Virtual Positioning Measurements for Missing 5G Signal Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly 5G networks, there are challenges in accurately determining the location of user equipment (UE) when certain positioning signal measurements are absent or unavailable due to blockage or communication issues, which affects the precision and completeness of location estimation.
Innovation Solution
The implementation of virtual positioning signal measurements, where a virtual measurement value is provided based on actual positioning signal measurements of the same type, allowing interpolation or extrapolation to fill in missing data points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virtual positioning signal measurements are provided to compensate for missing measurements, then positioning accuracy is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent introduces a virtual measurement value as an intermediary to bridge the gap between actual measurements and expected measurements. This virtual value acts as a mediator that compensates for missing data without requiring complex reconstruction algorithms, thereby improving positioning accuracy while limiting the increase in processing complexity.
Solution Approach 2:
The system performs preliminary determination of whether an expected positioning signal measurement is absent before the positioning calculation process. By identifying missing measurements in advance and providing virtual measurement values proactively, the system avoids the need for complex post-processing and iterative reconstruction methods.
2Measurement precision
If virtual positioning signal measurements are provided to ensure data completeness, then positioning accuracy is improved, but loss of time increases due to additional measurement processing
Solution Approach 1:
The system determines the absence of expected positioning signal measurements and generates virtual measurement values in advance, before the actual positioning calculation is performed. This preliminary action ensures data completeness is achieved without adding time during the critical positioning computation phase.
Solution Approach 2:
The positioning system serves itself by generating virtual measurement values internally when actual measurements are missing, rather than requiring external intervention or complex data fusion from multiple sources. This self-service approach minimizes additional processing time while ensuring data completeness.
3Reliability
If virtual positioning signal measurements are provided, then reliability of positioning data is improved, but device complexity increases due to additional measurement management
Solution Approach 1:
The virtual measurement value serves as an intermediary that simplifies measurement management by providing a straightforward replacement for missing measurements. This intermediary approach improves data reliability without requiring complex measurement fusion algorithms or multiple data source management.
Solution Approach 2:
The system performs preliminary determination of measurement absence and generates virtual values before positioning calculations. This advance preparation ensures reliable data is available when needed, without adding complexity to the actual positioning computation process.

AI summary
A method, for providing a virtual positioning signal measurement, includes: determining that an expected positioning signal measurement is absent from a plurality of actual positioning signal measurements made by a UE; and providing a virtual measurement value, for the expected positioning signal measurement, based on at least one actual positioning signal measurement that is of a same type as the expected positioning signal measurement and that corresponds to at least one positioning signal measured by the UE.
