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. Geofencing in 5G – “3GPP Release 15 will use LPP as a positioning protocol and support the associated positioning methods such as Global Navigation Satellite System (GNSS) and Observed Time Difference of Arrival (OTDOA)). As the 5G standard evolves and matures, 5G-specific positioning methods and protocols will find their way into 5G geofencing.” This page compares GPS vs U-TDOA and mentions difference between GPS and U-TDOA.GPS stands for Global Positioning System and U-TDOA stands for Unlink Time Difference of Arrival.U-TDOA is uplink method similar to downlink OTDOA. NOTE 3: 5G positioning nodes are infrastructure equipment deployed in the service area to enhance positioning capabilities (e.g.beacons deployed on the perimeter of a rendezvous area or on the side of a warehouse).

• It is assisted by eNB. The uplink transmissions from UE are received by highly sensitive receivers which will determine the time differences of arrival and hence UE position. OTDOA is a subscriber location technique which was introduced in Release 9 of the 3GPP specifications. OTDOA is based on the mobile taking TDOA measurements from the PRS (Positioning Reference Signal) associated with the neighbouring eNBs that the mobile is able to receive.
OTDOA is based on the mobile taking TDOA measurements from the PRS (Positioning Reference Signal) associated with the neighbouring eNBs that the mobile is able to receive. • In uplink OTDOA, eNBs receive the uplink transmission from UE and determines position of UE. Uplink OTDOA (U-TDOA) is specified in 3GPP Release-11. How OTDOA Works • OTDOA uses hyperbolic multilateral algorithm to determine time of arrival of downlink signals from multiple eNBs (includes 1 serving eNB and 2 or more neighbour eNBs). OTDOA or UTDOA?

Techniques for observed time difference of arrival (OTDOA) positioning in development or to be developed in the future (e.g., fifth generation (5G), 6G, etc.). Since the initial development of 5G began, we have tried to ensure that our 5G courses provide a concise yet detailed understanding of the overall 5G System.
