Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple channel state information report configurations are implemented, then the accuracy of precoding matrix determination is improved, but the device complexity increases
Solution Approach 1:
The patent segments the CSI report configurations into a primary configuration and one or more secondary configurations. The primary configuration contains basic CSI reporting parameters, while secondary configurations contain additional or alternative parameters. This segmentation allows the system to manage multiple configurations in an organized manner, improving CSI reporting accuracy without overwhelming device complexity.
Solution Approach 2:
The patent implements dynamic switching between primary and secondary CSI report configurations based on channel conditions, traffic requirements, and network state. The network can activate or deactivate secondary configurations as needed, allowing the system to adapt to changing conditions and optimize CSI reporting accuracy while managing device complexity through selective activation rather than continuous processing of all configurations.
2Productivity
If multiple channel state information report configurations are implemented, then the resource allocation efficiency is improved, but the computational overhead increases
Solution Approach 1:
The patent applies partial action by implementing secondary CSI report configurations that are not always active but are selectively activated based on specific conditions. Instead of continuously processing all possible configurations, the system performs calculations and comparisons only when secondary configurations become relevant, thereby improving resource allocation efficiency while avoiding excessive computational overhead during normal operation.
Solution Approach 2:
The patent changes parameters such as reporting periodicity, frequency granularity, and spatial resolution between primary and secondary configurations. By adjusting these parameters based on channel conditions and traffic requirements, the system can optimize resource allocation efficiency without requiring full computational processing of all configurations simultaneously, thus managing computational overhead effectively.
3Adaptability or versatility
If dynamic switching between configurations is enabled, then the adaptability to channel conditions is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors the performance of active CSI report configurations and uses this information to make informed decisions about switching between primary and secondary configurations. The feedback loop includes measuring channel quality indicators, evaluating precoding performance, and adjusting configuration activation accordingly, which improves adaptability while managing the complexity of performance measurement through systematic monitoring.
