Terminal CA MIMO Degradation for Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed data transmission scenarios, terminal devices face increased power consumption and heat issues, leading to reduced user experience due to the need to frequently disconnect and reconnect from networks to manage carrier aggregation (CA) and multiple-input multiple-output (MIMO) functions, which results in high signaling interaction loads and reduced data transmission rates.
Innovation Solution
A method where a terminal device sends a degradation request to a network-side device to degrade CA or MIMO resources, allowing the network-side device to proactively reduce CA component carriers or MIMO service flows based on the terminal's requirements, maintaining network connectivity and reducing interaction load, thus alleviating heat and power consumption issues.

Engineering Contradiction Analysis
1Temperature
If the terminal turns off CA/MIMO function to alleviate heat, then temperature is reduced, but the terminal needs to exit and re-access the network, leading to poor communication experience and high signaling interaction load
Solution Approach 1:
The patent segments the CA/MIMO functions into independently controllable parts. Instead of turning off all CA/MIMO functions at once, the network side device can selectively deactivate specific component carriers or reduce MIMO service flows based on terminal heat status, allowing partial functionality to be maintained while managing temperature.
Solution Approach 2:
The patent implements dynamic adjustment of CA/MIMO functions based on real-time terminal temperature feedback. The network side device receives temperature information from the terminal and dynamically modifies the activation state of component carriers or MIMO service flows, enabling continuous adaptation between heat management and communication performance.
2Temperature
If the terminal turns off CA/MIMO function to alleviate heat, then temperature is reduced, but data transmission rate is significantly reduced
Solution Approach 1:
The patent applies partial action by deactivating only the necessary portion of CA/MIMO functions required for heat management. The network side device can deactivate one or more component carriers or reduce the number of MIMO service flows while maintaining other carriers or flows active, thus partially reducing power consumption without completely sacrificing data transmission rate.
Solution Approach 2:
The patent changes operational parameters of the CA/MIMO system based on temperature conditions. The network side device adjusts parameters such as the number of active component carriers, the number of MIMO service flows, or the modulation and coding schemes according to terminal temperature feedback, enabling adaptive optimization of both thermal performance and data rate.
3Temperature
If the terminal frequently exits and enters the network to manage CA/MIMO functions, then heat is alleviated, but signaling interaction load between terminal and system side increases
Solution Approach 1:
The patent establishes a feedback mechanism where the terminal reports its temperature status to the network side device, which then adjusts CA/MIMO function configuration accordingly. This closed-loop feedback system eliminates the need for frequent network re-access, as the network side device can modify function activation based on received temperature feedback while maintaining the terminal's connected state.
Solution Approach 2:
The network side device acts as an intermediary that manages CA/MIMO function activation/deactivation on behalf of the terminal. Instead of the terminal directly exiting and re-entering the network to change its state, the network side device receives temperature information and controls the function states through existing communication channels, reducing signaling overhead.

AI summary
A high-speed data transmission degradation method, a device, and a system, to implement, in high-speed data transmission and depending on a terminal requirement, resource degradation in which interaction load is low and a terminal remains connected to a network, so as to ensure a data transmission rate of the terminal and improve terminal user experience. The method includes receiving, by a network-side device, a degradation request sent by a terminal that is in a high-speed data transmission mode; obtaining, by the network-side device, a target to-be-degraded resource of the terminal based on the received degradation request; and degrading, by the network-side device, the target to-be-degraded resource.
