Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay stations are measured in field conditions, then measurement realism is improved, but measurement precision and controllability deteriorate
Solution Approach 1:
The patent introduces a fading device as an intermediary component between the measuring device and the relay station. This fading device simulates real-world transmission channel conditions (fading, noise, multipath propagation) while maintaining a controlled laboratory environment. The fading device mediates between the need for realistic field conditions and the need for precise, controllable measurements by providing programmable channel simulations.
Solution Approach 2:
The patent creates a simplified copy of real transmission channel conditions using the fading device. Instead of measuring relay stations in actual field conditions, the system copies essential channel characteristics (fading profiles, noise levels, multipath effects) in a controlled laboratory setting. This allows precise measurement while maintaining measurement realism through accurate channel condition replication.
2Device complexity
If simple signal transmission is used, then measurement setup is simplified, but measurement accuracy deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the fading device with specific fading profiles, noise levels, and channel characteristics before conducting measurements. The first measuring device generates test signals with known characteristics, and the fading device pre-applies simulated channel effects. This preliminary preparation ensures that measurements are conducted under controlled, realistic conditions without complicating the overall measurement setup.
3Adaptability or versatility
If control information is transmitted via relay station, then communication completeness is improved, but measurement purity deteriorates
Solution Approach 1:
The patent extracts the control information transmission function from the relay station measurement process. By separating control plane and user plane traffic, the measurement system can focus exclusively on measuring user data transmission performance through the relay station. Control information is handled separately, allowing pure measurement of user data metrics without contamination from control signaling variations.

AI summary
The invention relates to a measuring device for measuring mobile radio relay stations (21), comprising at least one first measuring apparatus (20) and a receiver (22). The first measuring apparatus (20) produces a first signal and sends the first signal either directly or by means of at least one further apparatus to a relay station (21) to be measured. The receiver (22) receives a second signal derived from the first signal from the relay station (21) to be measured. The first measuring apparatus (20) compares the first signal and at least one signal derived from the second signal.
