Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive channel state information reporting is performed to ensure accurate channel measurement and network optimization, then measurement precision and network efficiency are improved, but energy consumption and processing burden increase
Solution Approach 1:
The patent divides the comprehensive channel state information into multiple sub-configuration types (first sub-configuration, second sub-configuration, third sub-configuration). The UE selectively reports only the necessary sub-configuration based on network conditions, rather than reporting all channel state information comprehensively. This segmentation enables energy-saving operation while maintaining sufficient measurement precision for network optimization.
Solution Approach 2:
The patent implements partial action by requiring the UE to report only a subset of channel state information (specific sub-configurations) rather than all available channel state information. The base station receives and processes only the necessary partial information to make scheduling decisions, reducing UE processing burden and energy consumption while maintaining adequate network optimization capability.
2Productivity
If frequent CSI reporting is performed to optimize resource allocation and network efficiency, then productivity and network response speed are improved, but energy consumption and signaling overhead increase
Solution Approach 1:
The patent implements periodic action through semi-persistent scheduling where the base station periodically activates CSI reporting based on network conditions. Rather than continuous frequent reporting, the system uses periodic activation with configurable durations and intervals. This reduces overall energy consumption while maintaining adequate resource allocation efficiency during active periods.
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms where the base station can modify CSI reporting configurations in real-time based on network conditions. The system dynamically adjusts reporting frequency, duration, and triggering conditions to balance resource allocation efficiency with energy consumption, allowing flexible adaptation to varying network demands.
3Manufacturing precision
If detailed sub-configuration information is reported to enable precise network control and optimization, then measurement precision and control accuracy are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent segments the detailed channel state information into distinct sub-configuration categories (first, second, third sub-configurations), each serving specific network control purposes. This segmentation allows the UE to organize and report detailed information in a structured manner, maintaining network control precision while simplifying the processing complexity through clear information categorization.
Solution Approach 2:
The patent applies local quality by providing different levels of detail for different sub-configurations based on their specific requirements. Not all sub-configurations require the same level of detail, so the system tailors the reporting granularity to local needs, reducing overall processing complexity while maintaining necessary precision for critical control functions.
