form cell reselection according to the following procedure [8]: Cell reselection is always based on CD-SSBs located on the synchronization raster. The UE measures the attributes of the serving and neighbor cells to facilitate the rese- lection process. The UE would only need information on the carrier frequencies of the inter-frequency neighbor cells, when conducting search and measurement. Cell reselection identifies the cell that the UE should camp on. It is based on cell rese- lection criteria which involves measurements conducted on the serving and the neighbor cells. It must be noted that intra-frequency cell reselection is based on ranking of the cells and inter-frequency cell reselection is based on absolute priorities, where a UE would camp on the highest priority frequency available. A neighbor cell list (NCL) can be provided by the serving cell to facilitate cell selection in specific cases for intra- and inter-frequency neighbor cells. The NCL contains cell- specific cell reselection parameters (e.g., cell-specific offset) for specific neighbor cells. Black lists can be provided to prevent the UE from reselecting to specific intra- and inter-frequency neighboring cells. In multi-beam operations, the cell quality is derived amongst the beams corresponding to the same cell. 2.3.3.2 Inactive Mode Procedures RRC_INACTIVE is a state where a UE remains in CM-CONNECTED state while roaming within an area configured by NG-RAN known as RNA without notifying NG-RAN. In RRC_INACTIVE state, the last serving gNB maintains the UE context and the UE-associated NG connection with the serving AMF and user-plane function (UPF). If the last serving gNB receives downlink data from the UPF or downlink UE-associated signaling from the AMF (except the UE Context Release Command message) while the UE is in RRC_INACTIVE state, it pages the UE in the cells corresponding to the RNA and may send an XnAP RAN Paging 10 to neighbor gNB(s), if the RNA includes cells of neighboring gNB(s). Upon receiving the UE Context Release Command
