Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If AI technologies are used for CSI feedback to reduce overhead, then overhead reduction is achieved, but concrete implementation details are not yet defined
Solution Approach 1:
The patent segments the CSI feedback process into distinct functional blocks: input information reception, encoder processing, and CSI report generation. This segmentation allows AI technologies to be applied specifically to the encoding stage without requiring complete redefinition of the entire feedback mechanism, thereby reducing overhead while managing implementation complexity through modular design.
Solution Approach 2:
The encoder in the patent serves multiple functions: it processes input information related to channel state, applies AI-based compression, and generates the CSI report. This multi-functionality allows the system to achieve overhead reduction through AI technologies without requiring separate dedicated components for each function, thus reducing overall system complexity while maintaining effectiveness.
2Measurement precision
If AI technologies are used for CSI feedback to improve accuracy, then channel estimation accuracy is improved, but resource utilization efficiency is reduced
Solution Approach 1:
The patent changes the parameters of the encoder processing to optimize the balance between accuracy and resource utilization. By adjusting encoding parameters and AI model complexity, the system can achieve improved channel estimation accuracy while controlling resource consumption, resolving the contradiction between measurement precision and productivity.
3Measurement precision
If detailed input information is provided to the encoder, then CSI report accuracy is improved, but overhead increases
Solution Approach 1:
The patent extracts only the essential input information related to channel state that is most critical for accurate CSI reporting, rather than processing all available data. This selective extraction allows the system to maintain high CSI report accuracy while minimizing the overhead associated with transmitting and processing detailed input information through the encoder.
