Specialist Task Force 603:
Measurement campaign to confirm simulation parameters to define Urban Rail ITS protected zones in 5915-5925 MHz

What we do

We are working in parallel on the following tasks: identification of sites in cities to perform field strength measurements, define different scenarios for measurements, specify test set-up with measurement process for each scenario.

When these three first tasks will be completed, we will perform field strength measurements with the specified scenarios and process on the selected sites and finally the measurement will be analysed.

For more details, see our Terms of Reference

Why we do it

ETSI Technical Report ETSI TR 103 580 v1.1.1 published in August 2019, proposes different methods to allow efficient sharing of the frequency band 5.9 GHz between Urban-Rail-ITS and Road-ITS and also concluded that complementary studies are required on the following tasks:
•    Identify methods to define protected zones
•    Define protected zone detection methods
•    Define mitigation techniques to apply in protected zones

To define protected zone, propagation simulation has been performed to evaluate the level received by Urban-Rail-ITS base station and also train.
The TR 103 580 v1.1.1 has concluded that a measurement campaign will be needed to validate the propagation simulation results.

These results of the measurement campaign are expected in 2021 and will establish the baseline for the complementary studies on mitigation techniques aiming to update the current ETSI TR 103 580 under ETSI TC RT JTFIR.

How we do it

The STF is composed of the six following tasks:
T1    Identification of the relevant test cases   
T2    Identification of the relevant areas to conduct the measurements
T3    Description of test procedures and test tools for each case
T4    Planning of the measurements
T5    Conduct the measurement campaign
T6    Conclusion of the measurement campaign, finalization and publication of the TR 103 704

The Task T1, T2 and T3 are the most critical ones due to tight time schedule. For efficiency, the workload will be shared among members of the STF in the most efficient way. There will be different main contributors for some tasks T1, T2 and T3 all there will be reviewer for all the tasks.

The TC RT and the TC ITS will both be involved in the consultation phase and approbation of deliverables process. This would be undertaken by the TC RT JTFIR.

The CEPT/ECC will be informed of the work progress.

The TC ERM will be informed by the TC RT JTFIR.

Deliverables

The STF 603 will provide the following deliverable:

•    TR 103 704 is the main deliverable
•    In addition, the following reports and draft will be issued:
o    Progress report#1
o    Interim Report 1 to the EC/EFTA (including the planification of the measurements) to be made available and approved by ETSI Secretariat
o    Early Draft of the TR 103 704 made available to TC RT JTFIR, RT & ITS
o    Interim Report 2 to the EC/EFTA (including a first feed-back of the different measures, the progress of each one, their success or not regarding the procedures expected) to be made available and approved by ETSI Secretariat
o    Stable Draft of TR 103 704 made available to TC RT JTFIR, RT & ITS
o    Final Draft of TR 103 704 approved by TC RT JTFIR, RT & ITS and published
o    Final report to the EC/EFTA to be made available and approved by ETSI Secretariat
