How does E-CID positioning works in NB-IoT? Another method for NB-IoT positioning in 3GPP R14 is Enhanced Cell ID (E-CID), based on Cell of Origin (COO). 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. 3GPP Specification Change Request records for: 24.080.

Narrowband PRS (NPRS) supporting downlink OTDOA based positioning. Speciﬁcally, for in-band deployment, PRS symbols are reused also in the NPRS, which typ-ically is extended with a large number of repetitions to allow accumulation at the device for detectability. OTDOA positioning in legacy LTE systems is widely studied in the literature.

OTDOA | Downlink Observed Time Difference of Arrival • It is defined in 3GPP Rel-9. • It is known as downlink Observed Time Difference Of Arrival.

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.
