Improving the Performance of OTDOA based Positioning in

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. 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) The 3GPP consortium responded to this need by enhancing its 4G communication standard (LTE) with positioning capabilities.

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. 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.

types of environment, LTE uses complementary positioning methods. The main location technologies used are Observed Time. Difference of Arrival (OTDOA) LTE™ is a Trade Mark of ETSI registered for the benefit of its Members and of the The downlink (OTDOA) positioning method makes use of the measured mechanisms will not work well, requiring further enhancement on the LTE positioning solutions of Observed Time Difference Of Arrival (OTDOA) and.

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. In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS). OTDOA.
