Section: 16.3.3.2 Handling of Slice Resources
Content: The NG-RAN node may use Multi-Carrier Resource Sharing or Resource Repartitioning to allocate resources to a slice during the procedures described in 16.3.4 to support the slice service continuity in case of slice resources shortage. In Multi-Carrier Resource Sharing the RAN node can setup the dual connectivity or carrier aggregation with different frequency and overlapping coverage where the same slice is available. The Resource Repartitioning allows a slice to use resources from the shared pool or/and prioritized pool when its own dedicated or prioritized resources are not available and the use of unused resources in the prioritized pool is as specified in TS 28.541[ Management and orchestration; 5G Network Resource Model (NRM); Stage 2 and stage 3 ]  [49]. Slice RRM policies/restrictions associated with Resource Repartitioning are configured from O&M. Measurements of RRM policy utilization according to resource types defined in TS 28.541[ Management and orchestration; 5G Network Resource Model (NRM); Stage 2 and stage 3 ]  [49] are reported from RAN nodes to O&M and may lead O&M to update the configuration of the Slice RRM policies/restrictions.
