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

network user equipment positioning with the use of timing advance.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.
