## DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE[^1]

**Agenda Item 1.22**: to consider progress of ITU-R studies concerning
future development of IMT-2000 and systems beyond IMT-2000, in
accordance with Resolution **228 (WRC-2000)**;

**Background Information**: WRC-2000 considered issues related to
IMT-2000, resulting in the identification of additional spectrum for the
terrestrial component of IMT-2000 in the Radio Regulations **5.317A**
and **5.384A**. This spectrum was identified in addition to that
initially identified for IMT-2000 at WARC-92 in footnote **5.388**.
WRC-2000 also identified existing global MSS allocations as being
available for use by the satellite component of IMT-2000, in accordance
with Resolution **225**.

Resolution **228** **(WRC-2000),** which is related to agenda item 1.22,
invites ITU-R to continue studies on overall objectives, applications
and technical and operational implementation for the future development
of IMT-2000 and systems beyond. ITU-R Working Party 8F has developed a
Draft New Recommendation on the vision, framework and overall objectives
of the future development of IMT-2000 and systems beyond IMT-2000
\[DNR-VIS\], which is expected to be approved at the ITU-R Study Group 8
meeting in February 2003. Studies will continue to be carried out in WP
8F, and are scheduled to be completed before WRC-07. The results of
these studies will indicate which requirements should be reviewed by
WRC-07.

**Proposal**:

**USA/ /1 [NOC]{.underline}**

Article 5

Frequency Allocations

**Reason:** ITU-R has not completed the studies on spectrum requirements
and potential frequency ranges suitable for the future development of
IMT-2000 and systems beyond IMT-2000.

RESOLUTION 228 ([rEV.]{.underline} WRC-~~200~~0[3]{.underline})

Studies to consider requirements [and frequency matters related
to]{.underline} ~~for~~ the future development of IMT‑2000 and systems
beyond IMT‑2000 as defined by ITU-R

The World Radiocommunication Conference ~~(Istanbul, 2000)~~[(Geneva,
2003)]{.underline},

considering

*a)* that International Mobile Telecommunications-2000 (IMT-2000[)
systems have started operation in some countries in]{.underline} ~~is
scheduled to start service around~~ the year 2000~~, subject to market
and other considerations~~;

~~*b)* that Question ITU-R 229/8 addresses the future development of
IMT-2000 and systems beyond IMT‑2000;~~

*~~c)~~[b)]{.underline}* that the technical characteristics of IMT-2000
are specified in ITU-R and ITU-T Recommendations, including
Recommendation ITU-R M.1457 which contains the detailed specifications
of the radio interfaces of IMT-2000;

[*c)* that Question ITU-R 229/8 addresses the future development of
IMT-2000 and systems beyond IMT‑2000;]{.underline}

[*d)* that the ITU-R has adopted \[Draft New\] Recommendation ITU-R
M.\[DNR-VIS\], which addresses the vision, framework, and overall
objectives of the future development of IMT-2000 and systems beyond
IMT-2000;]{.underline}

[*e)* that \[Draft New\] Recommendation ITU-R M.\[DNR-VIS\] has
identified the new elements of systems beyond IMT-2000 that are to be
developed, and has stated that such systems will closely inter-work with
the currently operating IMT-2000 and with future developments of
IMT-2000;]{.underline}

[*f)* that the technical characteristics of systems beyond IMT-2000 have
not been specified in an ITU-R Recommendation, but remain under study
within the ITU-R;]{.underline}

[*g)* that it was eight years ahead of the IMT-2000 initial deployment
that **WARC-92** identified the spectrum for IMT-2000 in No. **5.388**
and under the provisions of Resolution **212 (WARC‑92)**]{.underline};

*~~d)~~[h)]{.underline}* that telecommunication [and
information]{.underline} technologies evolve rapidly;

*~~e)~~[i)]{.underline}* that, [as it is with many other service and
systems,]{.underline} adequate spectrum availability is a prerequisite
for the technological and economic success of the future development of
IMT-2000 and systems beyond IMT‑2000;

*~~f)~~[j)]{.underline}* that the demand for the provision of multimedia
applications such as high-speed data, IP‑packet and video by mobile
communication systems will continue to increase;

*~~g)~~[k)]{.underline}* that the future development of IMT-2000 and
systems beyond IMT-2000 is foreseen to address the need for higher data
rates than those [of]{.underline} currently [deployed]{.underline}
~~planned for~~ IMT‑2000 [systems]{.underline};

*~~h)~~[l)]{.underline}* that, for global operation and economy of
scale, it is desirable to agree on common technical, operational and
spectrum-related parameters of systems;

*~~i)~~[m)]{.underline}* that it is therefore timely to study technical,
spectrum and regulatory issues pertinent to the future development of
IMT-2000 and systems beyond IMT‑2000[;]{.underline}~~,~~

[*n)* that Question ITU-R 77-4/8 addresses adaptation of mobile
radiocommunications technology to the needs of developing countries,
including the optimum arrangements and technical characteristics needed
to use mobile technology/equipment in urban, rural or remote
areas;]{.underline}

[*o)* that all existing services, some of which are also evolving to
permit the use of higher data rates and throughput within their
allocations in order to meet increasing user demands and requirements,
should be taken into account in any studies evaluating potential
spectrum for systems beyond IMT-2000,]{.underline}

*[noting]{.underline}*

[*a)* that the IMT-2000 radio interfaces as defined in Recommendation
ITU-R M.1457 are expected to evolve within the framework of the ITU-R
beyond those initially specified, to provide enhanced services and
services beyond those envisaged in the initial
implementation;]{.underline}

[*b)* that the use of the spectrum identified for IMT-2000 does not
preclude the use of these bands by any station in the services to which
they are allocated and does not establish priority in the Radio
Regulations,]{.underline}

recognizing

*a)* the time necessary to develop and agree on the technical,
operational, spectrum and regulatory issues associated with the
continuing enhancement of mobile services;

*b)* that service functionalities in fixed and mobile networks are
increasingly converging;

*c)* that future mobile systems will ~~require the adoption of~~
[employ]{.underline} more spectrum-efficient techniques [than those used
by current mobile systems]{.underline};

*d)* the needs of developing countries for the
[cost-effective]{.underline} implementation of advanced mobile
communication technologies [and the propagation characteristics of lower
frequency bands that result in larger cell sizes;]{.underline}~~,~~

[*e)* that the review of IMT-2000 spectrum requirements at WRC-2000
concentrated on the bands below 3 GHz and that these bands remain
technically desirable for both IMT-2000 and systems beyond
IMT-2000;]{.underline}

[*f)* that, to the extent that they may not be the same, it would be
preferable for the location in the radiofrequency spectrum of bands that
support systems beyond IMT-2000 to be reasonably close to the location
of bands already identified for IMT-2000 and predecessor
services;]{.underline}

[*g)* that many countries have not yet made available spectrum already
identified for IMT-2000, due to various reasons, including the use of
these bands by existing services;]{.underline}

[*h)* that studies may show that the identification of certain bands for
use by the future development of IMT-2000 and systems beyond IMT-2000
may be precluded by the use of these bands by existing
services,]{.underline}

resolves

1 to invite ITU-R to [further study, and develop Recommendations
on,]{.underline} ~~continue studies on overall objectives, applications
and~~ technical and operational [issues relating
to]{.underline}~~implementation, as necessary, for~~ the future
development of IMT-2000 and systems beyond IMT-2000;

2 to invite ITU-R to [complete studies, in time for WRC-\[07\],
on]{.underline} ~~study~~ the spectrum requirements and potential
frequency ranges suitable for the future development of IMT-2000 and
systems beyond IMT-2000, [taking into consideration the bands currently
identified for IMT-2000 and the evolution of IMT-2000 and pre-IMT-2000
systems therein through advances in technology]{.underline}~~and in what
time‑frame such spectrum would be needed~~;

[3 that, taking into account the *recognizing* above, the studies in
*resolves* *1* and *2*:]{.underline}

~~3~~[4]{.underline} that [WRC-\[07\] consider, as a matter of
urgency,]{.underline} the [results of ITU-R studies and review
the]{.underline} requirements [and frequency related matters related
to]{.underline}~~for~~ the future development of IMT‑2000 and systems
beyond IMT‑2000[,]{.underline} ~~be reviewed by WRC‑05/06, taking into
consideration the results of ITU‑R studies presented to WRC‑03~~[in
accordance with this Resolution]{.underline}~~,~~[;]{.underline}

[5. that the studies contemplated in *resolves 1-3* above take into
consideration the needs of developing countries,]{.underline}

urges administrations

to participate actively in the studies by submitting contributions to
ITU-R.

**Reasons:** Appropriately modify Resolution **228 (WRC-2000)** for
further studies to consider detailed requirements and ensure that the
interests of existing services are taken into consideration in these
studies, and to enable WRC-07 to review these requirements. The Unites
States is still considering what action should be taken concerning this
issue as related to agenda item 7.2.
