Language. About Qualcomm Careers Offices Contact Us Downlink OTDOA is specified in 3GPP Release-9. • 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. As the reference signal PRS is used here for UE to measure the time difference, the OTDOA is referred to as the reference signal time difference (RSTD) in terms of 3GPP LTE. Similarly, for E-CID, the so-called UE Rx–Tx time dif- ference is measured.

With the above extensive OTDOA enhancements considered for feMTC and NB-IoT, based on the limited time-dispersion/ time-spread/ multipath EPA (Extended Pedestrian A model) 3GPP channel scenario with outdoor deployment of 1.732km ISD (Inter-Site Distance), the 50m positioning accuracy for 67% of the UEs is achievable for both device types. OTDOA | Downlink Observed Time Difference of Arrival • It is defined in 3GPP Rel-9.

The 3GPP Release 14 introduces OTDOA and E-CID positioning methods into NB2 for higher location accuracy. Multicast in NB2. The NB2 devices contain Multicast transmission mode, which the NB1 device does not have. Enhanced NB2 OTDOAとその利点 3GPPリリース14では、NB-IoTがさらに改善され、ユーザー体感が向上しています。OTDOA（Observed Time Difference Of Arrival）は、ダウンリンクベースの位置決定方法であり、位置決定精度を高めるためのNB-IoT位置決定方法の1つとして3GPPで記述されています。 Difference Of Arrival (OTDOA) Positioning Technique in 3GPP LTE 1Sowmya GM , Nagaraj K2, Sampath Kini3 1PG Student, Dept Of CSE,NMAM Institute Of Technology, Nitte,India 2 Manager-Embedded Product Design, Communications BU ,TATA ELXSI Bangalore, India 3Assistant Professor, Dept Of CSE,NMAM Institute Of Technology,Nitte,India This paper gives an overview of algorithms for positioning a mobile phone using 3GPP-FDD mode signals.
