Question: In E-UTRAN, which energy saving configurations can be set by Operators for an eNB through O&M, in addition to autonomous cell switch-off?
Option 1: Only re-activation requests for dormant cells owned by the same eNB
Option 2: Re-activation requests for dormant cells owned by a peer gNB, but not for peer eNBs
Option 3: Both re-activation requests for dormant cells owned by a peer eNB and a peer gNB
Option 4: Neither re-activation requests for peer eNBs nor peer gNBs, only cell switch-off policies
Explanation: This is correct because Operators can configure an eNB’s ability to request re-activation of dormant cells owned by both peer eNBs and peer gNBs, showcasing flexibility in managing energy-saving across different network infrastructure generations.
