Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for neighboring cell measurement in mobile communication networks face challenges in effectively configuring measurement gaps to support both SSB-based and CSI-RS-based mobility measurements, leading to suboptimal performance due to overlapping or non-overlapping resource durations.
Innovation Solution
Configuring a measurement gap combination that includes a maximum value of SSB-based and CSI-RS-based measurement gap lengths and repetition periods to ensure simultaneous support for both types of measurements, allowing the UE to perform handover based on optimized signal quality assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single measurement gap configuration is used for both SSB-based and CSI-RS-based measurements, then the configuration simplicity is improved, but the measurement accuracy deteriorates due to overlapping or non-overlapping resource durations
Solution Approach 1:
The patent divides the measurement gap configuration into separate configurations for SSB-based measurements and CSI-RS-based measurements. The network device configures first measurement gaps specifically for SSB resources and second measurement gaps specifically for CSI-RS resources, allowing each type of measurement to have optimized timing without interference from the other.
Solution Approach 2:
The patent implements dynamic measurement gap configuration where the network device can independently adjust the timing and duration of first measurement gaps and second measurement gaps based on actual network conditions, SSB resource locations, and CSI-RS resource locations, enabling adaptive optimization of measurement accuracy.
2Adaptability or versatility
If measurement gaps are configured to cover both SSB and CSI-RS resources, then the versatility of the measurement configuration is improved, but the measurement timing accuracy deteriorates due to resource overlap or gaps
Solution Approach 1:
The patent segments the measurement gap configuration into distinct first measurement gaps for SSB resources and second measurement gaps for CSI-RS resources. This segmentation ensures that each measurement type has dedicated timing configuration, eliminating the resource overlap and timing gaps that occur when using a single unified measurement gap configuration.
Solution Approach 2:
The patent applies local quality optimization by configuring measurement gaps with specific timing parameters tailored to each measurement type's requirements. The first measurement gaps are optimized for SSB resource timing while the second measurement gaps are optimized for CSI-RS resource timing, ensuring each measurement operates under ideal local conditions.
