Question: What is the primary objective of the EN-DC Cell Activation procedure in E-UTRAN, as related to cell management between eNB and en-gNB?
Option 1: To handle UE handovers between activated cells of neighboring base stations.
Option 2: To synchronize cell ID assignments across different en-gNBs for seamless user experience.
Option 3: To enable an eNB to request a neighboring en-gNB to activate previously inactive cells due to energy-saving measures.
Option 4: To optimize resource allocation for active UEs in areas with overlapping cell coverage.
Explanation: The correct answer, Option 3, aligns with the procedure's purpose. EN-DC Cell Activation allows an eNB to request activation of cells on a neighboring en-gNB that were turned off for energy-saving reasons, utilizing non UE-associated signaling.
