GSA POSITION ON AI 1.13 OF WRC-19 IN EUROPE (CEPT BRIEF ON AI 1.13)
Some of the 5G/IMT-2020 requirements will be met by frequency bands below 6 GHz, whereas frequency bands considered
under AI 1.13 would allow to meet some specific 5G requirements, such as provision of very high data rates in hot spot areas.
For AI 1.13, GSA supports the initial focus of the CEPT studies on the 24.25-27.5 GHz “pioneer band”. Identification of this band
for IMT would give a significant amount of spectrum for meeting specific 5G requirements. This would also allow Europe to
benefit from economies of scale due to the possibility for equipment to support a continuous “tuning range” covering the
spectrum above 27.5 GHz that will be used for early 5G deployments including in the US, Korea and Japan.
In addition to the European pioneer band 24.25-27.5 GHz, GSA is of the view that the 40.5-43.5 GHz band is also an important
band for CEPT studies under AI 1.13. GSA supports the position of RSPG that ”shift of use from other bands to this 40.5-43.5GHz
band should be avoided as far as possible in order to keep the option open to make it available for 5G in the future”.
GSA further supports studies of the all other frequency bands listed under Agenda Item 1.13. Prioritization of those bands is for
further discussion.
Finally, GSA emphasizes that spectrum harmonization remains important for the success of 5G, and even more important for
higher frequencies in order to support the development of a new 5G ecosystem. It is also of paramount importance that in order
to avoid undue limitations on the IMT usage, the sharing and compatibility studies should be based on realistic parameters,
deployment scenarios and assumptions.

•
The band is currently used in several countries of the APT region for LTE and will be available in most
European countries around the year 2020, by the start of 5G mass-scale deployments worldwide
An early availability of the band in RCC countries would enable MNOs to provide wide area 5G user
experience, including but not limited to IoT services, and support its commercial success

SPECTRUM HARMONIZATION AT HIGH FREQUENCIES
Spectrum harmonization remains important for the development of IMT as it allows for:
•
•
•
•
•
Adequate economies of scale for cost effective solutions for end users
Global roaming for end user devices
Reduced efforts in cross border coordination
Reduced equipment design complexity, preserving battery life, and improving efficiency
in spectrum use
There may be new challenges in the terminal implementation to support multiple
non-contiguous bands (above 6GHz) in the same device – especially in the initial stage
Spectrum harmonization is even more important for higher frequencies
in order to support the development of the new 5G ecosystem.

24.25-29.5 tuning range allows RCC to benefit from early
developments in 28 GHz band in US, Korea and Japan and,
in line with Europe, to consider the 24.25-27.5 GHz band
under AI 1.13 as suitable for initial deployments of 5G at
high frequencies
•
In line with the wide support during WRC-15, different
portions of spectrum within the 37.0 – 43.5 GHz range are
now being considered for 5G in various regions, e.g.:
• 37 – 40 GHz already decided in the USA
• 40.5 – 43.5 GHz in Europe
•
31.8 – 33.4 GHz supported for studies towards WRC-19 by
all Regions at WRC-15
The size of the potentially available bandwidth (1.6 GHz)
could be limited by the fact that “all emissions are
prohibited” in adjacent passive band 31.5-31.8 GHz

NEW SHARING OPPORTUNITIES
Sharing with IMT-2020 at higher frequencies:
•
•
Higher signal propagation fading
Typical deployments will address capacity enhancements in hotspot and indoor scenarios
•
•
Urban and suburban outdoor small cell deployment
•
•
•
Below rooftop antenna in urban areas has large clutter loss
Lower transmitter power than in Macro cells

h = 30 m

It is important to establish adequate protection (not over-protection) for satellite systems:

GSA VIEWS ON THE RCC SPECTRUM ROADMAP FOR 5G
(1/2)
Frequencies below 6 GHz are essential for 5G commercial success
•
700 MHz
GSA recommends to consider making the 700 MHz band available for 5G by year 2020 at the latest,
synchronised with Europe – it is essential for providing wide area 5G user experience, including but not
limited to the IoT use case.
Authorisations issued for 700 MHz should be technology neutral and allow either the deployment of 5G
from start or a technology evolution from LTE towards 5G without regulatory barriers.
•
3400-3800 MHz
GSA recommends to continue working on making the 3400-3800 MHz band gradually available for 5G,
also on a technology neutral basis – C-band is the ideal band for urban and suburban 5G coverage.
Adequate protection of incumbent services is important – the newly approved ECC Report 254
provides a full set of tools for ensuring co-existence!

GSA VIEWS ON THE RCC SPECTRUM ROADMAP FOR 5G
(2/2)
High frequencies with very wide bandwidth are needed to enable very high user peak
data rates: ~20 Gbps
•
•
26 GHz
• GSA recommends RCC to work out the conditions for the introduction of 5G in 26 GHz before WRC-19, to
enable smooth deployments of 5G services around the year 2020, aligned with the European timelines
• Conditions should take into account protection (not over-protection) of existing services in the same and
adjacent frequency bands (e.g. EESS / SRS)
42 GHz
• GSA also recommends RCC to work on the harmonisation of 40.5-42.5 GHz for 5G to enable the availability
of sufficiently large contiguous blocks of spectrum for all operators for the provision of very high data rate
