Question: In a 3GPP-compliant FDD network, what entity is responsible for controlling MBMS (Multimedia Broadcast Multicast Service) combining?
Option 1: User Equipment (UE)
Option 2: Network (e.g., eNodeB or RAN)
Option 3: Serving and Gateway Core Network Nodes
Option 4: Mobile Switching Center (MSC)
Explanation: MBMS combining is an autonomous process handled by the User Equipment (UE) itself, without direct control from the network. This allows the UE to dynamically manage reception of broadcast/multicast services across different cells, enhancing service quality and availability. The UE's ability to identify neighbor cells and adjust based on RLC SDU error rates underscores its primary role in this process.
