Question: In an EN-DC (E-UTRAN New Radio - Dual Connectivity) scenario, which of the following best describes the purpose of the 'EN-DC RESOURCE STATUS RESPONSE' message when sent by either the en-gNB or the eNB?
Option 1: To request additional resources for a specific UE (User Equipment) from a neighboring E-UTRAN node.
Option 2: To confirm successful initiation of requested measurements for all included measurement objects to the requesting E-UTRAN node.
Option 3: To notify an E-UTRAN node about a change in the resource allocation for ongoing sessions due to congestion.
Option 4: To request handover preparation for a UE moving from one E-UTRAN node's coverage to another.
Explanation: The correct answer, Option 2, aligns with the described purpose of the 'EN-DC RESOURCE STATUS RESPONSE' message. This message is utilized in the context of Dual Connectivity to ensure seamless communication between different base stations (en-gNB and eNB) regarding the status of requested measurements. Confirming successful initiation of these measurements is crucial for efficient network operation, especially in scenarios where dual connectivity is leveraged to enhance user experience through better resource utilization and reduced latency. This response ensures that both nodes are synchronized in their understanding of the network's operational state concerning specific measurement objects.
