Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If propagation models are updated using real-time measurement data, then measurement precision and reliability are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-collecting and storing measurement data from multiple frequency bands before actual propagation model updates are needed. The measurement data acquisition unit continuously gathers data in advance, and the propagation model update unit prepares updated models based on this pre-collected data, reducing the complexity of real-time processing when updates are actually required.
Solution Approach 2:
The invention introduces a propagation model update unit as an intermediary component that mediates between raw measurement data and the final propagation models. This intermediary processes and transforms the complex measurement data into updated propagation models, simplifying the overall system architecture and making the complexity manageable through modular design.
2Adaptability or versatility
If multiple propagation models are maintained for different frequency bands, then adaptability is improved, but device complexity increases
Solution Approach 1:
The propagation model update unit is designed with multi-functionality to handle multiple frequency bands (mmWave, sub-6 GHz, and other bands) using a unified update mechanism. Instead of maintaining completely separate model management systems for each frequency band, the same update unit processes measurement data across all bands, reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The system manages complexity by changing parameters of existing propagation models rather than creating entirely new models for each frequency band. The update unit adjusts model parameters based on measurement data from different frequency bands, allowing the same base model structure to be adapted across multiple bands through parameter modification rather than structural duplication.
