Question: What is the primary purpose of the `CondReconfigId` Information Element in Radio Resource Control (RRC) protocol?
Option 1: To authenticate User Equipment (UE) during initial access to a 5G network.
Option 2: To identify a Configuration for Cell (CHO), Per-UE Computing and Processing Ability (CPA), or Computing and Processing Capability (CPC).
Option 3: To manage Quality of Service (QoS) parameters for ongoing data sessions.
Option 4: To signal handover decisions between different Radio Access Technologies (RATs).
Explanation: The `CondReconfigId` is used to identify specific configurations related to Cell, Per-UE Computing and Processing Ability, or Computing and Processing Capability. This identification is crucial for efficient radio resource management in 5G networks, ensuring the right configurations are applied. The other options describe unrelated functions: UE authentication, QoS management, and inter-RAT handovers.
