Section: 7.9 Inter-node Resource Coordination
Content: For MR-DC operations, MN and SN may coordinate their UL and DL radio resources in semi-static manner via UE associated signalling. The MN may coordinate its sidelink radio resources with the SN using the same UE associated signalling. In EN-DC, CSI-RS based SgNB change between neighbour en-gNBs is supported by enabling that neighbour en-gNBs can exchange their own CSI-RS configurations and on/off status via the MeNB. In NGEN-DC and NR-DC, CSI-RS based SN change between neighbour gNBs is supported by enabling that neighbour gNBs can exchange their own CSI-RS configurations and on/off status via the MN.
