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]

This paper analyzes the Article Abstract. Toggle navigation. Home About ION The LTE Positioning Protocol (LPP) supports user Reference Signal Time Difference (RSTD) reports based on the Time of Arrival (TOA) for a Positioning Reference Signal (PRS). In the current reporting format, only one RSTD for each base station is considered, but for indoor environments this is easily biased due to fading and multipath issues, resulting in a Non-Line of Sight (NLOS) bias.

We provide an overview of the OTDOA architecture and protocols, OTDOA (Observed Time Difference Of Arrival) är en positioneringsfunktion introducerad i rel9 E-UTRA ( LTE- radio). Det är en multilaterationsmetod där User 30000 uppsatser från svenska högskolor och universitet.

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.

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

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].
