell Resource Coordination procedure between a gNB and an ng-eNB?
Option 1: To manage handovers between LTE and NR cells.
Option 2: To coordinate TDM and FDM cell resources when NR and LTE cells use overlapping or adjacent spectrum.
Option 3: To optimize network performance during peak hours.
Option 4: To enable dual-connectivity for User Equipment (UE).
Explanation: The E-UTRA-NR Cell Resource Coordination procedure is used to coordinate TDM and FDM cell resources between the MAC in the gNB and the corresponding entity in the ng-eNB when NR and LTE cells use overlapping or adjacent spectrum. This ensures efficient use of radio resources and minimizes interference between the two types of cells.
