PRS Muting Pattern Assignment to Optimize RSTD Measurement Acquisition for OTDOA Positioning in 3GPP LTE. Ramya Srinivasan, Grant A. Marshall, Guttorm R. Opshaug, Borislav Ristic, Kirk A. Burroughs, Sven Fischer, Shuping Zhang, Daniel Henriksson A, François Cardinal The OTDOA-IPDL mechanism is detailed, and implemented in a typical simulation scenario. The performance of the system is evaluated in different environments, showing the severe effects of multipath over the radio link.

Positioning reference signals are transmitted on antenna port 6. OTDOA | Downlink Observed Time Difference of Arrival. • It is defined in 3GPP Rel-9. • It is known as downlink Observed Time Difference Of Arrival. • It is assisted by UE. It means downlink signals from serving cell and multiple neighbours are received by UE.
Observed Time Difference Of Arrival (OTDOA) is also a Release 9 positioning method, in which the UE measures the downlink Positioning Reference Signal (PRS) time difference of arrivals of several neighbor cells in comparison to a reference cell. ference of arrival (OTDOA) will provide even more accurate results.
