Question: What is a key requirement for the 5G system when handling data transfer from stationary UEs, such as those with lower signaling to user data resource usage ratio?
Option 1: Maximize control and user plane resource usage
Option 2: Minimize control and user plane resource usage
Option 3: Optimize only the control plane for resource usage
Option 4: Prioritize high-speed data transfer over low latency
Explanation: The correct answer is Option 2 because, according to the text, "The 5G system shall minimize control and user plane resource usage for stationary UEs (e.g. lower signalling to user data resource usage ratio)". This indicates that one of the key requirements for the 5G system is to reduce unnecessary resource consumption when dealing with stationary UEs, which typically have a lower signaling to user data resource usage ratio.
