Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in secondary cell activation due to long delays and resource consumption caused by unnecessary delays in activating secondary cells, leading to potential data loss and increased errors.
Innovation Solution
A method and apparatus for configuring secondary cell activation reference signals using a trigger state indication, allowing for efficient reception of SCell activation signals based on a configuration, reducing delays and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional secondary cell activation methods are used, then cell activation can be achieved, but long delays and resource consumption occur
Solution Approach 1:
The patent applies preliminary action by pre-configuring reference signal resources and trigger states before SCell activation is needed. The network device pre-sets multiple reference signal resources with different timing configurations, and the UE prepares trigger state indicators in advance. When activation is required, the network simply triggers the pre-configured resources, eliminating the need for time-consuming resource negotiation and configuration during the activation process itself.
2Reliability
If traditional secondary cell activation methods are used, then cell activation can be achieved, but resource consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring reference signal resources and trigger states before SCell activation is needed. The network device pre-sets multiple reference signal resources with different timing configurations, and the UE prepares trigger state indicators in advance. When activation is required, the network simply triggers the pre-configured resources, eliminating the need for time-consuming resource negotiation and configuration during the activation process itself.
Solution Approach 2:
The patent applies segmentation by dividing the SCell activation process into distinct phases: pre-configuration phase where reference signal resources are prepared, triggering phase where activation is initiated using pre-configured trigger states, and execution phase where the actual activation occurs. This segmentation allows each phase to be optimized independently, with the triggering phase being particularly efficient as it uses pre-prepared configurations rather than negotiating resources in real-time.
