## DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Agenda Item 1.10**: to review the regulatory procedures and associated
technical criteria of Appendix 30B without any action on the allotments,
the existing systems or the assignments in the List of Appendix **30B**;

**Background Information**: The VIII Meeting of CITEL PCC.II adopted
preliminary proposals regarding the review of Appendix **30B** under
WRC-07 Agenda Item 1.10 in CCP.II-RADIO/doc.1212/06. That document
provided a number of proposals to modify Appendix **30B**, including
proposals for no change to the current provisions of Nos. **8.18** and
**8.19** of Article **8** of Appendix **30B**. These two provisions
address the coordination of Fixed Satellite Service (FSS) earth stations
and terrestrial stations in Appendix 30B frequency bands, and the
notification of FSS earth stations respectively. Specifically, Appendix
**30B** No. **8.18** states that "No provision of this Appendix shall be
considered as modifying the requirements of Article **9** relating to
coordination between earth stations in the fixed-satellite service and
stations of terrestrial services sharing the planned bands on an equal
primary basis," and No. **8.19** stipulates that "Notification of
assignments to a specific earth station using assignments included in
the List shall be effected applying the provisions of Article **11**."

During the deliberations of Agenda Item 1.10 at the Special Committee
and the Conference Preparatory Meeting, the issue of coordination
between FSS earth stations and terrestrial stations, especially aircraft
stations, in Appendix 30B frequency bands was raised. Section
6/1.10/3.1.2.7 of the the CPM report to WRC-07, entitled *Coordination
between FSS earth stations (receiving and transmitting) on the one hand,
and terrestrial stations, on the other hand, in the Appendix 30B
frequency bands*, listed three views from administrations. While the
third view, which supported no change to the Radio Regulations, is
consistent with the current CITEL preliminary proposals, the first and
second views called for a new provision in Article **9** that would
require terrestrial stations to coordinate with typical earth stations
in Appendix **30B** bands. Additionally, according to the second view,
which addresses specifically aircraft stations sharing Appendix 30B
bands with FSS, this new Article **9** provision would also require
consequential changes to Article **8** of Appendix **30B.** These
proposed changes to Article **9** of the Radio Regulations and Article
**8** of Appendix **30B** would negate the principles laid out in Nos.
**8.18** and **8.19** of Appendix **30B**.

The FSS bands in the current Appendix **30B** were allocated at WARC-79
on a co-primary basis to space and terrestrial services. When the FSS
Plan was adopted at WARC-ORB-88, administrations knew that the spectrum
may have to be shared with terrestrial services in neighboring
countries. The FSS allocations at WARC-79 were based on the FSS earth
stations coordinating under the equivalent provisions of Nos. **9.17**
and **9.18**. Since Nos. **9.17** and **9.18** are limited to specific
earth stations, an administration can only protect Appendix 30B earth
stations at specific locations. But, if assignments to typical
Appendix 30B earth stations were allowed to be coordinated, the result
would be that the FSS would pre-empt the spectrum resource against other
co-primary services allocated in the bands. This would change the intent
of the original allocation.

The FSS Plan as provided in Appendix **30B** does not give any status to
typical earth stations that could be associated with the allotments of
the Plan. Coordination under these provisions is a bilateral process; it
can begin at anytime, and the status of the coordinated earth stations
is dependent on the results of the bilateral coordination. Therefore,
the present provisions of Article **8** of Appendix **30B** as well as
the provisions of Article **9** of the Radio Regulations provide the
appropriate and balanced procedures for the coordination of FSS earth
stations and terrestrial stations, and for the notification of Appendix
**30B** earth station assignments, and no change to the Radio
Regulations is required.

In light of the opposing views in CPM report Section 6/1.10/3.1.2.7, the
United States therefore proposes that a new proposal of no change to RR
Article **9** with respect to the coordination of FSS earth stations and
terrestrial stations in Appendix **30B** bands be added to the current
CITEL preliminary proposals. This no change proposal is needed as it is
consequential to the no change proposed for Appendix **30B** Nos.
**8.18** and **8.19** in CCP.II-RADIO/doc. 1212/06.

For the benefit of keeping the related provisions together, the existing
preliminary proposals of no change to the current provisions of Appendix
30B Nos. **8.18** and **8.19** are reproduced below**.**

APPENDIX **30B** (Rev. WRC-2000)

Provisions and associated Plan for the fixed-satellite service\
in the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz,\
10.70-10.95 GHz, 11.20-11.45 GHz and 12.75-13.25 GHz

ARTICLE 8     (WRC-03)

Procedure for notification and recording in the Master Register of
assignments in the planned bands for the fixed-satellite service

CAN/USA/1.10/73 **[NOC]{.underline}**

~~8.18~~8.17 No provision of this Appendix shall be considered as
modifying the requirements of Article 9 relating to coordination between
earth stations in the fixed-satellite service and stations of
terrestrial services sharing the planned bands on an equal primary
basis. (WRC-03)

Reasons: The coordination of FSS earth stations and stations of
terrestrial services in the Appendix 30B bands should follow the
provisions of Article 9 and therefore §8.17 should be retained without
any change.

CAN/USA/1.10/74 **[NOC]{.underline}**

~~8.19~~8.18 Notification of assignments to a specific earth station
using assignments included in the List shall be effected applying the
provisions of Article 11. (WRC-03)

Reasons: The notification of a specific earth station using a frequency
assignment included in the Appendix 30B List should be conducted in
accordance with the provisions of Article 11. Therefore, § 8.18 should
be retained without any changes.

Article **9** (only with respect to coordination of FSS earth stations
and terrestrial stations in Appendix 30B bands)

**Reasons:** The current coordination provisions of Article 9,
particularly Nos. **9.17**, **9.18,** and **9.19,** apply in the sharing
of FSS earth stations using Appendix **30B** bands and terrestrial
stations. These provisions provide a balanced coordination process that
needs to be maintained.
