User Equipment Overheating Adjustment via Network Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for addressing overheating in terminals during high-speed data transmission, such as carrier aggregation and MIMO, either result in poor user experience due to network disconnection or violate 3GPP standards by allowing terminals to proactively deactivate secondary serving cells, leading to network compatibility issues and ineffective heat alleviation.
Innovation Solution
A method where user equipment detects overheating and reports to a network device, which instructs the equipment to adjust radio resource configurations, such as deactivating or activating secondary serving cells, without disconnecting from the network, ensuring compliance with 3GPP standards and maintaining network compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the terminal exits the network and re-registers to adjust carrier aggregation or MIMO configuration, then the overheating problem is alleviated, but user experience deteriorates due to network disconnection
Solution Approach 1:
The patent introduces an intermediary mechanism where the terminal sends an overheating indication message to the network device, which then sends back a configuration adjustment instruction. This mediator approach allows the terminal to adjust its carrier aggregation or MIMO configuration without needing to exit the network, thus resolving the contradiction between temperature reduction and maintaining continuous network connectivity for good user experience
Solution Approach 2:
The patent implements preliminary action by having the terminal proactively send an overheating indication message before completely failing or disconnecting. The network device receives this indication and proactively sends configuration adjustment instructions to reduce the terminal's load, preventing the need for network disconnection while still achieving temperature reduction
2Temperature
If the terminal proactively deactivates secondary serving cells to reduce temperature, then heat alleviation is achieved, but 3GPP standard compliance is violated leading to network compatibility issues
Solution Approach 1:
The patent implements a feedback mechanism where the terminal sends an overheating indication message to the network device, and the network device responds with configuration adjustment instructions. This closed-loop feedback ensures that the terminal's configuration changes are coordinated with the network, maintaining 3GPP standard compliance and network compatibility while still achieving temperature reduction
Solution Approach 2:
The network device acts as an intermediary that mediates between the terminal's need to reduce temperature and the network's requirement for standard compliance. The network device receives the overheating indication and sends back standardized configuration adjustment instructions, ensuring that the terminal's configuration changes are properly coordinated and compliant with 3GPP standards

AI summary
A radio resource configuration adjustment method includes detecting, by user equipment, an overheating problem or that the overheating problem is alleviated, and sending, by the user equipment, a first message to a network device, where the first message is used to notify the network device that the overheating problem occurs in the user equipment or the overheating problem is alleviated; receiving, by the user equipment, a response message sent by the network device, where the response message is used to instruct the user equipment to perform one of the following operations, and the operations include deactivating a secondary serving cell, activating a secondary serving cell, releasing a secondary serving cell, and adding a secondary serving cell; and deactivating, by the user equipment, a secondary serving cell, or activating a secondary serving cell, or releasing a secondary serving cell, or adding a secondary serving cell according to the response message.
