Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AI/ML-based CSI report configurations are implemented to improve measurement precision and system intelligence, then CSI report accuracy and automation are improved, but processor overheating occurs due to massive computing requirements
Solution Approach 1:
The patent introduces overheating assistance information that enables the network side to adjust CSI report configuration parameters dynamically. When overheating is detected, the network can modify parameters such as reporting frequency, number of reports, or AI/ML processing intensity, thereby reducing computational load and processor temperature while maintaining acceptable CSI accuracy through adaptive parameter optimization
Solution Approach 2:
The system transitions from static CSI report configurations to dynamic configurations that adapt to thermal conditions. The overheating assistance information mechanism allows real-time adjustment of CSI reporting behavior based on processor temperature status, enabling the system to flexibly balance between measurement precision and thermal management requirements
2Measurement precision
If the number of CSI report configurations is increased to improve system intelligence and measurement accuracy, then CSI reporting precision is improved, but device complexity increases leading to overheating
Solution Approach 1:
The patent enables dynamic adjustment of CSI report configuration parameters through overheating assistance information. The network can modify the number of CSI reports, reporting frequency, and AI/ML processing intensity based on thermal conditions, thereby reducing processing complexity and device temperature while maintaining acceptable measurement precision through adaptive optimization
Solution Approach 2:
The system implements conditional CSI reporting where full AI/ML-based reporting is performed only when thermal conditions permit. When overheating occurs, the system reduces to partial reporting or traditional non-AI methods, avoiding excessive processing complexity while maintaining sufficient measurement accuracy for normal operation through selective application of computational resources
3Temperature
If conventional overheating protection methods are applied to reduce carriers or coding layers, then processor temperature is reduced, but throughput rate and communication efficiency deteriorate
Solution Approach 1:
The patent applies differentiated quality management to different system components during thermal conditions. Instead of uniformly reducing all communication parameters, the system selectively adjusts only CSI report-related processing intensity and configuration complexity while maintaining other throughput-determining parameters such as modulation order, coding rate, and carrier aggregation configurations, thereby achieving thermal management with minimal impact on overall throughput
Solution Approach 2:
The system dynamically adjusts CSI reporting behavior based on thermal status rather than applying static throughput reduction. The overheating assistance information mechanism allows real-time modification of CSI processing load without affecting other communication parameters, enabling the system to maintain high throughput through adaptive thermal management that preserves communication efficiency while controlling processor temperature
