In Release 14, a new reference signal was designed for positioning of NB-IoT, referred to as Narrowband Positioning Reference Signal (NPRS), which has Refer OTDOA basics and working >>. U-TDOA | Uplink Time Difference of Arrival • It is defined in 3GPP Rel-11. • It is known as uplink Time Difference Of Arrival. • 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.
UMTS, LTE and 5G network on earth, and is commercially proven to fully interwork OTDOA, WiFi and Hybrid location for GSM, UMTS, 5G and IMS networks.

Network Synchronization Products. We serve the 5G market with our leading-edge network synchronization timing IC … This page covers OTDOA (Observed Time Difference of Arrival) basics.It mentions how OTDOA works in LTE system and mentions applications of OTDOA.The advantages or benefits of OTDOA are also mentioned.The links to comparison between OTDOA with GPS and U-TDOA are also mentioned. 2020-10-23 With the right router in the access network delivering high quality, highly reliable timing and sync, the most advanced RAN features and new spectrum in both LTE Advanced and 5G networks can be realized in the most cost-effective way.

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).
