Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If AI/ML models are introduced into CSI reporting scenarios, then CSI compression and encoding capability is improved, but clarity and consistency in determining input information type deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (indication information) that mediates between the AI/ML model and the input information. This indication information explicitly specifies the type of input information (e.g., channel information, precoding matrix information, rank information) that should be fed into the CSI compression and encoding model, thereby resolving the ambiguity while maintaining the advanced compression capability.
Solution Approach 2:
The patent segments the input information determination process into distinct types (channel information, precoding matrix information, rank information) and uses indication information to specify which segment should be used. This segmentation approach maintains clarity by clearly defining what goes into the AI/ML model while preserving the improved compression capability.
2Device complexity
If the type of input information for CSI compression and encoding model is not clearly determined, then device complexity is reduced, but accuracy and reliability of CSI encoding and decoding deteriorates
Solution Approach 1:
The indication information acts as an intermediary that carries explicit type information without adding significant complexity to the devices. The indication information simply specifies the input type (channel information, precoding matrix information, or rank information), maintaining device simplicity while ensuring accurate and reliable CSI encoding and decoding through clear type determination.
3Reliability
If explicit indication information is used to specify input information type, then accuracy and reliability of CSI encoding and decoding is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent uses parameter changes in the indication information to specify different input information types. By encoding the input type as a parameter (e.g., indicating channel information, precoding matrix information, or rank information), the system achieves high reliability in CSI encoding and decoding while keeping the complexity manageable through efficient parameter representation.
