to positioning via OTDOA method can be found in [1]. The positioning accuracy in OTDOA method depends on various factors e.g., network deployment, signal propagation condition, and properties of PRS. For 4G cellular (LTE) indoor users, positioning accuracy can be around 50 meters [2]. For upcoming 5G

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.

2020-10-23 · These techniques are designed to meet initial 5G requirements of 3 and 10 meters for indoor and outdoor use cases, respectively. In Release 17, precise indoor positioning functionality will bring sub-meter accuracy for industrial IoT use cases. 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. Ericsson’s Router 6000 is an ideal router solution, purpose built for 5G RAN. 5G Tutorial; OTDOA. Observed Time Difference of Arrival. 5G URSP. 5G UE Route Selection Policy.

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. • 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).

6 Jun 2014 The UE measurement for OTDOA positioning is the Reference Signal Time Difference. Measurement (RSTD), specified in 3GPP TS 36.214 [5].

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. In LTE DL-TDoA was refered to as OTDoA [13]. In 4G the downlink signal used for OTDoA was the PRS. OTDoA uses multilateration in which the UE measures the  Observed TDOA (OTDOA) estimation of the Gaussian noise is computed to detect the OTDOA.

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.
