Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in 5G networks, such as smartphones, experience overheating due to increased power consumption and environmental factors, leading to disconnection from the 5G network, resource wastage, and potential hardware damage, which affects user experience and performance.
Innovation Solution
Implementing thermal mitigation guidelines that allow UE to generate temperature thresholds and zones, enabling proactive and reactive actions to maintain or reduce temperature, such as adjusting display brightness, battery saver mode, and network actions, to prevent overheating without disconnecting from the 5G network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user equipment operates in 5G network with increased power consumption, then network connectivity and data access are improved, but temperature increases causing overheating
Solution Approach 1:
The system performs preliminary thermal assessment before allowing 5G operation by evaluating cooling capacity against expected thermal load. Temperature thresholds are pre-established and cooling actions are proactively triggered before critical overheating occurs, preventing the contradiction from manifesting by preparing the thermal management system in advance.
Solution Approach 2:
The system continuously monitors temperature during 5G operation and dynamically adjusts network connectivity parameters based on thermal feedback. When temperature approaches thresholds, the system provides feedback to reduce power consumption or activate cooling, creating a closed-loop control that balances productivity and temperature.
2Temperature
If thermal mitigation actions are taken to reduce temperature, then temperature control is improved, but network disconnection occurs
Solution Approach 1:
Instead of completely disconnecting from 5G when thermal issues arise, the system applies partial mitigation actions such as reducing data rate, activating discontinuous reception, or selectively disabling non-critical functions. This allows temperature control to be achieved while maintaining essential network connectivity and avoiding full disconnection.
Solution Approach 2:
The system establishes temperature thresholds and pre-configures mitigation strategies that prevent network disconnection. By setting appropriate thresholds and having ready-to-execute partial mitigation actions, the system counteracts the tendency toward complete disconnection, maintaining reliability while achieving temperature control.
3Reliability
If continuous operation is maintained to prevent disconnection, then network availability is improved, but resource wastage increases
Solution Approach 1:
The system implements periodic thermal assessments and discontinuous reception modes that allow brief low-power intervals while maintaining network availability. By periodically checking temperature and using discontinuous communication patterns, the system reduces energy consumption and resource wastage while keeping the network connection active and ready for data transfer.
4Temperature
If proactive thermal management is implemented, then temperature prevention is improved, but device complexity increases
Solution Approach 1:
The system performs self-assessment of thermal conditions and automatically selects appropriate mitigation actions without requiring complex external control. The device monitors its own temperature, evaluates cooling capacity, and autonomously adjusts network parameters or activates cooling, reducing the need for complex external thermal management infrastructure.

AI summary
A user equipment may generate one or more temperature thresholds based on thermal mitigation guidelines. The one or more temperature thresholds may define a first temperature zone and a second temperature zone. The user equipment may detect a temperature of the user equipment. The user equipment may identify whether the temperature occurs in the first temperature zone or the second temperature zone. The user equipment may send information to a network device to cause one or more network actions to be performed. The one or more network actions may be configured to maintain or reduce the temperature within the first temperature zone or to reduce the temperature to cause the temperature to switch from the second temperature zone to the first temperature zone.
