Arrival (OTDoA), detta examensarbete undersöker ytterligare prestandaegenskaper hos UTDoA i LTE. Parallellt med 3GPP:s studie för inomhuspositionering, som huvudsakligen baseras på ner-länk OTDoA, studerar denna avhandling den potentiella användningen av UTDoA i LTE med samma typ av överenskomna scenarier och simuleringsparametrar.

actually located. 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: 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. 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. It means downlink signals from serving cell and multiple neighbours are received by UE. 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 Positioning reference signals are transmitted on antenna port 6 The 3GPP consortium responded to this need by enhancing its 4G communication standard (LTE) with positioning capabilities.

for LTE-M and NB-IoT. We focus on OTDOA, which is a downlink based positioning method. We provide an overview of the OTDOA architecture and protocols,

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.

It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC). 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].
