LTE OTDOA Reference Guide With the rollout of LTE comes a new focus on enabling E911 and LBS. Current LTE standards support three independent handset based positioning techniques: Assisted Global Navigation Satellite Systems (A-GNSS), Observed Time Difference of Arrival (OTDO A), and Enhanced Cell ID (ECID).

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).

We investigate the possibility of optimizing the number of reports per minute budget on horizontal positioning accuracy using an on-demand reporting method OTDOA is a UE-assisted method, in which the UE measures the time of arrival (TOA) of specific Positioning Reference Signals (PRS) transmitted by cellular base stations and reports the measured TOA estimates to the location server.
