3GPP 38.300 v19.3.0 — the document's own text
4.10.4 Access Control
Taught in 4. What NR actually is, in the shape its own document gives it (TSG RAN — the group that specifies the radio, overview).
Cells served by an NR Femto node may be deployed as part of a PNI-NPN (see clause 4.8) in order to restrict access to UEs according to the respective subscription.
NOTE: The NR Femto node may use the CAG mechanism for PNI-NPN (see clause 16.7.4) as follows:
- The NR Femto node may activate a PLMN cell, which can be accessed by legacy UE without access control of CAG;
- The NR Femto physical node may activate a physical cell shared by both PLMN and PNI-NPN, as specified in clause 4.6, through broadcasting both the plmn-IdentityInfoList and the npn-IdentityInfoList-r16 in the SIB1, but without the cellReservedForOtherUse;
- The NR Femto node may activate an NPN-only cell by broadcasting the cellReservedForOtherUse with value "true", then this cell can only be accessed by the UEs whose allowed CAG list includes a CAG-ID broadcasted by the cell.
