Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UE historical information records only include primary cell-related information, which is not sufficient for communication scenarios with new properties such as Multi/Dual-Connectivity and carrier aggregation, limiting the ability of networks to determine UE position and configure optimal cell-level/beam-level parameters.
Innovation Solution
The method involves recording and reporting UE information that includes secondary node information, secondary cell information, beam information, cell-level measurement result information, beam-level measurement result information, and historical information of the UE in an inactive state, enabling the expansion of UE historical records to accommodate new communication scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE historical information records only include primary cell-related information, then the recording scheme is simple and easy to implement, but it is not sufficient for communication scenarios with new properties such as Multi/Dual-Connectivity and carrier aggregation
Solution Approach 1:
The UE information recording is segmented into multiple independent components: primary cell information, secondary cell information, beam information, and measurement result information. Each component can be independently recorded, managed, and reported, allowing the system to adapt to different communication scenarios without requiring complete redesign of the recording structure.
Solution Approach 2:
The patent extends the traditional single-dimension primary cell recording by adding multiple new dimensions: secondary cell dimension, beam dimension, and measurement result dimension. This multi-dimensional information structure enables comprehensive tracking of UE behavior in complex scenarios like Multi-Connectivity and carrier aggregation, while maintaining organized and manageable data through systematic categorization.
2Loss of information
If UE information is expanded to include secondary node information, secondary cell information, beam information, and measurement results, then networks can determine UE position and configure optimal parameters, but the quantity of information to be recorded and reported increases
Solution Approach 1:
The patent extracts and separates different types of UE information into distinct categories: primary cell information, secondary cell information, beam information, and measurement result information. This extraction allows the network to selectively request and process only the specific information types needed for particular scenarios, rather than handling all information uniformly, thus managing information quantity while maintaining completeness.
Solution Approach 2:
The UE records comprehensive information including all secondary cells, beams, and measurement results, but the network can selectively utilize only the partial information necessary for specific tasks such as UE positioning or parameter configuration. This approach ensures information completeness is maintained while allowing flexible, demand-driven information processing that manages the practical quantity of handled data.
3Reliability
If the UE records detailed information about secondary cells and beams, then the network can optimize configuration for complex scenarios, but the processing complexity on both UE and network side increases
Solution Approach 1:
The UE performs preliminary recording and organization of detailed secondary cell and beam information along with measurement results before network requests. This preliminary action prepares the information in advance in a structured format, reducing the processing burden during actual network interactions and enabling accurate configuration decisions without increasing real-time processing complexity.
Solution Approach 2:
The recorded detailed information about secondary cells, beams, and measurement results provides feedback to the network, enabling the network to make accurate configuration decisions. The feedback mechanism allows the network to optimize configurations based on actual UE observations and measurements, improving reliability while managing complexity through automated decision-making algorithms that process the structured feedback information.
