• 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. OTDOA(p) = ri rj, (i;j) 2K, be the OTDOA measurement model. Further, y(i;j) contains the RSTD reports in (4), translated to relative distances, of the Kmost powerful eNBs, y(i;j) = h OTDOA(p) + e(i;j); (6) where the additive error term e(i;j) represents TOA mea-surement errors times the speed of light as well as NLOS propagation effects. Observed Time Difference Of Arrival (OTDOA) is also a Release 9 positioning method, in which the UE measures the downlink Positioning Reference Signal (PRS) time difference of arrivals of several neighbor cells in comparison to a reference cell. ference of arrival (OTDOA) will provide even more accurate results.
