Measurement Reporting for Preserving Cellular Positioning Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional cellular network positioning, the change in measurement values due to terminal movement or timing advance is smoothed out during reporting, leading to loss of information about the measurement value changes in the reporting periodicity, which affects positioning accuracy.
Innovation Solution
A method where a communication device receives multiple reference signals in a reporting periodicity and reports a subset of measurement values or their changes, allowing the positioning device to determine the measurement value status accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single measurement value is output through filtering in conventional positioning, then the measurement value change is smoothed out, but information about the measurement value change in a reporting periodicity is lost
Solution Approach 1:
The patent segments the measurement reporting by dividing it into multiple measurement results, each corresponding to different reference signals received in different reference signal periodicities. Instead of combining all measurements into a single filtered value, the system reports multiple distinct measurement results that preserve the temporal and spatial variations in measurement values, thus preventing information loss while maintaining stability through selective reporting.
2Loss of information
If multiple measurement results are reported in a single measurement report, then information about measurement value change is retained, but the complexity of the reporting process increases
Solution Approach 1:
The patent implements dynamic measurement reporting where the number and type of measurement results included in each report can vary based on terminal movement status, timing advance changes, and positioning requirements. The system dynamically adjusts the reporting content to include only necessary measurement results, balancing information retention with reporting complexity management through adaptive selection of measurement data.

AI summary
Embodiments of this application provide a measurement reporting method and apparatus, to resolve a problem that information about a measurement quantity change in a reporting periodicity is lost during measurement reporting in a current technology. The method includes: In a measurement reporting periodicity, a first communication device receives N reference signals sent by a second communication device in N reference signal periodicities, and measures the N reference signals to obtain M measurement values. The first communication device reports a measurement report of M measurement results to a positioning device, where N is an integer greater than 1, and M is less than or equal to N. The first communication device may be a terminal, and the second communication device is a base station. Alternatively, the first communication device may be a base station, and the second communication device is a terminal.
