Secondary Cell Group Activation and Deactivation for Radio Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to optimize resource utilization by maintaining unnecessary Secondary Cell Groups (SCGs) even when there is less downlink or uplink data, leading to wastage of radio resources and reduced efficiency.
Innovation Solution
The method involves instructing the terminal device to deactivate the SCG through first indication information when the data rate requirement is reduced, optimizing resource utilization by saving radio resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the SCG is configured to ensure high data transmission rates, then the data transmission capability is improved, but the radio resource utilization efficiency deteriorates when data rate requirements are reduced
Solution Approach 1:
The patent implements dynamic SCG configuration by introducing activation and deactivation mechanisms. The network device can dynamically adjust the SCG configuration state based on real-time data rate requirements, switching between active and inactive states to optimize both transmission capability and resource efficiency.
Solution Approach 2:
The patent changes the configuration parameter state of the SCG from static to dynamic. By introducing activation indication information and deactivation indication information, the system can change the SCG configuration parameter between different states (activated/inactivated) to adapt to varying data rate requirements, resolving the contradiction between maintaining high transmission rates and improving resource efficiency.
2Productivity
If the SCG is continuously activated to meet peak data rate requirements, then the data transmission capability is improved, but the resource waste increases during low data rate periods
Solution Approach 1:
The patent implements periodic activation and deactivation of the SCG based on data rate requirements. Instead of continuous activation, the system periodically adjusts the SCG state - activating when high data rates are needed and deactivating during low data rate periods, thereby eliminating resource waste while maintaining transmission capability when required.
Solution Approach 2:
The system automatically adjusts SCG activation status based on monitored data rate requirements without manual intervention. The network device self-manages the SCG configuration by detecting when activation or deactivation is needed and executing the appropriate actions, optimizing resource usage while ensuring transmission capability is available when required.
3Adaptability or versatility
If the SCG configuration is maintained to support dual connection scenarios, then the system flexibility is improved, but the resource utilization efficiency deteriorates when the SCG is not needed
Solution Approach 1:
The patent makes the SCG configuration universal by implementing a standardized activation and deactivation mechanism that can be applied in various scenarios - both when dual connection is needed and when it is not. This multi-functional approach allows the same configuration framework to adapt to different operational requirements, maintaining flexibility while improving resource efficiency.

AI summary
Provided are a wireless communication method, a network node, and a device. The method comprises: a first node sending first indication information to a terminal device, with the first indication information being used for indicating the deactivation of a secondary cell group (SCG). First indication information is used to instruct a terminal device to deactivate an SCG, such that when the rate requirement of the terminal device is reduced, not only can the requirements of a user be met, but wireless resources of the terminal device can also be conserved, and the resource utilization efficiency is improved.
