10.7 E-UTRA-NR Cell Resource Coordination

An NR cell may use spectrum that overlaps or is adjacent to spectrum in use for E-UTRA cells. In this case network signalling enables coordination of TDM and FDM cell resources between MAC in the gNB and the corresponding entity in the ng-eNB. Both the gNB and the ng-eNB can trigger the E-UTRA - NR Cell Resource Coordination procedure over Xn to its peer node.
