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.

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
