Section: 4.6 Radio Access Network Sharing
Content: NG-RAN supports radio access network sharing as defined in TS 23.501[ System architecture for the 5G System (5GS) ]  [3]. If NR access is shared, system information broadcast in a shared cell indicates a TAC and a Cell Identity for each subset of PLMNs, PNI-NPNs and SNPNs. NR access provides only one TAC and one Cell Identity per cell per PLMN, SNPN or PNI-NPN. In this version of the specification, a Cell Identity can only belong to one network type among PLMN, PNI-NPN or SNPN as defined in TS 23.501[ System architecture for the 5G System (5GS) ]  [3]. Each Cell Identity associated with a subset of PLMNs, SNPNs or PNI-NPNs identifies its serving NG-RAN node.
