Section: 19.6A NR Cell Identity (NCI) and NR Cell Global Identity (NCGI)
Content: The NR Cell Global Identity (NCGI) shall be composed of the concatenation of the PLMN Identifier (PLMN-Id) and the NR Cell Identity (NCI) as shown in figure 19.6A-1 and shall be globally unique: Figure 19.6A-1: Structure of NR Cell Global Identity The NCI shall be of fixed length of 36 bits and shall be coded using full hexadecimal representation. The exact coding of the NCI is the responsibility of each PLMN operator. For more details on NCI and NCGI, see 3GPP TS 38.413[ NG-RAN; NG Application Protocol (NGAP) ]  [123]. NOTE: In the 5G Core Network protocols, when the NCGI needs to be identified in the context of Standalone Non-Public Networks (SNPN), the Network Identifier (NID) of the SNPN is included as part of the NCGI Information Element (see 3GPP TS 29.571[ 5G System; Common Data Types for Service Based Interfaces; Stage 3 ]  [129]); this is a protocol aspect that does not imply any change on the system-wide definition of the NCGI.
