Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the width of the frequency band for same precoding is determined based only on system bandwidth in LTE system, then the determination method is simple and standardized, but the flexibility is poor and system performance cannot be effectively optimized in different scenario conditions
Solution Approach 1:
The patent applies dynamics by making the frequency band width for same precoding adjustable and adaptable to different scenarios. Instead of a fixed determination method based solely on system bandwidth, the solution enables dynamic configuration through multiple parameters including frequency bandwidth parameters, width values, and width mapping rules that can be selected based on specific scenario requirements, thereby achieving flexibility without excessive complexity
Solution Approach 2:
The patent implements parameter changes by introducing multiple configurable parameters for determining frequency band width. These include frequency bandwidth parameters, width values, and width mapping rules that establish correspondence between system bandwidth and frequency band width. By changing these parameters according to different scenario conditions, the system can optimize performance while maintaining manageable complexity through standardized parameter sets
2Reliability
If multiple parameters are used to determine frequency band width for same precoding, then system performance can be optimized in different scenarios, but the configuration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the frequency band width determination into distinct configurable components: frequency bandwidth parameters, width values, and width mapping rules. Each component serves a specific function and can be independently configured or selected based on scenario requirements. This segmentation allows for systematic optimization of system performance while managing complexity through modular configuration elements
Solution Approach 2:
The patent implements universality by designing a multi-functional precoding configuration system that can adapt to different scenario conditions using the same set of parameters and rules. The width mapping rules establish universal correspondence relationships between system bandwidth and frequency band width that can be applied across various scenarios, enabling performance optimization without requiring scenario-specific complex configurations
