Access Network Transmission Stop for Deactivated Cell Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, the network side device's instruction to activate or deactivate cells or cell groups leads to unnecessary transmission resource waste due to continued communication with deactivated cells or cell groups.
Innovation Solution
Implementing a method where access network devices receive an indication message to stop transmission with deactivated cells or cell groups, thereby avoiding resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network side device instructs the terminal to activate or deactivate cells or cell groups, then the terminal can selectively activate or deactivate target cells or cell groups, but transmission resource waste occurs because the access network device continues to communicate with deactivated cells or cell groups
Solution Approach 1:
The network side device sends a first indication message to the access network device before the terminal actually deactivates the cell or cell group. This preliminary notification allows the access network device to stop transmission in advance, preventing transmission resource waste while maintaining the terminal's cell activation/deactivation adaptability
Solution Approach 2:
The system implements a feedback mechanism where the terminal's cell activation/deactivation status is communicated back to the access network device through the first indication message. This feedback loop ensures the access network device is aware of the terminal's cell state and can adjust transmission accordingly, resolving the contradiction between adaptability and resource efficiency
