Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If reduced capability UEs share the same RMSI configuration with eMBB UEs, then network access complexity is reduced, but access efficiency and success rate deteriorate
Solution Approach 1:
The patent segments the access configuration into separate configurations for reduced capability UEs and eMBB UEs. The base station sends distinct access configuration information to each UE type, allowing optimized parameters for each category rather than forcing all UEs to use a single shared configuration, thereby improving access efficiency while maintaining manageable complexity
Solution Approach 2:
The patent applies local quality by providing tailored access configuration parameters specific to each UE type's characteristics. Reduced capability UEs receive configurations optimized for their limited capabilities, while eMBB UEs receive configurations optimized for high bandwidth operations, ensuring each UE type operates at peak efficiency in its local context
2Productivity
If reduced capability UEs use independent access configuration, then network access efficiency is improved, but network configuration complexity increases
Solution Approach 1:
The patent implements a universal configuration framework where the base station maintains a pool of access configuration parameters that can be selectively applied to different UE types. This multi-functional approach allows the same configuration structure to serve both reduced capability UEs and eMBB UEs with type-specific optimizations, improving access efficiency without proportionally increasing network configuration complexity
Solution Approach 2:
The patent utilizes parameter changes by adjusting specific access configuration parameters based on UE type requirements. Rather than creating entirely separate configuration systems, the network modifies key parameters within a unified configuration framework to accommodate different UE capabilities, achieving efficient access while controlling overall configuration complexity
3Reliability
If system coverage is increased to accommodate reduced capability UEs, then UE complexity is reduced, but wireless resource utilization decreases
Solution Approach 1:
