The GSMA’s key positions on AI 1.13

1. A successful identification of spectrum for IMT under Agenda

Item 1.13 with optimal conditions is vital to realise the full

potential of 5G networks

2. The GSMA supports the 26 GHz and 40 GHz bands

3. The GSMA also supports 66-71 GHz

4. Due to the large amount of spectrum needed for 5G services, the

range 45.5-52.6 GHz also needs to be considered

5. Technical studies show that coexistence between IMT and other

services is possible

• Most important band in all regions, supported by Europe (Recent EC

decision) Asia and the Middle East , Americas, global harmonization

potential

• The 26 GHz band is adjacent to the 28 GHz band being made

available deployed in many countries allowing wide harmonisation

• 3GPP ‘s three band classes overlap in the 26 GHz and 28 GHz bands:

n257: 26.5-29.5 GHz band; n258 : 24.25-27.5 GHz band: and n261: 27.5-

28.35 GHz band. All three band classes support channel bandwidths of

50, 100, 200 and 400 MHz and operate in the TDD duplex mode.

• Parts of the this range shared with FSS ( e-S); ISS, EESS and SRS

(S-e)

12

Deep dive – 26 GHz (24.25 to 27.5 GHz )

13

26 GHz band (24.25-27.5 GHz)

• ITU-R studies concluded sharing feasible with these

services and sufficient margins for the protection of FSS

and ISS services.

• Key pending issues:

• - OOBE limits required for protection to EESS and SRS

passive services in the adjacent band 23.6-24.0 GHz in

Resolution 750.

• - BW for the application of OOBE values 24.25-

24.25GHz/24.25-25.25 GHz/24.25-27.5GHz

• Three sub-segments of the 40 GHz range (Bands C,D and E in the

CPM report) should be treated in its entirety as a wider tuning range

in order to support the potential for global harmonisation.

• Identification of the whole band 37-43.5 GHz will allow

administrations to pick and choose parts of the band according to

national situations not only for IMT, but for FS and FSS also.

• Studies show sharing with existing services to be feasible and

separation distances to be small. In-band sharing with existing

services should be considered on a national basis.

14

Deep dive – 40 GHz (37 to 43.5 GHz)

• Time Division Duplexing (TDD) with No defined duplex gap / fixed band

arrangement.

• Radios to be designed for the entire band to provide flexibility to regulators in

dealing with incumbents/transition and national priorities.

• Radio tuning range + unpaired band plan = Flexibility for regulators, economies

of scale for affordable devices (single radio), global roaming.

• User devices operate only in the parts of the tuning range authorized in each

respective country.

• Globally harmonized spectrum are key to success in 5G

15

Flexibility to regulators and global harmonization

• MS and FS primary allocation in most of the band , secondary MS allocation in

40.5-42 GHz

• FN5.516 B identifies 40-42 GHz for HDFSS; FN 5.547 identifies. 37-40 GHz and

40.5-43.5 for HDFS (High Density Fixed Service) GHz

• Countries, within same region use different parts of this range for FS

• Harmonization possible by identifying the entire range and providing flexibility to

the Administrations to address their IMT needs and incumbents considerations

• Europe, ASMG: priority band for IMT 40.5-43.5GHz however they do not oppose

IMT identification in the band 37-40 GHz

16

Current situation in 40 GHz band

17

Deep dive – 66 GHz (66 to 71 GHz)

• In 66-71 GHz band, developments for both licensed and unlicensed

technologies for 5G use including possibly for backhaul.

• Licensing mechanisms are subject of national decisions and should

not be part of international regulations.

• The GSMA supports the identification of the band 66-71 GHz for IMT

and that it should be available for use by 5G systems with flexibility

to allow different licensing regimes, enabling both IMT and non-IMT

technologies.

66 GHz66-71 GHz

26 GHz24.25-27.5 GHz

40 GHz37-43.5 GHz

• Support IAP for

identification of 26 GHz

to IMT

• OOBE should not be

more restrictive than

-32 dBW/200MHz limit

to protect EESS

(passive)

• Support DIAP for IMT

identification for the

entire band at 37-43.5

GHz to ensure global

harmonization,

economies of scale and

roaming

• Support PP by Brazil for

IMT identification for

66-71 GHz

• Enable use by both IMT

and non-IMT

technologies

19

What about 28 GHz?

• Discussions on the band for is taking

place outside WRC-19

• This band is already allocated to fixed

and mobile services in all three Regions

• Chosen for IMT use in US, Canada,

Korea and Japan – consultations in

Australia, NZ, Chile, and others

• The ecosystem will have scale; there is

already equipment and devices

Agenda item 1.5 for ESIMs (Earth Stations In Motion) in

18/28 GHz

• This item considers the use of the frequency bands 17.7-19.7 GHz (space-to-

Earth) and 27.5-29.5 GHz (Earth-to-space) under the FSS allocations by ESIM

communicating with GSO satellites.

• ESIMs can be land, maritime or aeronautical and have significant regulatory and

interference implications for Fixed and mobile services deployed in the 28 GHz

band under coprimary MS and FS allocations

• Regulatory perspective, ESIMs on mobile platforms under FSS allocation should

operate on no interference and no protection basis (NINP).

AI 1.5 Cont’d

• ITU-R concluded there would be potential of interference to terrestrial services

from all types of ESIM transmitters in the band 27.5-29.5 GHz, while in the band

17.7-19.7 GHz ESIMs receivers would receive interference from terrestrial

networks.

• Regulatory provisions should clearly indicate responsibilities and obligations of

the entities involved in the operations of ESIMs. Key entities are: ITU notifying

Administration; ESIM authorizing Administration in a given country and ESIM

operators.

GSMA position

• CPM Report , Method B, Option 2 ( includes possibility of using parts of the band or full band

for ESIMs).

• Specifically:

• in 18 GHz, ESIMs shall operate on no protection basis;

• in 28 GHz; compliance with pfd limits on earth’s surface for A-ESIMs as per Annex 2 to

the Resolution. [Combined Option 1 and Option 2 for Pfd values to protect MS]

• M-ESIM within the minimum distance from the coastal state border 70 Km shall be subject

to prior agreement of the concerned coastal State; the maximum maritime ESIM e.i.r.p.

spectral density towards the horizon shall be limited to 12.98 dB(W/1 MHz)

• Land ESIM need to operate under the condition of not causing unacceptable interference

to receiving stations of terrestrial services operating in accordance with RR.

• Not withstanding compliance with the limits established for A-ESIMs and M-ESIMs,

responsibility to remove any real interference rests with the ESIM authorizing

Administration

AI 1.14 High Altitude Platform Stations (HAPS)

• Bands of interest which overlap with AI 1.13 and with mobile broadband for R3

are:

• 27.9-28.2 GHz ( HAPS to Ground)- existing HAPS band for 23 countries in R1

and R3, India is one of the countries as per FN 5.337A. HAPS is on NINP basis

and cannot constrain development of other services in the band..

• Under AI 1.14, there is significant interest to make the existing and new bands

global for HAPS together with pfd limits for HAPS platforms for the protection of

MS and FS., as required by Resolution 160.

AI 1.14 continues

• 38-39.5 GHz: new Candidate band for global identification . It overlaps with 40 GHz band for IMT

identification under AI 1.13. There are Options in the CPM report to use the band for HAPS transmission

or ground transmission.

• In Citel proposal, the direction used is Ground to HAPS. In this case, protection requirements for HAPS

platform receivers should not constrain development of IMT and backhaul use of this band. This should

be reflected in a Resolution associated with the FN for HAPS identification

• 47.2-47.5 GHz and 47.9-48.2GHz: Existing global band for HAPS.

• The band overlaps with the band 47.2-48.2 GHz for IMT identification under AI 1.13

• Any revisions to the existing Resolution 122 for HAPS should indicate direction for transmission in these

bands and include protection to applications under mobile service

Agenda item 9.1(9.1.1)

• Issue 9.1.1 Resolution 212 (Rev.WRC-15)

• Implementation of International Mobile Telecommunications in the frequency bands 1 885-2 025 MHz and 2 110-

2 200 MHz

• The frequency bands 1 885-2 025 MHz and 2 110-2 200 MHz have been identified in the Radio Regulations (RR) for

use by IMT. Within these broader frequency ranges, the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz are

allocated to the FS, MS and MSS on a co-primary basis. The MSS allocation is in the Earth-to-space direction in the

1 980-2 010 MHz frequency band, and in the space-to-Earth direction in the 2 170-2 200 MHz frequency band.

Resolution 212 (Rev.WRC-15) invites ITU-R to study possible technical and operational measures to ensure

coexistence and compatibility between the terrestrial component of IMT (in the mobile service) and the satellite

component of IMT (in the mobile service and the mobile-satellite service) in the frequency bands 1 980-2 010 MHz and

2 170-2 200 MHz

Studies were carried out by the ITU-R and coordination is required between the neighbor countries to achieve

compatibility

• GSMA view is that :

• NOC is required in the Radio Regulations in order to allow flexibility for deployments of terrestrial and/or satellite

component of IMT by individual countries.

• Some updates to Resolution 212 may be required

Summary

• - Identification of the bands 24.25-27.5 GHz, 37-43.5 GHz and 66-71 GHz for IMT on global

basis

• - OOBE limits should be realistic and those required to protect passive services while not

compromising use of the 26 GHz band for IMT.

• For AI 1.5, ESIMs should operate on no protection basis. Clear technical and regulatory

provisions to ensure that unacceptable interference is not caused to the use of 28 GHz for

FS and mobile broadband.

• For HAPS (AI 1.14), in bands overlapping with AI 1.13 for IMT identification and for mobile

broadband use (28 GHz; 38 GHz and 48 GHz), clear regulatory provisions for HAPS

deployment as to not impact IMT use of these bands.

• AI10 should include items for conduct of ITU-R studies for sharing and compatibility of IMT

in specific bands in the range 6-24 GHz and also rationalization of C band .

• Consider improvement in harmonization of the 600 MHz and 3.3-3.4 GHz and 3.6-3.7 GHz

and 4800-4990 MHz for IMT

28

Improve harmonization of some bands from WRC-15

for IMT

• Review FN’s for the band 470 (614)- 698 MHz (FN 5.296A);

3300-3400 MHz; 3600-3700 ( FN 5.434) MHz and 4800-

4900 MHz ( 5.441B) with the view to improve harmonization

• Process: Interested Administrations submit requests to

WRC-19 subject to no objection from affected neighbour

countries
