User Equipment Overheating Protection via Base Station Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed wireless transmission modes in LTE systems can lead to user equipment (UE) overheating, causing transmission interruptions and requiring temperature control measures that may degrade user experience, such as detaching and reattaching radio link configurations, which can further interrupt data transmission.
Innovation Solution
A method where the user equipment sends a signaling request for a cooling configuration to the base station, starts a timer, and detects its temperature upon timeout, indicating its state to the base station, allowing the base station to reduce the UE configuration and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed wireless transmission modes are used to meet users' requirements for high data transmission rate, then productivity is improved, but user equipment overheating occurs causing transmission interruptions
Solution Approach 1:
The patent implements a feedback mechanism where the UE monitors its own temperature and reports overheating status to the base station. The base station receives this feedback and adjusts the radio link configuration accordingly, reducing transmission parameters when overheating is detected and restoring them when cooling occurs, thus maintaining transmission continuity while managing thermal conditions
Solution Approach 2:
The patent dynamically adjusts the radio link configuration based on real-time temperature conditions. The base station modifies transmission parameters such as modulation order, coding rate, and resource allocation dynamically in response to UE overheating status, allowing the system to adapt between high-performance and thermal-safe operating states
2Temperature
If UE performs temperature control by detaching and reattaching radio link configuration, then overheating is avoided, but transaction data transmission is interrupted degrading user experience
Solution Approach 1:
The patent enables preliminary temperature monitoring and proactive overheating notification before critical thermal conditions occur. The UE continuously monitors temperature and can alert the base station in advance, allowing the base station to pre-adjust configuration parameters before overheating forces a transmission interruption, thus preventing the need for detaching and reattaching
Solution Approach 2:
The patent introduces signaling communication between UE and base station as an intermediary mechanism for temperature management. Instead of direct UE configuration changes that cause interruption, the UE sends overheating indications to the base station, which then mediates the configuration adjustment, maintaining continuous transmission while managing thermal conditions

AI summary
The present application relates to a method and apparatus for protecting user equipment, user equipment and a base station. The method for protecting the user equipment includes: starting a timer of a first preset time period after first signaling for requesting for a cooling configuration is sent to a base station; detecting an equipment temperature of the user equipment at a time when the timer times out; and indicating to the base station a user equipment state indicated by the equipment temperature. The technical solution according to the present disclosure may solve the problem of user equipment (UE) overheating by reducing the UE configuration by means of a base station, and when the UE no longer overheats, the base station configures a high radio link configuration for the UE in time to ensure the data transmission rate of the UE.
