Performance of OTDOA Positioning in Narrowband IoT - DiVA

PAPR Peak-to-av erage power ratio. PF Paging frame. PH Paging hyperframe. tutorial, we focus only on the in-band operation mode as it. OTDOA is a handset-based technology that relies on measurement of the time difference of arrival of special Positioning Reference Signals (PRS) from 2 or more neighboring LTE base stations. This technology is most useful when GNSS is not available because it can provide reasonably accurate positioning (about 25-200m) indoors or in environments with limited visibility of the sky. 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 Abstract: Abstract—This contribution describes the first implementation of an integrated modem supporting NB-IoT OTDOA positioning.

OTDOA (Observed Time Difference Of Arrival) is a positioning feature introduced in rel9 E-UTRA (LTE radio). It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC). requirements to improve the positioning accuracy capabilities. Similarly to an OTDOA procedure, a E - CID procedure is initiated through the LPP protocol by the reference signals PRS added in release 9, meant to be used by the UE for OTDOA positioning a type of multilateration In the uplink there are three physical locate the telephone. Such systems include Google Maps, as well as, LTE s OTDOA OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users. If measure-ments from three or more stations are available, a position can be estimated [1].

Simulation of Location Based Services in Mobile Networks . LoCation Services (LCS) test suite to support simulation of location based services in GSM (Lb, Lg, Lh interfaces), UMTS (IuPC, Lg, Lh), and LTE (SLs, SLg, SLh interfaces) networks. After initial delivery in late 2017 of ‘Non-Stand-Alone’ (NSA) NR new radio specifications for 5G, much effort focused in 2018 on timely completion of 3GPP Release 15 – the first full set of 5G standards – and on work to pass the first milestones for the 3GPP submission towards IMT-2020.

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 Abstract: Abstract—This contribution describes the first implementation of an integrated modem supporting NB-IoT OTDOA positioning. The integration of a dedicated hardware accelerator provides the necessary processing power for time-domain cross-correlations of OFDM signals and enables successful position fixes at highly negative SINR. As mentioned there are various ways to obtain user position. Some of them utilize trilateration, e.g., Observed Time Difference of Arrival (OTDoA) defined for cellular networks in LTE Positioning Protocol (LPP) [], 802.15.4a ultra wide band (UWB) [], or different implementations of GNSS, e.g., Global Positioning System (GPS) or Galileo [].Other ones, may use triangulation. 5G URRP-AMF. 5G UE Reachability Request Parameter for AMF. posted on 2019-04-08 07:35:04 - 5G Tutorial Tutorials These three measurements, of course, require three OTDOA-capable cells, which are measured in pairs, respectively.

The ESMLC based on these time differences and knowledge of the enodeBs locations calculates the UEs' position. 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. Like downlink OTDOA; the method used to determine position of UE using uplink transmissions is known as U-TDOA. Refer OTDOA basics and working >> . Following table mentions difference between GPS and OTDOA methods used to determine position of UE. such as OTDOA, can be a better choice for indoor locations and urban canyon environments, while Adaptive Enhanced Cell Identity (AECID) is a good fit in all environments and is especially suitable for terminals that are not equipped with GNSS receivers.

This page compares OTDOA vs U-TDOA and mentions difference between OTDOA and U-TDOA.OTDOA method measures UE position based on downlink signal measurement while U-TDOA method measures UE position based on uplink signal measurement. Like downlink OTDOA; the method used to determine position of UE using uplink transmissions is known as U-TDOA. Refer OTDOA basics and working >> . Following table mentions difference between GPS and OTDOA methods used to determine position of UE.
