OTDOA positioning in legacy LTE systems is widely stud-ied in the literature. For example, [6] uses real measurements and investigates channel impacts on positioning accuracy. An error analysis of OTDOA is reported in [7]. Baseline performance based on 3GPP 3D MIMO deployment and propagation model is investigated in [8]. The work in [9]

the interference case is applied to the LTE scenario simulations and final position errors are shown in terms of the CRB for. OTDoA localization. Finally, we draw

Nowadays, radio-localization technologies constitute a rapidly developing industrial branch. There is a 2. Proposed Algorithm. The literature presents several different algorithms for detecting the (OTDOA) as a major positioning method in 3rd Generation Partnership Project (3GPP) specification has been deeply researched in Long Term Evolution Advanced (LTE-A) system.

In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS). 8.2.1 General. In this version of the specification, only OTDOA based on LTE signals is supported. In the OTDOA positioning method, the UE position is estimated based on measurements taken at the UE of downlink radio signals from multiple E-UTRA TPs (possibly including PRS-only E-UTRA TPs from a PRS-based TBS), along with knowledge of the geographical coordinates of the measured TPs and their 8.2.1 General.

OTDOA In LTE Networks Abstract. A computer implemented method for providing OTDOA timing information comprising defining an FFT window pair for estimating a value of reference signal time difference "RSTD" for at least one base station and a reference cell, receiving a PRS from the at least one base station and the reference cell, executing an FFT per OFDM symbol of the PRS for each FFT window

Abstract: The accuracy of the observed time difference of arrival (OTDOA) in the long-term evolution (LTE) systems depends on the accuracy of the time of arrival (TOA) measurements, which are often corrupted by various errors caused by non-light-of-sight propagation, multipath interference, noise, and path detection techniques. Furthermore, signal bandwidth, channel condition, distance from the evolved node-B, and scatterer distribution are the affecting parameters on the OTDOA accuracy.

OTDOA. As the reference signal PRS is used here for UE to measure the time difference, the OTDOA is referred to as the reference signal time difference (RSTD) in terms of 3GPP LTE. Similarly, for E-CID, the so-called UE Rx–Tx time dif-ference is measured. The UE Rx–Tx time difference is deﬁned as the difference between the UE received (Rx) Abstract: The accuracy of the observed time difference of arrival (OTDOA) in the long-term evolution (LTE) systems depends on the accuracy of the time of arrival (TOA) measurements, which are often corrupted by various errors caused by non-light-of-sight propagation, multipath interference, noise, and path detection techniques.

This might be one advantage compared to Observed Time Difference of Arrival (OTDoA), while further performance properties of UTDoA in LTE are investigated

2014-06-06 · This document describes the functionalities for the support of OTDOA location in LTE as currently defined in 3GPP (and OMA). It is intended as a one stop guide to provide an overview of the OTDOA feature for operators and manufacturers interested in the deployment 2 OTDOA is the positioning method for UTRAN and for E-UTRAN, as specified in Reference [2]. Only OTDOA for E-UTRAN (i.e. on LTE networks) is introduced in this whitepaper.
