Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limitation of maximum bandwidth in carrier signals hinders the positioning accuracy requirements in 5G mobile communication technology, making it difficult to meet the needs of positioning reference signals in New Radio (NR) systems.
Innovation Solution
A method and apparatus that enable bandwidth aggregation of positioning reference signals across multiple frequency domain resources by requesting and configuring larger bandwidths through on-demand positioning reference signals, improving positioning accuracy and reducing inaccuracies in terminal positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bandwidth aggregation on positioning reference signals is not performed, then the system complexity remains low, but positioning accuracy cannot meet 5G requirements
Solution Approach 1:
The patent divides the positioning reference signal bandwidth into multiple segmented bandwidth parts (BWPs) that can be independently configured and activated. Each BWP represents a segment of the total bandwidth, allowing the system to achieve aggregate bandwidth for positioning while maintaining manageable configuration complexity through modular segmentation.
Solution Approach 2:
The patent implements dynamic bandwidth aggregation where the network can flexibly configure and activate different bandwidth parts based on positioning requirements. The bandwidth aggregation is not fixed but can be dynamically adjusted through RRC signaling, allowing the system to adapt bandwidth resources to meet varying positioning accuracy demands without permanently increasing system complexity.
2Measurement precision
If on-demand positioning reference signals are used, then positioning performance can be improved, but the maximum bandwidth limitation of the carrier still hinders meeting positioning accuracy requirements
Solution Approach 1:
The patent extends the bandwidth dimension by introducing bandwidth aggregation across multiple frequency domain resources. Instead of being limited to a single carrier bandwidth, the system aggregates bandwidth from multiple carriers or frequency resources, effectively adding another dimension to the available bandwidth for positioning reference signals.
Solution Approach 2:
The patent creates a universal bandwidth aggregation mechanism that can be applied to positioning reference signals across multiple carriers and frequency resources. The same aggregation framework serves multiple positioning scenarios and requirements, making the bandwidth resource allocation flexible and multi-functional rather than dedicated to a single carrier.
