Question: What is the primary purpose of the gNB-CU-UP ID in a 5G network?
Option 1: To authenticate user equipment (UE) during initial access.
Option 2: To uniquely identify the gNB-CU-CP within a gNB.
Option 3: To facilitate communication between gNB-CU-CP and gNB-CU-UP.
Option 4: To uniquely identify the gNB-CU-UP at least within a gNB-CU-CP.
Explanation: The gNB-CU-UP ID is used to uniquely identify the gNB-CU-UP within a gNB-CU-CP, ensuring that each unit can be distinctly recognized and managed within the network. This identification is crucial for efficient communication and resource allocation in a 5G network.
