Multi-Frequency-Layer Positioning With Unified Resource Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in achieving accurate positioning due to limited bandwidth and complexity in processing multiple frequency layers, particularly in indoor scenarios where GPS signals are weak, and there is a need for improved methods to aggregate positioning reference signals across multiple frequency layers.
Innovation Solution
The system aggregates positioning reference signals across multiple frequency layers by using a single signaling mechanism to schedule multiple resource sets with the same resource identifiers, enabling UE capability reporting for both single and aggregated frequency layer processing, and optimizing bandwidth and processing durations to enhance positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple frequency layers are processed for positioning measurements, then positioning accuracy is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent combines multiple frequency layer resources into a single aggregated resource set with unified resource identifiers. This merging approach allows the UE to process multiple frequency layers simultaneously while reducing signaling overhead and processing complexity, as the network uses a single signaling mechanism to schedule resources across multiple frequency layers rather than separate signaling for each layer
Solution Approach 2:
The patent creates a universal resource identification scheme where resource identifiers can represent multiple frequency layer resources. This multi-functional identifier system allows the same resource ID to point to resources across different frequency layers, enabling the UE to handle aggregated resources from multiple frequency layers through a unified processing framework
2Measurement precision
If multiple frequency layers are aggregated for positioning, then positioning accuracy in indoor environments is improved, but bandwidth and resource management complexity increase
Solution Approach 1:
The patent merges resource management across multiple frequency layers by creating aggregated resource sets with unified identifiers. This consolidation simplifies resource management by allowing the network to schedule and the UE to process resources from multiple frequency layers through a single management framework, reducing the complexity of tracking and managing resources across different frequency layers
3Adaptability or versatility
If separate signaling is used for each frequency layer, then resource scheduling flexibility is maintained, but signaling overhead increases
Solution Approach 1:
The patent merges multiple separate signaling mechanisms into a single unified signaling approach. By using one signaling message to schedule resources across multiple frequency layers simultaneously, the system reduces signaling overhead while maintaining scheduling flexibility, as the unified signaling can still specify different resource allocations for each frequency layer within the same message
