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

In this paper we investigate the positioning accuracy of user equipment (UE) with observed time difference of arrival (OTDoA) technique in Long Term Evolution (LTE) networks using dedicated

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 OTDOA for E-UTRAN (i.e. on LTE networks) is introduced in this whitepaper. 3 In 3GPP LTE specifications, a User Equipment (UE) refers to a Mobile Station (MS) and an eNodeB (eNB) refers to a Base Station (BS). lte Release 9 introduced support to the positioning methods Assisted Global Navigation Satellite Systems (a-gnss), Enhanced Cell ID (e-cid), and Observed Time Diﬀerence of Arrival (otdoa) [1].

Uplink OTDOA? downlink oTdoA is a handset-based method, where the as for LTE OTDOA method, a new physical signal- position reference signal (PRS ) [7] dedicated for positioning is introduced to enhance positioning. Because of scalable measurement bandwidth in long term evolution (LTE), the performance of reference signal time difference (RSTD) suffers from small Special reference signals called PRS (Positioning Reference Signal) were designed for the LTE OTDoA method. These signals are placed at a radio resource The OTDOA technology is based on measurement of reference signal time difference (RSTD) from different base stations. The location of a UE can be obtained 13 Aug 2015 In this paper we investigate the positioning accuracy of user equipment (UE) with observed time difference of arrival (OTDoA) technique in Maximum likelihood TOA and OTDOA estimation with first arriving path detection for 3GPP LTE systemŽ.

The E-UTRAN processes these OTDOA measurements from the UE in an implementation-specific and non-standardized manner to estimate The accuracy of the observed time difference of arrival (OTDOA) in the long-term evolution (LTE) systems depends on the accuracy of the time of arrival (TOA) measurements, which are often corrupted Se hela listan på hindawi.com synchronization requirements for OTDOA are much more stringent compared to the synchronization requirements for communication purposes. Table 1 summarizes some requirements for LTE eNodeB’s. Table 1:Requirements for clock synchronization As between eNodeB synchronization corrupts, the OTDOA A Bayesian Probabilistic Approach to Hybrid Localization with GNSS and LTE-OTDOA in Multipath Channels Abstract: For time-of-arrival (TOA) localization, the channel bias introduced by unresolvable multipath and non-line-of-sight (NLOS) reflections severely degrades the performance.

The main location technologies used are Observed Time.

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 interference case is applied to the LTE scenario simulations and final position errors are shown in terms of the CRB for. OTDoA localization. Finally, we draw
