Following are the applications of OTDOA: • It is used as positioning method in all the LTE enabled mobile phones. • It is used for E911 emergency services in the USA. • It is used for various commercial applications which include maps, location based advertising on the mobile as per interest of the users and search history. 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.

Because of scalable measurement bandwidth in long term evolution (LTE), the performance of reference signal time difference (RSTD) suffers from small Special reference signals called PRS (Positioning Reference Signal) were designed for the LTE OTDoA method. These signals are placed at a radio resource The OTDOA technology is based on measurement of reference signal time difference (RSTD) from different base stations. The location of a UE can be obtained 13 Aug 2015 In this paper we investigate the positioning accuracy of user equipment (UE) with observed time difference of arrival (OTDoA) technique in Maximum likelihood TOA and OTDOA estimation with first arriving path detection for 3GPP LTE systemŽ.

One of the most promising radio-localization methods in the LTE system is OTDoA (Observed Time Difference of Arrival), in which the position is estimated on the basis of the measurement results of time difference of the arrival of the signals to the UE (User Equipment) antenna from a set of at least three base stations, as well as on the information about both the coordinates of the base stations and about transmission timing at those base stations.

30 Jan 2019 In OTDOA, an IoT device measures the time difference between specific signals from several the LTE base stations (eNodeB) and reports these

In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS). 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. Furthermore, signal bandwidth, channel condition, distance from the evolved node-B, and scatterer distribution are the affecting parameters on the OTDOA accuracy.

Baseline performance based on 3GPP 3D MIMO deployment and propagation model is investigated in [8]. The work in [9] 2016-06-29 · In addition, we propose an LTE OTDOA positioning technique that compensates the mean TOA offset in the TDOA measurements before applying a positioning algorithm, and we demonstrate the performance improvement using Monte Carlo simulations. In this paper, we do not include OTDOA errors due to the network synchronization and intercell interference. Detection of the First Component of the Received LTE Signal in the OTDoA Method 1.
