Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single channel state information report configuration is used, then the device complexity is reduced, but the measurement precision and adaptability of CSI reporting deteriorate
Solution Approach 1:
The patent divides the single CSI report configuration into multiple configurations (first and second CSI report configurations), each with different resolution levels. This segmentation allows the system to maintain multiple CSI reporting options without requiring a complete redesign of the CSI management architecture, thus improving measurement precision while controlling device complexity through modular configuration management.
Solution Approach 2:
The patent introduces dynamic switching between different CSI report configurations based on channel conditions and performance requirements. The network can dynamically select which CSI report configuration to use, enabling the system to adapt to varying measurement precision needs while maintaining manageable device complexity through flexible configuration selection rather than fixed single-configuration designs.
2Measurement precision
If high-resolution CSI reporting is always used, then the measurement precision is improved, but the loss of energy and productivity decreases due to increased processing overhead
Solution Approach 1:
The patent enables dynamic adjustment of CSI reporting resolution by switching between different CSI report configurations based on channel conditions and network requirements. When high precision is needed, the system uses high-resolution configurations; when energy efficiency is prioritized, lower-resolution configurations are selected, thus optimizing the trade-off between measurement precision and energy consumption.
Solution Approach 2:
The patent changes the resolution parameter of CSI reporting by selecting different configurations with varying resolution levels. This parameter change allows the system to adapt CSI reporting precision to actual needs, avoiding unnecessary high-resolution reporting when it is not required, thereby reducing processing energy consumption while maintaining adequate measurement precision when needed.
3Adaptability or versatility
If multiple channel state information report configurations are maintained, then the adaptability is improved, but the device complexity and difficulty of operation increases
Solution Approach 1:
The patent segments multiple CSI report configurations into distinct, well-defined structures (first and second configurations with different resolution characteristics). This segmentation provides clarity in managing multiple configurations, making it easier to operate and select appropriate configurations rather than dealing with an undifferentiated set of complex options.
Solution Approach 2:
The patent designs the multiple CSI report configurations to serve universal purposes across different operating conditions. Each configuration is designed with a specific resolution level that can be universally applied in appropriate scenarios, providing a systematic approach to configuration selection that simplifies operation while maintaining high adaptability to various channel conditions and network requirements.
4Productivity
If dynamic switching between CSI configurations is implemented, then the productivity and communication performance is improved, but the device complexity and loss of time for configuration management increases
Solution Approach 1:
The patent prepares multiple CSI report configurations in advance, with each configuration pre-defined for specific resolution requirements and channel conditions. This preliminary preparation eliminates the need for complex real-time configuration creation during switching, reducing the time loss associated with configuration management while enabling efficient dynamic switching to optimize productivity and resource allocation.
Solution Approach 2:
The patent implements dynamic switching between pre-prepared CSI configurations based on real-time channel conditions and network state. This dynamic approach allows the system to quickly adapt to changing conditions and optimize resource allocation without requiring complex real-time configuration synthesis, thus improving productivity while minimizing the time loss for configuration management through efficient pre-prepared configuration selection.
