UE Thermal Measurement Control for Overheat-Aware Radio Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high transmission rates in mobile communication leads to overheating of user equipment (UE), which can cause hardware damage, reduce device lifespan, and result in service interruptions due to thermal protection mechanisms like downtime or automatic restarts, degrading user experience.
Innovation Solution
Implementing thermal measurement configurations to trigger UE temperature measurement during idle or inactive states, using RRC signaling to reduce workload and power consumption in connected states, and adjust radio configurations based on measured temperatures to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high transmission rate is pursued through high operating frequency, then transmission performance is improved, but UE overheating worsens
Solution Approach 1:
The network side performs preliminary temperature assessment by analyzing uplink signal characteristics (received signal strength, signal-to-noise ratio, operating frequency) before the UE actually overheats. This allows proactive identification of UEs at risk of overheating, enabling preventive resource allocation adjustments before thermal damage occurs
Solution Approach 2:
The system establishes a feedback loop where the network side continuously monitors uplink signal characteristics, assesses temperature risk, and adjusts downlink resource allocation accordingly. UEs with high temperature risk receive reduced downlink resources, creating a closed-loop control system that dynamically responds to thermal conditions
2Temperature
If continuous temperature monitoring is implemented in connected state, then temperature control is improved, but power consumption increases
Solution Approach 1:
The network side acts as an intermediary that performs the computationally intensive temperature assessment task. Instead of requiring the UE to continuously monitor and report temperature, the network side infers temperature risk from uplink signal characteristics, significantly reducing UE processing load and power consumption while maintaining effective temperature control
Solution Approach 2:
The patent replaces direct thermal measurement (mechanical/physical sensing) with indirect inference through signal characteristic analysis. By substituting actual temperature sensing with computational assessment based on received signal strength and quality metrics, the system achieves temperature monitoring without the power overhead of continuous sensor operation and data transmission
3Temperature
If downlink resources are reduced for temperature control, then overheating is prevented, but transmission rate decreases
Solution Approach 1:
The system applies differentiated resource allocation strategies to different UEs based on their individual temperature risk profiles. UEs with high temperature risk receive reduced downlink resources, while UEs with low or no risk maintain normal or enhanced resource allocation. This localized, targeted approach ensures temperature control for at-risk devices without unnecessarily limiting transmission rates for thermally stable UEs
