5G NETWORK USER EQUIPMENT POSITIONING WITH THE USE OF TIMING ADVANCE

DOI: 10.31673/2786-8362.2025.016173

Abstract

This article is devoted to the study of positioning methods for user equipment
for navigation, industry and public safety. In scenarios where the use of GPS is complicated by different
factors, positioning can be provided using the standard functionality of the cellular network. This paper
discusses positioning methods in 5G networks, in particular, those based on E-CID, field strength,
difference in time of arrival, and LPHAP, and proposes a method based on timing advance. The proposed
method is aimed at simplifying the positioning procedure, ensuring high accuracy of determining the
location of subscriber equipment and reducing power consumption during positioning. The method of
reducing the error by averaging a number of TA values is investigated. Methods for reducing UE power
consumption in the location process for critical scenarios are investigated. Possible problems that lead to
discrepancies in the time synchronization required to achieve the highest possible positioning accuracy
when using the presented method are considered.
Keywords: 5G, positioning, timing advance, navigation
