Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE systems, high-speed wireless transmission modes can cause User Equipment (UE) overheating, leading to service data transmission interruptions and device restarts, with existing solutions like detachment and re-attachment of UE interrupting data transmission and providing a poor user experience.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed wireless transmission modes are used to meet user demand for high data transmission speed, then data transmission speed is improved, but UE temperature increases causing overheating
Solution Approach 1:
The patent implements dynamic adjustment of radio link configuration parameters (such as modulation order, coding rate, MIMO layers) based on real-time temperature monitoring. When overheating is detected, the system dynamically transitions from high-speed transmission modes to lower-power modes, and vice versa when temperature is acceptable, creating a flexible adaptive system that balances speed and thermal management
Solution Approach 2:
The system changes physical parameters of the transmission configuration (modulation scheme, bandwidth, power level) in response to temperature conditions. By modifying these transmission parameters dynamically, the system can reduce power consumption and heat generation while maintaining acceptable data transmission performance
2Temperature
If detachment and re-attachment of UE is performed to control temperature and avoid overheating, then UE temperature is reduced, but data transmission is interrupted
Solution Approach 1:
The system performs preliminary temperature monitoring and proactive configuration adjustment before critical overheating occurs. By detecting temperature trends early and preemptively adjusting radio link parameters or triggering cooling actions, the system prevents overheating-related failures without needing to interrupt service through detachment and re-attachment
Solution Approach 2:
The patent implements a closed-loop feedback mechanism where temperature is continuously monitored and this information feeds back to adjust transmission parameters in real-time. This feedback control enables the system to maintain temperature within acceptable ranges while keeping data transmission continuous, eliminating the need for disruptive detachment operations
3Temperature
If frequent signaling is sent to request cooling configuration, then cooling response is achieved, but signaling burden increases
Solution Approach 1:
Instead of continuous or event-driven frequent signaling, the system implements periodic temperature monitoring and configuration reporting at predetermined intervals. This periodic approach reduces signaling frequency while still achieving effective cooling management, as the system only needs to check and report at regular intervals rather than constantly
Solution Approach 2:
The patent integrates temperature monitoring and cooling configuration requests into existing multi-purpose signaling mechanisms and maintenance procedures. By combining thermal management functions with routine system operations, the patent reduces additional signaling overhead while achieving effective cooling control

AI summary
The present disclosure relates to an overheating protection method and device of user equipment, the user equipment and a base station. The overheating protection method of the user equipment comprises: when it is determined that the user equipment is overheated as a result of overhigh wireless link configuration, transmitting to the base station a first signaling requesting a cooling configuration and starting a timer with a preset duration; detecting the temperature of the user equipment in the case of timeout of the timer; and performing an operation corresponding to the detection result. According to the technical scheme of the present disclosure, cooling can be achieved by transmitting the signaling requesting the cooling configuration to the base station when the user equipment (UE) is overheated; and the problem of a heavy signaling burden caused by frequent transmission of signalings at any time can be avoided.
