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 LTE OTDOA Positioning Reference Signals 36.211 §6.10.4 Downlink PRS OTDOA is a feature to determine the location of a User Equipment based on radio access network information Downlink OTDOA assistance provides the UE the cell PRS position for intra or inter-frequency RSTD measurements Observed Time Difference Of Arrival (OTDOA) is also a Release 9 positioning method, in which the UE measures the downlink Positioning Reference Signal (PRS) time difference of arrivals of several neighbor cells in comparison to a reference cell. OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs. In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs. actually located.

7 Dec 2018 Reference [3] provides details of OTDOA in LTE. Enhance Cell Id (E-CID) is a feature introduced in. 3GPP Rel-9[4], in which Reference Signal

• 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 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.

LTE Release 9 provides support for the following location technologies: Satellite Based Positioning: Autonomous and Assisted Global Navigation Satellite Systems (A-GNSS) such as GPS and GLONASS Mobile Radio Cellular Positioning: Observed Time Difference of Arrival (OTDOA) and enhanced Cell ID (eCID) Hybrid Methods: View Academics in OTDOA in LTE on Academia.edu. Enter the email address you signed up with and we'll email you a reset link. Enhanced Cell ID, E-CellID, or E-CID is a positioning feature introduced in rel9 E-UTRA (LTE radio). The UE reports to the network the serving cell ID, the timing advance (difference between its transmit and receive time) and the IDs, estimated timing and power of the detected neighbor cells.
