• 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. In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS). 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) Abstract: 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 by various errors caused by non-light-of-sight propagation, multipath interference, noise, and path detection techniques.
