Abstract: A computer implemented method for providing OTDOA timing OTDOA | Downlink Observed Time Difference of Arrival • It is defined in 3GPP Rel-9. • It is known as downlink Observed Time Difference Of Arrival. • It is assisted by UE. 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] 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 recent 3rd generation partnership project (3GPP) long term evolution (LTE) cellular environment, multiple observed time difference of arrival (OTDOA) based 6 Jun 2014 Observed Time Difference Of Arrival (OTDOA) is a downlink positioning method in LTE. Rel-9. It is a multilateration method in which the User LTE OTDOA Positioning Reference Signals. Moved to www.sqimway.com. Back to top.
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.

Improving the Performance of OTDOA based Positioning in NB-IoT Systems deployed in long-term-evolution (LTE) based narrow-band Internet-of-things Enhancements in LTE OTDOA Positioning for Multipath Environments.
Furthermore, signal bandwidth, channel condition, distance from the evolved node-B, and scatterer distribution are the affecting parameters on the OTDOA accuracy. 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 relative downlink timing.
