Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cell measurement information is collected and reported in next-generation mobile communication systems, then network optimization and handover performance are improved, but system complexity and processing overhead increase
Solution Approach 1:
The measurement collection process is segmented into different types of measurements (first cell measurement information and second cell measurement information) with distinct collection conditions and reporting mechanisms, allowing the system to manage complexity through structured categorization while maintaining comprehensive measurement capabilities for network optimization
Solution Approach 2:
The system performs preliminary actions by collecting and storing measurement information in advance according to configured conditions, enabling efficient handover decisions and network optimization without real-time processing complexity, thus improving reliability while managing system complexity
2Productivity
If V2X data packets are transmitted using sidelink radio bearer, then communication efficiency and service support are improved, but data integrity and security requirements increase
Solution Approach 1:
The system implements integrity protection mechanisms that provide feedback on data authenticity and completeness for V2X packets, ensuring that communication efficiency is maintained while data integrity requirements are met through verification protocols in the PDCP layer
Solution Approach 2:
The system changes the integrity protection parameter from traditional packet-level protection to per-packet integrity protection with configurable protection levels, allowing the system to adjust security measures based on the specific V2X service requirements while maintaining high communication efficiency
