Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional driving test methods are used, then basic network coverage can be monitored, but comprehensive sidelink communication quality and traffic information cannot be obtained
Solution Approach 1:
The patent applies multi-functionality by enabling the driving test system to perform multiple measurement types simultaneously - sidelink resource pool congestion measurement, coverage measurement, mobility measurement, synchronization measurement, and QoS measurement. This allows a single measurement system to collect comprehensive sidelink communication information including traffic data and quality metrics, resolving the information loss problem without requiring separate specialized systems for each measurement type.
Solution Approach 2:
The patent segments the driving test information collection into distinct measurement components (congestion measurement, coverage measurement, mobility measurement, synchronization measurement, QoS measurement). Each component focuses on specific aspects of sidelink communication, and the results are integrated to form comprehensive driving test information. This segmentation approach makes the complex measurement system manageable and implementable.
2Measurement precision
If comprehensive sidelink measurement is implemented, then complete traffic and QoS information can be obtained, but measurement and detection difficulty increases
Solution Approach 1:
The patent applies preliminary action by configuring the driving test system with predefined measurement parameters and protocols before actual sidelink communication occurs. The system pre-configures measurement objects, reporting conditions, and information elements needed for accurate QoS and traffic measurement. This preparation ensures that when sidelink communication happens, the system can immediately begin precise measurements without detection difficulty.
Solution Approach 2:
The patent implements feedback mechanisms where measurement results are reported back to the network based on configured reporting conditions. The system continuously monitors sidelink communication quality and feeds back QoS metrics and traffic information to enable ongoing optimization. This feedback loop maintains high measurement precision by allowing continuous adjustment and verification of measurement accuracy.
