The OTDOA positioning method is illustrated in Figure 1-1, where the UE measures three TOA’s relative to the UE internal time base, τ 1, τ 2, and τ 3. The measurement from eNodeB 1 is selected as reference, and two OTDOA’s are formed: t 2,1 = τ 2 – τ 1 and t 3,1 = τ 3 – τ 1. eNB 1 eNB 2 eNB 3 t 3(t 1 t 2(t 1 Measurement0 u ncer tai y t 2 t 1 t 3

Control Plane Positioning. User Plane In parallel with the 3GPP Study Item on Indoor Positioning which mainly was based on downlink OTDoA, this thesis studies on the potential use of UTDoA in LTE The downlink (OTDOA) positioning method makes use of the measured timing of downlink signals received from multiple eNode Bs at the UE. The UE measures LTE Positioning Methods- overview. 3GPP Release 9. OTDOA (Observed Time Difference of Arrival). • UE location can be tri-laterated with the knowledge of Several positioning techniques are based on time-difference-of-arrival (TDOA) or time-of arrival (TOA) measurements. Examples include OTDOA, UTDOA, GNSS, 31 May 2020 Figure 24 shows a illustration of positioning illustration by the OTDOA method using the Position. Reference Signal (PRS) (the times τxy to be It is used as positioning method in all the LTE enabled mobile phones.

38. 6.5.1.2. OTDOA Assistance Data Elements . The present document contains the definition of the LTE Positioning Protocol (LPP). 2. Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed.

Let the unknown UE’s position in two-dimensional (2D) coordinates be denoted by p = (p x;p y)T. Further, let N be the set of eNBs in the cellular network; N= f1;:::;Ng. Then, for each i2N, the known location of the eNB is given by ‘i=(‘i x;‘ i y) T. in its most basic form returns the position of the serving cell in the network. The e-cid technique improves this estimate by using measurements such as Round Trip Time (rtt) and Angle of Arrival (aoa).
