Question: In a shared E-UTRA cell connected to 5GC, how many TACs and Cell Identities can be indicated for different subsets of Public Land Mobile Networks (PLMNs) in system information broadcast?
Option 1: One TAC and one Cell Identity for all PLMNs
Option 2: Up to 3 TACs and 3 Cell Identities for different subsets of PLMNs
Option 3: A variable number depending on the E-UTRA configuration, but always more than 6
Option 4: Up to 6 TACs and 6 Cell Identities, each set corresponding to a subset of PLMNs
Explanation: In a shared E-UTRA cell connected to 5GC, the system information broadcast can indicate up to 6 different sets of TAC (Tracking Area Code) and Cell Identity, with each set associated with a distinct subset of Public Land Mobile Networks (PLMNs). This allows for efficient sharing of radio access network resources among multiple PLMNs while maintaining unique identifiers for each subset of PLMNs served by the same ng-eNB node.
