PScell Trigger Feedback for Robust Conditional Cell Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conditional primary secondary cell (PScell) addition or change (CPAC) mechanisms lack robustness and accuracy in network device configurations, as they do not effectively utilize trigger information from successful CPAC events to refine execution conditions.
Innovation Solution
A method where a terminal records and sends trigger information of successful CPAC events to a network device, allowing the network device to update and adjust execution condition configurations, thereby enhancing the robustness and accuracy of CPAC processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal directly initiates random access to candidate PScell without recording and reporting trigger information, then the CPAC process is simpler and faster, but the network device cannot accurately update and adjust execution condition configurations, reducing robustness and accuracy
Solution Approach 1:
The terminal records trigger information when CPAC is successful and sends it back to the network device. This feedback mechanism enables the network device to accurately update and adjust execution condition configurations based on actual CPAC outcomes, thereby improving the robustness and accuracy of future CPAC processes.
Solution Approach 2:
The terminal performs preliminary actions by recording trigger information and preparing it for transmission to the network device. This preliminary data collection enables the network device to pre-adjust execution condition configurations before the next CPAC attempt, improving success rates.
2Measurement precision
If the terminal records and sends trigger information to the network device, then the network device can update execution condition configurations with higher accuracy, but the CPAC process becomes more complex and requires additional signaling
Solution Approach 1:
The terminal sends trigger information feedback to the network device, enabling precise updates to execution condition configurations. This feedback loop ensures that the network device has accurate real-time data about CPAC outcomes, improving measurement precision of configuration accuracy.
Solution Approach 2:
The terminal creates a copy of the trigger information and transmits it to the network device. This copying mechanism allows the network device to store and analyze the information for configuration updates without affecting the original CPAC process data.
3Adaptability or versatility
If trigger information is recorded and transmitted for every successful CPAC event, then network optimization is improved, but information loss and transmission overhead increase
Solution Approach 1:
The terminal selectively sends trigger information feedback to the network device based on CPAC success. This targeted feedback approach ensures that only relevant information is transmitted, optimizing network configuration adaptability while minimizing unnecessary information overhead.
Solution Approach 2:
The terminal extracts only the essential trigger information needed for network optimization and transmits it to the network device. This extraction process filters out unnecessary data, reducing transmission overhead while maintaining the core information needed for configuration updates.
