UE Positioning Model Validation Using Mismatch Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately determining the position of user equipment (UE) due to variations in radio frequency fingerprint positioning (RFFP) measurements, leading to inconsistencies and uncertainties in positioning models.
Innovation Solution
The method involves obtaining multiple sets of position estimates using different positioning techniques and models, including radio frequency fingerprint positioning (RFFP), and comparing these estimates to generate mismatch or error reports to assess the validity and uncertainty of the positioning models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single positioning model is used for UE positioning, then the positioning process is simple and fast, but the accuracy and reliability are reduced due to variations in RFFP measurements
Solution Approach 1:
The patent combines multiple positioning models (RFFP-based model and non-RFFP-based model) to generate position estimates. By merging the results from different positioning approaches, the system achieves more accurate and reliable positioning while compensating for the limitations of individual models, particularly addressing the variations in RFFP measurements.
Solution Approach 2:
The patent implements a feedback mechanism where mismatch reports are generated by comparing position estimates from different positioning models. These mismatch reports provide feedback to assess the validity of the positioning model, allowing the system to identify and correct inconsistencies, thereby improving positioning accuracy over time.
2Adaptability or versatility
If RFFP measurements are used for positioning, then positioning capability is enhanced, but inconsistencies and uncertainties in positioning models increase
Solution Approach 1:
The patent introduces an intermediary assessment mechanism (mismatch report generation and model validity assessment) that mediates between the RFFP measurements and the final position estimate. This intermediary process compares results from multiple positioning models to identify inconsistencies, thereby maintaining the enhanced positioning capability of RFFP while reducing the uncertainties and inconsistencies in the positioning model.
3Measurement precision
If multiple positioning models are compared to assess validity, then positioning accuracy is improved, but the processing time and computational load increase
Solution Approach 1:
The patent applies partial action by selectively comparing position estimates from multiple positioning models only when necessary to assess model validity. Rather than continuously processing all models at full complexity, the system performs comparisons to generate mismatch reports and assess validity, achieving improved positioning accuracy while minimizing unnecessary processing time and computational load.

AI summary
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain a first set of position estimates of the UE based on applying a first positioning model to one or more radio frequency fingerprint positioning (RFFP) measurements. The UE may obtain a second set of position estimates of the UE using a positioning technique that does not use the first positioning model. The UE may transmit a mismatch report, wherein the mismatch report is based on comparing the first set of position estimates with the second set of position estimates.
