Conditional PSCell Addition Change Reporting in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems face challenges in optimizing conditional primary secondary cell (PSCell) addition and change operations, which are crucial for enhancing data rates and network performance, especially in scenarios requiring dual connectivity.
Innovation Solution
A method and apparatus for reporting successful conditional PSCell addition and change (CPAC) operations, where user equipment (UE) receives configuration information from a base station, performs PSCell changes based on specified conditions, and transmits a successful PSCell change report (SPR) when conditions are met, allowing the base station to recognize and optimize parameter configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional PSCell addition and change operations are implemented to enhance data rates and network performance, then network performance is improved, but the complexity of the system increases
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports successful CPAC operations to the base station. This feedback loop allows the base station to recognize when CPAC has been successfully executed and use this information to optimize future parameter configurations, thereby improving network performance while managing system complexity through informed control.
Solution Approach 2:
The patent focuses on optimizing parameter configurations for CPAC operations. By systematically adjusting and reporting on parameter settings (such as timing, conditions, and configuration parameters), the system achieves improved network performance while maintaining manageable complexity through structured parameter optimization rather than uncontrolled system complexity.
2Reliability
If the UE reports successful CPAC operations to the base station, then the base station can optimize parameter configurations, but additional signaling overhead is introduced
Solution Approach 1:
The reporting mechanism constitutes a feedback channel that conveys CPAC success status from UE to base station. This targeted feedback provides essential information for parameter optimization without requiring continuous or excessive signaling, as it only transmits when CPAC operations are successfully completed.
Solution Approach 2:
The UE autonomously determines when to report based on whether CPAC operations were successful. This self-service approach allows the UE to control the reporting behavior, initiating reports only when necessary (upon successful completion) rather than continuously, thereby reducing signaling overhead while maintaining effective parameter configuration optimization.
