Question: What is the primary purpose of the ng-eNB-DU ID in the NG-RAN architecture?
Option 1: To uniquely identify the ng-eNB-CU within an ng-eNB-DU.
Option 2: To authenticate the ng-eNB-DU during the W1 Setup procedure.
Option 3: To uniquely identify the ng-eNB-DU at least within an ng-eNB-CU.
Option 4: To authorize the ng-eNB-DU to access the W1AP procedures.
Explanation: The ng-eNB-DU ID is used to uniquely identify the ng-eNB-DU within an ng-eNB-CU, which is essential for proper communication and resource allocation between the ng-eNB-DU and ng-eNB-CU. This identification is crucial for the W1 Setup procedure and subsequent W1AP procedures.
