OTDOA (Observed Time Difference Of Arrival) is a positioning feature introduced in rel9 E-UTRA (LTE radio). It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC). 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. What is OTDOA | How OTDOA works, OTDOA applications, benefits. This page compares OTDOA vs U-TDOA and mentions difference between OTDOA and U-TDOA.OTDOA method measures UE position based on downlink signal measurement while U-TDOA method measures UE position based on uplink signal measurement.

If measure- LTE Observed Time Difference of Arrival (OTDOA) method in the other hand uses the measured timing of downlink signals received from multiple eNBs to locate the UE according to the neighboring eNBs. OTDOA can be supplement AGPS in dense urban and indoor areas where UE can detect position reference signals (PRS) from three or more eNBs. such as OTDOA, can be a better choice for indoor locations and urban canyon environments, while Adaptive Enhanced Cell Identity (AECID) is a good fit in all environments and is especially suitable for terminals that are not equipped with GNSS receivers.
