Report of the Second Conference Preparatory Meeting for WRC-19 (CPM19-2)
(Geneva, 18-28 February 2019)
The Conference Preparatory Meeting of WRC-19 (CPM19-2) chaired by Mr Khalid Al Awadi of the United Arab Emirates was held on 18-28 February 2019. The Meeting was attended by 1304 participants from 107 countries and 83 sector members, according to the ITU-R registration system. This report is published on the ECC website to provide an overview of the overall activities of the CPM19-2.
The work of CPM19-2 was organised according to structure of the CPM Report. Six Working Groups (WGs) corresponding to the Chapters of CPM19-2 Report were established by the meeting to undertake relevant responsibilities:
- WG1 (Chapter 1) on Land Mobile and Fixed Services, dealing with agenda items 1.11, 1.12, 1.14 and 1.15.
- WG2 (Chapter 2) on broadband applications in the Mobile Service, dealing with agenda items 1.13, 1.16 and 9.1 (issues 9.1.1, 9.1.5, 9.1.8).
- WG3 (Chapter 3) on Satellite Services, dealing with agenda items 1.4, 1.5, 1.6, 7 and 9.1 (issues 9.1.2, 9.1.3, 9.1.9).
- WG4 (Chapter 4) on Science Services, dealing with agenda items 1.2, 1.3 and 1.7.
- WG5 (Chapter 5) on Maritime, Aeronautical and Amateur Services, dealing with agenda items 1.1, 1.8, 1.9 (1.9.1, 1.9.2), 1.10 and 9.1 (issue 9.1.4).
- WG6 (Chapter 6) on General Issues, dealing with agenda items 2, 4, 9.1 (issues 9.1.6, 9.1.7) and 10.
Each Working Group issued an appropriate number of Sub-Working Groups to address the various agenda items.
A Drafting Group of the plenary was also set to consider an input document from the Russian Federation regarding the scope of application of footnote RR No. 5.441B. This footnote was approved at WRC-15 and states that the criterion of the power flux-density (pfd) produced by the IMT station in the mobile service in three countries of Region 3 in the frequency band 4800‑4990 MHz is subject to review at WRC-19. After discussion, CPM19-2 agreed that no additional issue should be added under agenda item 9.1.1 and included some new text in the CPM Report, also highlighting that the Director of the Bureau may wish to consider this topic for the preparation of his Report to WRC-19, as appropriate.
More details on the outcome on the various agenda item is given below.
Agenda item 1.1: to consider an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC- 15)
Eight documents were received and considered by the meeting. The final version of the CPM Report contains four Methods, including Method D which proposes “No Change” to the Radio Regulations and Method B having two Options. The major changes applied by CPM19-2 are the following:
- The Options under Method B, which proposes an allocation to the amateur service on a secondary basis, were changed to bandwidths of 200 kHz (B1) and 2 MHz (B2).
- The bandwidths in Methods A (primary allocation to the amateur) and Method C (allocation partly primary and partly secondary) will be determined at WRC-19. A new Resolution was added for these Methods, dealing with the coexistence of the amateur service and wind profiler radars.
In addition, the text covering sharing with existing services was revised and clarified. Additional text was added to the sections on background, advantages and disadvantages, and regulatory footnotes to remove ambiguities about protection of services in the border area between Region 1 and Region 3. Changes were also applied to the proposed regulatory footnotes to improve their consistency between the various Methods.
Agenda item 1.2: to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 (WRC-15)
Seven contributions were received on this agenda item. During the meeting, Methods C for the 399.9-400.05 MHz MSS band and F in the EESS/METSAT band 401-403 MHz were respectively merged with a new method proposed by the Russian Federation. This introduced a limit of e.i.r.p. within a band of 4 kHz, which avoids, to some extent, the aggregation of several emissions per carrier to artificially recreate a high power telecommand link. This is in line with the CEPT view. Further discussion on this will take place within CPG PTA.
The CPM text contains now four Methods for the 399.9-400.05 MHz MSS band as a contribution from Canada proposed a method with a segmentation of 30 kHz for high power telecommand controls. Therefore, the Methods for the MSS band are: “No Change” (Method A), Method C without segmentation, Method B segmentation at 20 kHz and Method D segmentation at 30 kHz. For the 20 kHz and 30 kHz part for high power telecommand, no power limit is specified. The draft European Common Proposal (ECP) is in line with Method C dealing with no segmentation.
For the 401-403 MHz band, a contribution from USA proposed a new method, which led to strong discussion, as it included a Resolution whose content is still undefined. The discussion suggested that a transition period without any power limit is aimed, differently from what proposed by Canada having an e.i.r.p. limitation. It was not clear if the introduction of time limits is considered. It was therefore proposed an "empty" Method without any indication of duration, possible e.i.r.p. limits or ranges of frequencies (it is not known if frequency bands within the GSO part of the band 401-403 MHz are targeted). The Methods for the 401-403 MHz band are: Method E with e.i.r.p. limits in the entire 2 MHz range (this is considered in the current draft ECP), Method F introduced based on the proposal from Canada (possibility to put telecommand links in GSO bands with e.i.r.p. limitations and time) and Method G based on the proposal from USA described above.
Agenda item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15)
Six contributions were submitted to CPM19-2 providing amendments to the draft CPM Report for this agenda item. Contributions from USA and Russia proposed to change Method B, while Germany introduced a new Method C based on the current draft European Common Proposal (ECP). In principle, those documents were all on the same line. One document from ASMG proposed the inclusion of one disadvantage for Method B. The documents from APT and Iran introduced text for the protection of the broadcasting service in the 470-694 MHz adjacent band.
The meeting tried to merge the contributions into one combined Method B, but no compromise was reached, due to the diverging views. Therefore, a new Method C based on the German input was included in the CPM Report, also reflecting all the contributions submitted to the meeting. Method B remained almost unchanged and includes several options. Method A proposes “No Change” to the Radio Regulations.
Agenda item 1.4: to consider the results of studies in accordance with Resolution 557 (WRC 19), and review, and revise if necessary, the limitations mentioned in Annex 7 to Appendix 30 (Rev.WRC-11), while ensuring the protection of, and without imposing additional constraints on, assignments in the Plan and the List and the future development of the broadcasting-satellite service within the Plan, and existing and planned fixed-satellite service networks
In total five contribution were received by the meeting, including the input from CEPT. Before CPM19-2, CEPT had consolidated its preliminary position for all the limitations except for limitations A1a and A2a. For these limitations CEPT was still discussing between Methods B and C. Considering the contributions to this CPM meeting and thanks to the compromise reached by the administrations, CEPT agreed on a combined solution between Methods B and C for these two limitations. The solution consists in applying Method C (test points) for orbital separations between 0º to 4.2º and Method B (service area) above 4.2º. CEPT proposed to the CPM19-2 to merge Methods B and C according to this position. The proposal was discussed and accepted, so the CPM Report eventually contains only two Methods: Method A, which proposes “No Change” to the Radio Regulation, and Method B, which CEPT supports.
Agenda item 1.5: to consider the use of the frequency bands 17.7-19.7 GHz (s-E) and 27.5-29.5 GHz (E-s) by earth stations in motion communicating with geostationary space stations in the fixed-satellite service and take appropriate action, in accordance with Resolution 158 (WRC-15)
The meeting received 13 contributions, including the CEPT contribution, which mainly addressed the draft new AI1.5 Resolution. Work was indeed focussed on the draft new Resolution which includes three Annexes. Proposal from various contributions were discussed, text on resolves were revised and where agreement was not reached, options were included. Annex 1 contains provisions for ESIMs to protect space services in 27.5-29.5 GHz, Annex 2 contains provisions for Maritime and Aeronautical ESIMs to protect terrestrial services in 27.5-29.5 GHz. For the protection of terrestrial systems, options for Aeronautical ESIM pfd mask were reduced to two and 60-70 km protection distance was preferred for Maritime ESIM. Annex 3 contains guidelines to assist administrations in authorising ESIMs. CEPT proposal addressing elements of this annex were discussed and reflected elsewhere within the resolution. Views were expressed to delete Annex 3 but it was decided to maintain it within the Resolution unchanged as per the draft CPM text input to this meeting, since it was not discussed at any level during CPM19-2. The CPM text contains two Methods for this agenda item: Method A which proposes “No Change” to the Radio Regulation and Method B which CEPT supports.
Agenda item 1.6: to consider the development of a regulatory framework for non-GSO FSS satellite systems that may operate in the frequency bands 37.5-39.5 GHz (s-E), 39.5-42.5 GHz (s-E), 47.2-50.2 GHz (E-s) and 50.4-51.4 GHz (E-s), in accordance with Resolution 159 (WRC-15)
Ten contributions were received. The Methods in the CPM text were reduced from four to two. The Methods A, C and D were merged into Method A. Method B was suppressed. A new Method, based on the input to the CPM19-2 meeting was added to the CPM text as Method B.
Method A presents a regulatory and technical implementation to modify Article 22 of the Radio Regulation. Provisions are proposed to enable the operation of non-GSO systems, based upon the time allowance for the C/N value specified in the short-term performance objective and the decrease in spectral efficiency (for networks using adaptive code modulation) of the specified short-term and long-term performance objectives of the reference GSO links contained in the relevant ITU-R Recommendation under development.
Method B proposes to carry forward the studies to ensure the protection of GSO satellite networks under this agenda item to a new WRC‑23 agenda item towards the development of epfd limits.
The draft European Common Proposal is reflected in Method A, which has several options.
Agenda item 1.7: to study the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 (WRC-15)
Seven input documents were received and considered. CPM19-2 agreed in principle on three Methods to solve the Agenda Item:
- Method A proposes “No Change” to the Radio Regulations.
- Method B proposes an allocation of 1 MHz to the Space Operation Service (SOS) in the Earth-to-space direction, limited to non-GSO Short Duration satellite systems, in either 403-404 MHz (Method B1) or 404-405 MHz (Method B2), which is not subject to coordination under Section II of Article 9 of the Radio Regulations. It also proposes to use the existing SOS allocation in the frequency bands 137-138 MHz for the downlink.
- Method C proposes to use the existing SOS allocation in the frequency bands 137-138 MHz for the downlink and the 148-149.9 MHz band for the uplink and to provide appropriate associated regulatory provisions in the Radio Regulations for telecommand links of non-GSO Short Duration satellites. In order to comply with the requirement of non-GSO Short Duration missions for an allocation which is not subject to coordination, in the frequency band 148-149.9 MHz it is proposed to remove the reference to RR No. 9.21 in RR No. 5.218 and to not apply RR No. 9.11A.
At the moment CEPT has formulated two draft ECPs, based on Methods B and C, on which the discussion is still ongoing. An intense debate is envisaged at the WRC-19, in order to come to an acceptable conclusion for all stakeholders.
Agenda Item 1.8: to consider possible regulatory actions to support Global Maritime Distress Safety Systems (GMDSS) modernization and to support the introduction of additional satellite systems into the GMDSS, in accordance with Resolution 359 (Rev.WRC-15)
Ten contributions were received for this agenda item.
For Issue A (modernisation of GMDSS), three Methods are now included in the CPM Report:
- Method A1 proposes “No Change” to the Radio Regulation.
- Method A2 proposes frequencies to be used for medium frequency (MF) and high frequency (HF) navigational data (NAVDAT) systems, in support of GMDSS modernisation.
- Method A3 is a new Method similar to A2 with the following conditions:
- NAVDAT transmits only from coastal stations.
- Their usage is subject to agreement to be obtained from affected administration.
For Issue B (additional satellite systems as part of GMDSS), Methods in the CPM Report were reduced to four:
- Method B1 proposes to add the Mobile Satellite Service (MSS) band 1616-1626.5 MHz in both (Earth-to-space) and (space-to-Earth) directions in the RR Appendix 15 for use in GMDSS, while the status of space-to-Earth allocation stays secondary. Modifications to a number of provisions in Articles 5 and 33 are also proposed.
- Method B2, while supporting the addition of a new satellite system to GMDSS, expresses concerns on possible new constraints being placed on GSO MSS operations in the adjacent frequency band. It is divided into Method B2(a) and Method B2(b), which supplement Methods B1 and B4 respectively with additional regulatory text that would maintain the current regulatory status with respect to GSO MSS operations in the adjacent band.
- Method B3 proposes “No Change” to the Radio Regulation, as several issues have not been studied, including the regulatory status of the non-GSO MSS system and any potential adverse impact of any change to the regulatory status of in-band and adjacent systems or the apparent inconsistency and potential constraint of RR No. 5.368. Further, the compatibility issues related to the protection of the radio astronomy service have not been solved.
- Method B4 proposes an upgrade to the status of the MSS band 1621.35-1626.5 MHz from a secondary to a primary allocation to the MMSS (space-to-Earth) and its addition to the RR Appendix 15 for GMDSS. The status of all other allocations in the frequency band 1613.8-1626.5 MHz remains unchanged. Modifications to a number of provisions in RR Articles 5 and 33 are proposed, including RR No. 5.372 by introducing epfd and pfd threshold values for better protection of the radio astronomy service.
Agenda Item 1.9.1: to consider regulatory actions within the frequency band 156-162.05 MHz for autonomous maritime radio devices (AMRD) to protect the GMDSS and automatic identifications system (AIS), in accordance with Resolution 362 (WRC-15)
Seven input documents were considered by the meeting. The definition of autonomous maritime radio devices (AMRD), also agreed by IMO, was introduced in the CPM Report: AMRD are categorized as AMRD Group A, that enhance the safety of navigation, and AMRD Group B, that do not enhance the safety of navigation. Different Methods have been introduced to solve this agenda item.
For the operation of AMRD Group A, the single method (Method A) proposed in the CPM Report remained unchanged. This Method proposes to operate these of devices on DSC channel 70 (156.525 MHz) and the AIS channels, AIS1 (161.975 MHz) and AIS2 (162.025 MHz). The existing Method A was not changed by CPM19-2.
For the operation of AMRD Group B three Methods were already contained in the draft CPM Report. Based on the input contributions, Method B1 and B2 were amended, while Method B3 was replaced. Therefore the following three Methods are now proposed to solve this agenda item for AMRD Group B:
- Method B1 proposes channel 2006 (160.900 MHz) for AMRD group B using AIS technology. In addition this channel may also be used for future AIS-technology applications or systems on an experimental basis.
- Method B2 proposes channel 2006 (160.900 MHz) for AMRD group B using AIS technology as well. The channel 2006 may also be used for future AIS-technology applications or systems on an experimental basis. In addition this Method proposes channels 2078 (161.525 MHz), 2019 (161.550 MHz) and 2079 (161.575 MHz) for AMRD Group B using other technologies than AIS.
- Method B3 is new and proposes the same channels as the new Method B2 but it also foresees an e.i.r.p. power limitation into the relevant footnotes of RR Appendix 18. Channel 2006 is reserved for AMRD group B using AIS technology only.
The draft European Common Proposal is in reflected in Methods A and B2 for the two issues of this agenda item respectively.
Agenda Item 1.9.2: to consider possible regulatory actions, including spectrum allocations to the maritime mobile-satellite service (MMSS) Resolution 358 (WRC-12) to enable a new VHF data exchange system (VDES) satellite component in accordance with Resolution 360 (Rev. WRC-15)
The meeting received and considered nine contributions on this agenda item. The result of the work of CPM19-2 consist of six Methods proposed to resolve the agenda item:
- Method A proposes “No Change” to the Radio Regulations.
- Method B proposes primary allocations to the MMSS (Earth-to-space) and (space-to-Earth) using frequency plan 2 with coordination under RR No. 9.14 with two Options for the pfd-mask threshold. Option 1 is pdf-mask provided in Recommendation ITU-R M.2092, while Option 2 is pfd-mask provided in Annex 2 of Report ITU-R M.2435-0.
- Method C proposes secondary allocations to the MMSS (Earth-to-space) and (space-to-Earth) using frequency plan 2. Due to the secondary status of the new allocations, no coordination and pfd-mask is needed.
- Method D proposes secondary allocations to the MMSS (Earth-to-space) and (space-to-Earth) using frequency plan 2. A pfd limit for the (space-to-Earth) is introduced in a new footnote with two Options for the pfd-mask: Option 1 is the pfd mask provided in section 6.1.2.2.3.2 of Report ITU-R M.2435-0, while Option 2 the pfd mask provided in section 6.1.2.2.2 of Report ITU-R M.2435-0.
- Method E proposes secondary allocations to the MMSS (Earth-to-space) and (space-to-Earth) using frequency plan 2. Coordination is foreseen under RR No. 9.21.
- Method F proposes primary allocations to the MMSS (Earth-to-space) and (space-to-Earth) using frequency plan 3. Coordination is foreseen under RR No. 9.14 with pdf-mask provided in Recommendation ITU-R M.2092.
Method B with the pfd mask in Option 1 is in line with the latest preliminary CEPT position and draft ECP.
Agenda Item 1.10: to consider spectrum needs and regulatory provisions for the introduction and use of the Global Aeronautical Distress and Safety System (GADSS), in accordance with Resolution 426 (WRC-15);
The meeting considered six inputs on this agenda item dealing with Global Aeronautical Distress and Safety System (GADSS). Methods A and B which were already contained in the draft CPM Report were slightly updated and a new Method C was added, which proposes “No Change” to the Radio Regulation. Therefore, the current Methods to solve this agenda item are as follows :
- Method A: in order to facilitate its introduction, modification of the RR are proposed to include GADSS as a distress and safety communications system in RR Chapter VII – Distress and safety communications.
- Method B: in order to facilitate its introduction, modifications of the RR are proposed to include GADSS as a distress and safety communications system in RR Chapter VII – Distress and safety communications. In addition, the frequency bands used for GADSS, its systems, their technical characteristics and protection criteria shall be reflected in the relevant ITU-R Recommendations. Therefore, a new Resolution shall be developed, calling ICAO to provide to ITU-R this information and inviting ITU-R to develop appropriate Recommendations.
- Method C : the introduction of GADSS can be ensured by ICAO without any modifications of RR recognising that the studies within ICAO have determined that the GADSS requirements can be satisfied using existing systems operating within existing aeronautical frequency allocations and distress spectrum (e.g. 406.1 MHz).
Based on the output of CPM19-2, CPG PTC will seek a preliminary CEPT position on this agenda item.
Agenda item 1.11: to take necessary actions, as appropriate, to facilitate global or regional harmonized frequency bands to support railway radiocommunication systems between train and trackside (RSTT) within existing mobile service allocations, in accordance with Resolution 236 (WRC-15)
After the consideration of the six input documents received, the CPM Report contains three Methods to solve this agenda item including the “No Change” proposal (Method A). This Method is the one supported by CEPT. Furthermore, Method B proposes a new Resolution that specifies frequency ranges for RSTT, while Method C proposes a new Resolution which does not specify frequency ranges. Both Methods B and C refer to the most recent version of the ITU-R Recommendation dealing with frequencies for RSTT.
Agenda item 1.12: to consider possible global or regional harmonized frequency bands, to the maximum extent possible, for the implementation of evolving Intelligent Transport Systems (ITS) under existing mobile-service allocations, in accordance with Resolution 237 (WRC-15)
The meeting considered six documents. Three Methods are proposed to solve this agenda item. In addition to the “No Change” proposal of Method A, which is supported by CEPT, the CPM Report contains two other Methods: Method B proposes a new Resolution to encourage the use of the 5850-5925 MHz, or parts thereof, as global harmonized evolving ITS frequency bands and refers to Recommendation ITU-R M.2121 for other harmonized frequency band(s) for ITS; Method C proposes a new Resolution which only refers to the same Recommendation ITU-R M.2121.
Agenda item 1.13: to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15)
In total CPM19-2 considered 39 input documents on this agenda item.
All the CEPT Methods, alternatives and options are retained in the CPM text. There have been slight updates in some of the CEPT preferred text to reflect the discussions and to clarify the text.
There remains a difference of views on the measures to protect other services and hence multiple options are contained in the text. There was no agreement to include the additional summaries of the studies submitted at 45.5 - 47 GHz and 66 – 71 GHz by some CEPT countries: Hence different views have been included in the CPM text. On 26 GHz, the limit to protect EESS(passive) in the adjacent band has still to be resolved and many different values are contained in the CPM text.
Agenda item 1.14 : to consider, on the basis of ITU-R studies in accordance with Resolution 160 (WRC-15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed service allocations
The CPM text was finalised based on 17 input documents mainly to update the results of technical studies following last ITU-R Working Party 5C meeting in November 2018.
Discussions on this agenda item continued to be challenging with the following three main Methods further refined but retained in the CPM text as the meeting could not converge or narrow down the options at this stage.
- Method A proposes “No Change” to the Radio Regulations.
- Method B has different sub options depending on the band under consideration. The sub options provide for possible:
- Global identifications for HAPS at 6440- 6520 MHz (HAPS-ground), 27.9-28.2 GHz (HAPS-ground), 31-31.3 GHz (HAPS-ground and/or ground-HAPS) and 38-39.5 GHz (HAPS-ground and/or ground-HAPS) and modifications of some technical conditions for existing global HAPS identifications at 47.2-47.5 GHz / 47.9-48.2 GHz.
- Region 2 identifications for HAPS at 21.4-22 GHz (HAPS-ground) and Region 2 identifications for HAPS for different sub-bands/options (HAPS-ground and/or ground-HAPS) within the 24.25 – 27.5 GHz band
- Note – Apart from 47.2-47.5 GHz / 47.9-48.2 GHz bands, the above other global and Region 2 identifications options include a further sub option where HAPS cannot claim protection from existing services.
- Method C proposes the suppression of the existing HAPS identifications where technically found not to be feasible for HAPS operation.
The bands under consideration within CEPT and associated Options/Methods contained in the current draft ECP were further refined but retained in the CPM text providing further opportunity for discussion within CEPT.
Agenda item 1.15: to consider identification of frequency bands for use by administrations for the land mobile and fixed services applications operating in the frequency range 275-450 GHz
Ten contributions were received on this agenda item. The text of the CPM Report was significantly revised to properly include the outcomes of the latest studies conducted in ITU-R. Seven Methods are now proposed to solve this agenda item, as two new Methods were included. The Methods propose different footnotes for Fixed Service and Land Mobile Service applications in the band 275-450 GHz.
Agenda item 1.16: to consider issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between 5 150 MHz and 5925 MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 (WRC-15)
In total seven contributions were considered on whose basis the text in the CPM Report was consolidated and improved. Two new Methods A5 and A6 were added for the band 5150-5250 MHz, leading to six possible Methods to solve the agenda item in this band. This work reflects the slight difference between Methods A2 and A6 (dealing with OOB emissions) and Methods A4 and A5 (train, car&drone versus car only). Although there is no consensus in CEPT on this band at present some CEPT countries are supporting Method A4 or A5.
Methods for the 5725-5850 MHz band were also revised and amended. Method D2 was changed to only cover Regions 1 and 3 and Method D3 was changed to only include the option of a new national footnote. There is no consensus in CEPT on this band at present as there is a divergence of views between support for Method D1 (“No Change”) and Method D3 (to support allowing countries to sign up to “primary allocation to the mobile service by footnote” to reflect their current or intended national allocations).
In addition, there were no contributions received on the other bands under the agenda item, 5250–5350 MHz, 5350–5470 MHz and 5850–5925 MHz where “No Change” was the only proposal presented in the draft CPM text. CEPT has already early adopted ECPs for the “No Change” Methods proposed for each of these bands.
Agenda item 2: to examine the revised ITU-R Recommendations incorporated by reference in the Radio Regulations communicated by the Radiocommunication Assembly, in accordance with Resolution 28 (Rev.WRC-15), and to decide whether or not to update the corresponding references in the Radio Regulations, in accordance with the principles contained in Annex 1 to Resolution 27 (Rev.WRC-12)
Four documents were considered, including the Report of the Director of the Radiocommunication Bureau, listing the RR provisions and footnotes containing references to the ITU-R Recommendations or to the WRC Resolutions that contain references to ITU-R Recommendations.
The major discussion regarded the proposal from APT on merging Resolution 27 (Rev. WRC-12) and Resolution 28 (Rev. WRC-15) with the main aim of simplifying the Radio Regulations. However, it was stated that administrations need more time to properly consider proposed changes. This issue is related in fact to the ITU-R Recommendations incorporated into Radio Regulations and administrations wish to be sure that all principles are properly addressed in the final version of the merged Resolution.
Agenda item 4: in accordance with Resolution 95 (Rev.WRC-07), to review the Resolutions and Recommendations of previous conferences with a view to their possible revision, replacement or abrogation
Five inputs were considered including the Report of the Director of the Radiocommunication Bureau on general review of WARC/WRC Resolutions and Recommendations.
The main discussion regarded the proposal from APT for the revision of Resolution 95 (Rev. WRC-07). Subject of the discussion was the proposal to delete ”resolves 1“ of this Resolution and move it as part of the “considering”. Some administration were of the view that this modification, in conjunction with some proposed rephrasing of the text in the original Resolution 95, could slightly reduce the scope of the Resolution itself. Administration also need more time to consider the table consisting of proposed Course of Action for each of the Resolutions and Recommendations of previous Conferences.
Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary satellite orbit
In total this agenda item now consists of 11 separate issues, A-K, but it is rather 17 issues including 7 issues C1-C7 in Issue C. In general, the meeting made good progress keeping, and sometimes enforcing, the CEPT preferred Methods.
- Issue A - Bringing into use of frequency assignments to all non-GSO satellite systems, and consideration of a milestone-based approach for the deployment of non-GSO satellite systems in specific bands and services
The CPM discussed nine input contributions. For each of the two main topics, bringing into use and the milestone process, there is only one Method proposed but with several options for each topic. A new Method was introduced for the bringing into use, which consists of using a fixed 90 day period only for networks subject to coordination and not the others. The eight options on the milestone process remained unchanged. The Resolution was significantly modified and contains alternatives on different topics: transitional measures, treatment of the notices for modifications (if a milestone is not met), non-submission of deployment information, use of the same spacecraft for more than one filing, suspensions and post-milestone procedure. The question of tolerances requires further analysis. CEPT will continue to develop its position on this issue, especially on milestones and transitional measures.
- Issue B - Application of coordination arc in the Ka-band, to determine coordination requirements between FSS and other satellite services
Two contributions were received on this Issue. The “No Change” Method was suppressed as there is no longer any support for it, so change at WRC-19 is expected for this stable issue, only containing one single Methods that CEPT supports.
- Issue C - Issues for which consensus was achieved in ITU-R and a single Method has been identified
Two contributions were received, which regarded only Issues C4, C5 and C7. Some discussions took place and improvements were applied, but no critical changes were made to the seven different issues C1-C7.
- Issue D - Identification of those specific satellite networks and systems with which Coordination needs to be effected under RR Nos 9.12, 9.12A and 9.13
A contribution was received on this Issue. The “No Change” Method was suppressed as there is no longer any support for it, so change at WRC-19 is expected for this stable issue. The other two Methods remained unchanged.
- Issue E - Resolution related to RR Appendix 30B
The meeting considered two contributions . Modifications were made to the single Method in the CPM text, ensuring the decision not to bring back the earlier issues that CEPT opposed. This was raised and supported in CEPT coordination during the meeting.
- Issue F - Measures to facilitate entering new assignments into the RR Appendix 30B List
The meeting considered two contributions. Substantial changes were made to the CPM text with two new Methods added to Method F1 proposed by CEPT and the “No Change” Method. The new Method F2 is based on Method F1 but it allows new submissions of administrations to benefit from already agreed single entry C/I values; the provisions as contained in the current Appendix 30B to this effect would be retained. The new Method F3 is based on either Methods F1 or F2, but in addition, protection of the existing and operational additional systems recorded in the List prior to a specified date will be provided by applying criteria specified in Annex 4 of RR Appendix 30B.
- Issue G - Updating the reference situation for Regions 1 and 3 networks under RR Appendices 30 and 30A when provisionally recorded assignments are converted into definitive recorded assignments
Three contributions were considered and no modification was applied to CPM text. Therefore, there are still three Methods proposed for this Issue, with G1 being that supported by CEPT.
- Issue H (earlier issues H, I and L combined) - Modifications to RR Appendix 4 data items to be provided for non-geostationary satellite systems
Two contributions received on earlier Issues H, I and L. These issues targeted Appendix 4 data amendments with regards to non-GSO satellite filing parameters submitted to the Bureau. Hence they were appropriately merged and further improved into Issue H ensuring consistency, still only proposing one single merged Method.
- Issue I (earlier Issue M) - Modified regulatory procedure for non-GSO satellite systems with short-duration missions
Three contributions were submitted for this Issue. The CPM text was further developed, proposing a new draft Resolution and in addition a “No Change” Method was added to the CPM text. The new Resolution foresees changes in RR Articles 9 and 11.
- Issue J - Modification of Section 1, Annex 1 of RR Appendix 30 pfd limit
No contribution was received on this Issue. Therefore only editorial revisions were applied as appropriate to the CPM Report.
- Issue K - Difficulties for Part B examinations under § 4.1.12 or 4.2.16 of RR Appendices 30 and 30A and § 6.21 c) of RR Appendix 30B
One contribution was received on Issue K. No modifications were applied to the single Method supported by CEPT. The introductory text was improved in terms of balancing the text better with regards to the proposed changes in RR Appendix 30B and the changes in RR Appendices 30 and 30A.
Agenda item 8: to consider and take appropriate action on requests from administrations to delete their country footnotes or to have their country name deleted from footnotes, if no longer required, taking into account Resolution 26 (Rev.WRC-07)
This agenda item is not in the scope of the Conference Preparatory Meeting.
Agenda item 9.1: to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention
Issue 9.1.1: 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 1980-2010 MHz and 2170-2200 MHz where those frequency bands are shared by mobile service and the mobile-satellite service in different countries, in particular for the deployment of independent satellite and terrestrial components of IMT and to facilitate development of both the satellite and terrestrial components of IMT
Eight contributions were received on this issue. The CPM Report identifies four interference scenarios (A1, A2, B1, B2). Two different views exist on the basis of the results of the studies on these scenarios, which were updated during the meeting.
CEPT supports view 1 regarding Scenario A1, highlighting that there is currently no provision in the Radio Regulations to prevent interference from IMT base stations to IMT space stations and there is no coordination process between the administrations responsible for the mobile and mobile satellite services. Potential interference in the frequency band 1980‑2010 MHz from IMT terrestrial systems to the MSS satellite can be regulated establishing an e.i.r.p. limit.
The preliminary CEPT position is in line with view 1 on Scenario A2. Potential interference in the frequency band 2170-2200 MHz from IMT stations to MSS earth stations can be regulated by the current provisions on border coordination in Appendix 7 of the Radio Regulations. The same consideration applies for Scenario B1, as potential interference in the frequency band 1980‑2010 MHz from mobile earth stations to IMT base stations can be addressed by the current provisions on border coordination.
View 1 on Scenario B2 suggests that potential interference in the frequency band 2170-2200 MHz from MSS satellites to IMT terrestrial systems can be addressed by establishing a new coordination threshold pfd level, modifying Notes as appropriate. ECC PT1 will discuss if this current view can be supported by CEPT.
According to view 2 regulatory measures or changes to the Radio Regulations are outside the scope of this issue. Furthermore studies of possible technical and operational measures should be limited on ensuring coexistence and compatibility between the terrestrial component of IMT and the satellite component of IMT in the frequency bands 1980-2010 MHz and 2170-2200 MHz in adjacent geographical areas. CEPT has instead the view that the scope of this issue pertains to coexistence between the terrestrial and satellite components of IMT in different countries, which are not necessarily adjacent. Studies and measurements show, in fact, that there is a significant risk of interference between non-adjacent countries.
Issue 9.1.2: to conduct, in time for WRC-19, the appropriate regulatory and technical studies, with a view to ensuring the compatibility of IMT and BSS (sound) in the frequency band 1 452-1 492 MHz in Regions 1 and 3, taking into account IMT and BSS (sound) operational requirements
Three contributions were received from the Russian Federation, China and Japan. Overall, the approved CPM text contains nine Methods to satisfy the agenda item, identified in the text as “possible actions”.
The preliminary CEPT position is to support possible action 3. This action consists in inserting in the Radio Regulations a hard limit of pfd, which the Broadcast Satellite Service (BSS) shall not exceed on the territory of countries in Region 1 and Region 3 implementing IMT in the band 1452-1492 MHz. The countries whose territory would be protected by the pfd limit are those where the IMT is deployed, regardless the band is identified for IMT or not. A similar action has been proposed, but limiting the protection to the countries of Region 1 and Region 3 where the band is identified by IMT. This is labelled as possible action 4.
Issue 9.1.3: to study technical and operational issues and regulatory provisions for new non-geostationary-satellite orbit systems in the 3 700-4 200 MHz, 4 500-4 800 MHz, 5 925-6 4255 925-6 425 MHz and 6 725-7 025 MHz frequency bands allocated to the fixed-satellite service
No contribution was received on this issue. Therefore only editorial revisions were applied as appropriate to the CPM Report.
Issue 9.1.4: to conduct studies to identify any required technical and operational measures, in relation to stations on board sub-orbital vehicles, that could assist in avoiding harmful interference between radiocommunication services
Four contributions were considered for this issue. The text of the CPM Report was revised and updated, converging on a single view on regulatory issues on stations used for sub-orbital flights. These could be operated within the framework of existing radiocommunication services provided that incumbent services are not impacted. One single view was also agreed on the operations in space of sub-orbital vehicles. “No Change” to the Radio Regulations is proposed for WRC-19. Further operational, technical and regulatory issues may need to be addressed, which require continuing studies on the status of the station aboard sub-orbital vehicles and type of applications, through the appropriate mechanism and on the potential interference to be considered in the case of sub-orbital vehicles.
Issue 9.1.5: to consider the technical and regulatory impacts of referencing Recommendations ITU-R M.1638-1 and ITU-R M.1849-1 in Nos. 5.447F and 5.450A of the Radio Regulations
Five contributions were received by the meeting in total. Two new Methods have been added based on slight changes to Method B to replace the reference to existing ITU-R Recommendations in the footnote with reference to either ITU- R Resolution 229 or the footnote in the Radio Regulations which refers to Resolution 229. These two new Methods A and B have replaced all of the original Methods A, B, and C. Although the two Methods are very similar there is currently no consensus in CEPT on the final texts used in both Methods.
Issue 9.1.6: Resolution 958 (WRC-15) - Urgent studies required in preparation for WRC-19 - Studies concerning Wireless Power Transmission for electric vehicles (WPT for EV)
Two contributions were received by the meeting. The CPM text was updated to reflect the latest work and progress achieved by ITU-R Working Party 1B.
Issue 9.1.7: to examine whether there is a need for possible additional measures in order to limit uplink transmissions of terminals to those authorized terminals in accordance with No. 18.1, and the possible methods that will assist administrations in managing the unauthorized operation of earth station terminals deployed within its territory, as a tool to guide their national spectrum management programme, in accordance with Resolution ITU-R 64 (RA-15)
CPM19-2 considered three input documents and finalized the draft CPM Report on this issue. There are two Options identified in the CPM text: Option 1 is “No Change” to the Radio Regulations and is supported by CEPT, CITEL and APT. Option 2 regards a draft WRC-19 Resolution on unauthorized transmitting earth stations and is supported by the ASMG and some African countries.
Issue 9.1.8: to study the technical and operational aspects of radio networks and systems, as well as spectrum needed, including possible harmonized use of spectrum to support the implementation of narrowband and broadband machine-type communication infrastructures, in order to develop Recommendations, Reports and/or Handbooks, as appropriate, and to take appropriate actions within the ITU Radiocommunication Sector (ITU-R) scope of work
No contribution was received on this issue. Therefore only editorial revisions were applied as appropriate to the CPM text.
Issue 9.1.9: to conduct studies relating to spectrum needs and possible allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (Earth-to-space) GSO feeder links, Including the protection of the RAS, as appropriate
Six documents were received and considered. The meeting accepted to keep only one example of regulatory implementation, which is the allocation to the Fixed Satellite Service (FSS) in the frequency band 51.4–52.4 GHz under the conditions which are also identified in the draft European Common Proposal. The Option dealing with “No Change” to the Radio Regulation was deleted.
The existing regulatory text was mainly amended to introduce unwanted emissions limits for earth stations operating with FSS satellites located within 3.2° from the following orbital positions: 0º, 3.5ºE, 9.5ºE, 41.5ºE, 76ºE, 79ºE, 86.5ºE, 99.5ºE, 105ºE, 112ºE, 123.5ºE, 133ºE, 165.8ºE, 3.2ºW, 14.5ºW, 75ºW, and 137ºW. These limits are necessary to protect future projects on GSO EESS (passive). Such requirements were identified previously during the study cycle, but they were not included as part of the regulatory implementation during the last ITU-R Working Party 4A meeting. China proposed to CPM19-2 a rather complex mechanism for such protection but the meeting accepted the same limits previously proposed by CEPT with a small extension of the angles for applicability.
Agenda item 9.2: to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention on any difficulties or inconsistencies encountered in the application of the Radio Regulations
The Director of the Bureau presented the preliminary version of his Report to WRC-19 on the activities of the Radiocommunication Sector - Experience in the application of the Radio Regulatory Procedures and other related matters. This draft Report was noted, as its discussion is not in the scope of CPM. The final version of the document will be submitted to WRC-19, also taking into account the results of CPM19-2.
Agenda item 9.3: to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention on action in response to Resolution 80 (Rev.WRC-07)
No contribution was received and no discussion was held on this agenda item.
Agenda item 10: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention
The meeting considered ten documents on this agenda item, including a CEPT contribution.
The same approach as for the preparation of the previous Conference was adopted, underlying that it is not in the scope of the CPM to propose new future agenda items. The text of the CPM Report for the preliminary agenda items for WRC-23 already included in Resolution 810 (WRC-15) was updated and new descriptive text was added for proposals on GMDSS modernisation, Fixed satellite service at 37.5‑39.5 GHz and Review of 470-960 MHz in Region 1 (this latter based on the contribution from CEPT). Additional informative text was inserted on further proposals noting the suggestions for new future agenda items that were submitted by Member States for CPM. Links to websites of regional organisations were also added with a note that the information on the preparations on agenda item 10 can be found there.
