Question: What is the primary purpose of the RRC Transfer procedure in E-UTRAN, as it relates to the exchange of Radio Resource Control (RRC) messages between the Master eNodeB (MeNB) and the secondary eNodeB (en-gNB)?
Option 1: To manage the handover of User Equipment (UE) from one cell to another within the same eNodeB.
Option 2: To facilitate the transfer of LTE/NR RRC messages, including measurements, failure information, and reconfiguration completions, between MeNB and en-gNB for UE-associated signaling.
Option 3: To establish or modify bearer contexts for Quality of Service (QoS) management in E-UTRAN.
Option 4: To synchronize the MeNB and en-gNB for coordinated multipoint (CoMP) transmission schemes.
Explanation: The RRC Transfer procedure's primary purpose is to transfer various LTE/NR RRC messages, including measurements, failure information, and reconfiguration completions, between the MeNB and en-gNB, specifically for UE-associated signaling, ensuring efficient management of UE communications across different nodes.
