Question: What is a primary challenge in optimizing RAN UE (User Equipment) throughput in radio networks, according to the complexities of adjusting feature configurations?
Option 1: Insufficient network coverage leading to dropped calls.
Option 2: The interdependence of numerous radio feature parameters with broad value ranges.
Option 3: Limited availability of spectrum for resource scheduling.
Option 4: High latency in handover processes between cells.
Explanation: Optimizing RAN UE throughput is complicated due to the vast number of radio feature parameters (e.g., related to mobility, resource scheduling, cell reselection, and handover) that affect each other. This interdependence creates a large combination of potential parameter values, making manual adjustment for optimal throughput complex. Thus, understanding the impact of these interconnected parameters is crucial for effective optimization.
