Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high data rate techniques like millimeter wave bands and massive MIMO are employed, then data rate is improved, but thermal issues worsen causing overheating in user equipment
Solution Approach 1:
The system dynamically adjusts radio resource allocation and processing continuity based on real-time thermal conditions. The network entity receives thermal information from the user equipment and modifies scheduling decisions to maintain data rates within acceptable ranges while preventing overheating, creating a dynamic balance between performance and thermal management
Solution Approach 2:
The invention changes operational parameters such as radio resource allocation patterns and processing continuity based on thermal state. By modifying these parameters in response to thermal conditions, the system can reduce heat generation while maintaining acceptable data rate performance
2Productivity
If continuous processing of radio resources is maintained to ensure high data rate, then productivity is improved, but temperature increases leading to overheating
Solution Approach 1:
The system implements periodic thermal monitoring and adjusts radio resource processing accordingly. By introducing periodic interruptions or reducing processing continuity during thermal stress periods, the system allows thermal management while maintaining overall productivity through selective continuous processing when conditions permit
3Temperature
If thermal management measures are implemented to reduce overheating, then temperature is controlled, but data rate and productivity may be reduced
Solution Approach 1:
The system employs feedback mechanisms where thermal information is continuously monitored and reported to the network entity. Based on this feedback, the network dynamically adjusts radio resource allocation to maintain data rates while preventing overheating, ensuring that thermal management actions are proportional to actual thermal conditions and do not unnecessarily reduce productivity
