proposal for preliminary apt common proposals on WRC-19 agenda item 9.1 (issue 9.1.6, 9.1.7), 10
Agenda Item 9.1(Issue 9.1.6):
9.1.6 Issue 1) in the annex to Resolution 958 (WRC-15)
Urgent studies required in preparation for the 2019 World Radiocommunication Conference:
1) Studies concerning Wireless Power Transmission (WPT) for electric vehicles:
a) to assess the impact of WPT for electric vehicles on radiocommunication services;
b) to study suitable harmonized frequency ranges which would minimize the impact on radiocommunication services from WPT for electrical vehicles.
These studies should take into account that the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE) are in the process of approving standards intended for global and regional harmonization of WPT technologies for electric vehicles.
1. Background
The 4th Meeting of the APT Conference Preparatory Group for WRC-19 (APG19-4) was held from 7 to 12 January 2019 in Busan, Republic of Korea. The DG of AI 9.1 (Issue 9.1.6) of APG developed the preliminary views of WRC-19 AI 9.1 Issue 9.1.6. In APG19-5, the meeting will finalize APT views on WRC-19 AI 9.1 Issue 9.1.6 based on input contributions from APT Members and develop Preliminary APT Common Proposals (PACPs).
The Conference Preparatory Meeting for WRC-19 (CPM19-2) was held from 18 to 28 February 2019 in Geneva Switzerland. The CPM19-2 finalized the CPM text on WRC-19 AI 9.1 Issue 9.1.6 based on the input contributions.
As the responsible group of WRC-19 AI 9.1 Issue 9.1.6, ITU-R Working Party 1B (WP 1B) further worked on the WRC-19 Agenda Item 9.1 issue 9.1.6 at its June 2019 meeting. The New Report ITU-R SM.[WPT_EV_IMPACT] on “Assessment of impact of wireless power transmission for electric vehicle charging (WPT-EV) on radiocommunication services” was finalized by WP1B and approved by ITU-R Study Group 1 (SG 1).
The Revision of Recommendation ITU-R SM.2110-0 on “Frequency ranges for operation of non-beam wireless power transmission systems for electric vehicles” was finalized by ITU-R Working Party 1A (WP 1A) at its June 2019 meeting and adopted by ITU-R Study Group 1 (SG 1).
Views and Proposals
China is of the following views regarding to AI 9.1 Issue 9.1.6:
1) There is no need to change the Radio Regulations at WRC-19.
2) The globally and regionally harmonized frequency bands for WPT-EV applications refer to the most recent version of Recommendation ITU-R SM.2110.
3) All incumbent radiocommunication services must be adequately protected from harmful interference that may be generated by WPT-EV, both at the fundamental frequency and from spurious and out-of-band emissions.
Agenda Item 9.1 (issue9.1.7):
Issue 2) in the Annex to Resolution 958 (WRC-15)
2) Studies to examine:
a) 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;
b) 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).
1. Background
The Second Session of the Conference Preparatory Meeting for WRC-19 (CPM19-2) was held from 18 to 28 February 2019 in Geneva. The CPM19-2 meeting further discussed and revised the CPM Report on WRC-19 agenda item (AI) 9.1, issue 9.1.7. The study results of CPM19-2 Report on issue 9.1.7 are summarized as below:
With respect to issue 2a) in the Annex to Resolution 958 (WRC-15), two options have been identified:
- Option 1: no change to the Radio Regulations as current measures are sufficient. The Radio Regulations, specifically the provisions of Article 18, contain a clear and unambiguous requirement to operate an earth station only if duly authorized. New provisions in the Radio Regulations will not help address unlawfully operated earth stations.
- Option 2: to develop a new WRC Resolution to assist administrations with the application of RR No. 18.1.
With respect to Issue 2b) in Annex to Resolution 958 (WRC-15), one option has been identified:
- to provide necessary guidelines on satellite monitoring capabilities, along with possible revision and/or further development of ITU-R Reports or Handbooks to assist administrations with managing unauthorized operation of earth stations deployed within their territory, as a tool to guide their national spectrum management.
2. Views and Proposals
Issue 2a) in the Annex to Resolution 958 (WRC-15),
NOC.
Radio Regulations (WRC-15) Volumes 1 and 2
Reasons: The issue 2a) in the Annex to Resolution 958 (WRC-15) is sufficiently addressed in Article 18. Moreover, the Convention fully recognize the sovereign right of each State to regulate its telecommunication, so the issue 2a) can be addressed mainly by initiatives taken under the spectrum licensing and enforcement regimes, which are controlled by the spectrum management authority in a national level.
Issue 2b) in the Annex to Resolution 958 (WRC-15)
To further assist administrations in managing (identifying and geolocating) the unauthorized operation of earth stations deployed within their territory, the ITU-R needs to provide necessary guidelines on satellite monitoring capabilities, along with possible revision and further development of ITU-R Reports or Handbooks in this regard. These may provide guidance and support for administrations in managing the unauthorized operation of earth stations deployed within their territory and tools to guide their national spectrum management.
Reasons: The further development of ITU-R Reports or Handbooks can be considered, such as ITU-R SM.2182, SM.2424-0 and SM.2257-4, so as to provide guidance and support for administrations in managing the unauthorized operation of earth stations deployed within their territory.
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,
1. Background

Annex 1
Studies on frequency-related matters for identification of International Mobile Telecommunications in the frequency range of 5 925-7 125 MHz, or part thereof, for the
future development of International Mobile Telecommunications for 2020 and beyond
1. Background
Today’s world is powered by information. The opportunities created by Information and Communication Technology (ICT) development have been one of the main impacting factors on how society has been evolving in recent decades.
IMT-2020 technologies play an important role in the society as the new engine for the digital economy. The IMT systems support various usage scenarios. In addition to enhanced Mobile Broadband (eMBB), they also support massive Machine Type Communications (mMTC) and Ultra-Reliable Low-Latency Communications (URLLC) usage scenarios which include a wide range of applications. The applications driven by IMT-2020 have been expanding into new market segments such as smart grid, e-health, intelligent transport systems (ITS), traffic control and safety. With the pace of global commercialization of IMT-2020, the market demand for IMT services and applications will be increasing, in the meanwhile additional spectrum is required to facilitate new IMT-2020 application scenarios, to meet the increasing network capacities in coming years.
Over the past 20 years, World Radiocommunication Conferences have set up several agenda items for the identification and harmonization of IMT frequency bands. The latest is agenda item 1.13, seeking spectrum in the frequency range 24.25-86 GHz. All parties are looking forward to making significant progress on this agenda item at the Conference.
The millimeter wave frequency range and the middle frequency range are both playing vital roles to meet the spectrum needs for IMT. The millimeter wave frequency range is suitable to provide ultra-high capacity communication at hot spots in urban and densely populated areas, and the middle frequency range is needed to support new IMT-2020 applications which could deliver a very good balance between coverage and capacity needs. From a global perspective, the middle frequency range provides the most important frequency bands for the first wave of large scale IMT-2020 developments all over the world, especially the extended C-band (e.g. 3.4 - 3.6 GHz) and the 2.6 GHz band.
Thanks to the WRC-15 Agenda Item 1.1, available frequencies have been determined on a global, regional or national basis for IMT system in UHF, 1.4/1.5 GHz, 3.3-3.8 GHz and 4.8-4.99 GHz. But we have also witnessed that efforts are continuing to seek IMT spectrum in the low and medium frequency bands. At present, several frequency bands are proposed to be considered as possible IMT agenda item in WRC-23, including 470-694/698 MHz, 3 300/3 600-3 800 MHz, 3 800-4 200 MHz and 5 925/6 425-7 125 MHz, by administrations or regional groups.
The frequency range of 5 925-7 125 MHz may partially meet the future IMT spectrum needs in the middle frequency range, noting the trend that some of the incumbent services in this frequency band may migrate to higher frequency band in the future. In China, technical studies are under development to investigate possible interference to the existing radiocommunication systems in this band.
2. Proposal
China is considering the establishment of an agenda item for WRC-23 which aims at identifying frequency range for IMT in 5 925-7 125 MHz, or part thereof. The following attachment 1 contains a description of the proposal and attachment 2 contains draft text for a possible Resolution related to the proposed new agenda item.

|Subject: |
|Proposal for a new WRC-23 agenda item to consider IMT identification in the frequency range of 5 925-7 125 MHz, or part thereof, for the |
|future development of IMT 2020 and beyond. |
|Origin: China |
|Proposal: |
|To consider identification of IMT in the frequency band 5 925-7 125 MHz, or part thereof. |
|Background/reason: |
|Today’s world is powered by information. The opportunities created by Information and Communication Technology (ICT) development have been|
|one of the main impacting factors on how society has been evolving in recent decades. |
|IMT-2020 technologies play important roles in society as the new engine for the digital economy. The IMT systems support various usage |
|scenarios. In addition to enhanced Mobile Broadband (eMBB), they also support massive Machine Type Communications (mMTC) and |
|Ultra-Reliable Low-Latency Communications (URLLC) usage scenarios which include a wide range of applications. The applications driven by |
|IMT-2020 has been expanding into new market segments such as smart grid, e-health, intelligent transport systems (ITS), traffic control |
|and safety. With the pace of global commercialization of IMT-2020, the market demand for IMT services and applications will be increasing,|
|in the meantime additional spectrum is required to facilitate new IMT-2020 application scenarios, to provide the increasing network |
|capacities in coming years. |
|Over the past 20 years, World Radiocommunication Conferences have set up several agenda items for the identification and harmonization of |
|IMT frequency bands. The latest is agenda item 1.13, seeking spectrum in frequency range 24.25-86 GHz. All parties are looking forward to |
|making significant progress on this agenda item at the Conference. |
|The millimeter wave frequency range and the middle frequency range are both playing vital roles to meet the spectrum needs for IMT. The |
|millimeter wave frequency range is suitable to provide ultra-high capacity communication at hot spots in urban and densely populated |
|areas, and the middle frequency range is needed to support new IMT-2020 applications which could deliver a very good balance between |

|first wave of large scale IMT-2020 developments all over the world, especially the extended C-band (e.g. 3.4 - 3.6 GHz) and the 2.6 GHz |
|band. |
|Thanks to the WRC-15 agenda item 1.1, available frequencies have been determined on a global, regional or national basis for IMT system in|
|UHF, 1.4/1.5 GHz, 3.3-3.8 GHz and 4.8-4.99 GHz. And the efforts to seek spectrum for IMT usage in the low and medium frequency bands are |
|still continuing. At present, several frequency bands are proposed to be considered as possible IMT agenda item in WRC-23, including |
|470-694/698 MHz, 3 300/3 600-3 800 MHz, 3 800-4 200 MHz and 5 925/6 425-7 125 MHz, by administrations or regional groups. |
|The frequency range of 5 925-7 125 MHz may partially meet the future IMT spectrum needs in the middle frequency range, taken into account |
|that some incumbent services in this frequency band may migrate to higher frequency band in the future. Furthermore, IMT may achieve |
|feasibility of sharing with incumbent services in the same and adjacent frequency bands with the implementation of new radio |
|characteristics of IMT 2020 and beyond which reduce the interference to other services. Considering the above background, China proposes a|
|WRC-23 agenda item to conduct spectrum related studies to identify IMT in the frequency range of 5 925-7 125 MHz, or part thereof. |
|Radiocommunication Services concerned: |
|5 925-6 700 MHz Fixed Service, Fixed Satellite Service (Earth-to-space), Mobile Service |
|6 700-7 075 MHz Fixed Service, Fixed Satellite Service (Earth-to-space), Fixed Satellite Service (space-to-Earth), Mobile Service |
|7 075- 7145 MHz Fixed Service, Mobile Service |
|(adjacent services: TBD) |
|Indication of possible difficulties: |
|The proposed bands are widely used for terrestrial and space services on a co-primary basis. The coexistence of IMT and incumbent services|
|needs to be considered. |
|Previous/ongoing studies on the issue: |
|During the study period 2012-2015 and in preparation for WRC-15, the ITU-R conducted spectrum-related studies on IMT in accordance with |
|Resolution 238(WRC-15). |
|In the frequency band of 5925-6425 MHz, the result of sharing and compatibility studies for IMT and other services are demonstrated in the|
|Report ITU-R F.2326-0 (for the sharing studies with Fixed Service) and Report ITU-R F.2367 (for the sharing studies with FSS UL). |

|ITU-R Study Groups concerned: |
|SG5, SG4 and other groups |
|ITU resource implications, including financial implications (refer to CV 126): |

Annex 2
GMDSS Modernization and e-Navigation
1. Background
The Global Maritime Distress and Safety System (GMDSS) was adopted as part of the 1988 Amendments to the International Convention for the Safety of Life at Sea, 1974 (SOLAS). It was fully implemented in 1999. It has served the mariner and the maritime industry well since its inception, but some of the GMDSS technologies used have not reached their full potential, and some GMDSS functions could be performed by more modern technologies. IMO is in the process of GMDSS Modernization. The revision of SOLAS chapters III and IV, including related and consequential amendments to other existing instruments is still under discussion. IMO is also reviewing the systems applied to be recognized and used in GMDSS.
ITU-R conducts technical and operational studies on maritime and satellite issues in WRC-19 study cycle, aiming to address the frequency issues for the inclusion of additional GMDSS satellite system and MF and HF NAVDAT. The GMDSS modernization project needs to continue to support the needs of the e-navigation strategy.
BeiDou Message Service System (BDMSS) has been providing Message service for emergency communication since 2003, supporting aviation and maritime search and rescue operations. BDMSS uses the frequency bands of mobile satellite service (MSS) identified in ITU Radio Regulations, and currently provides the Message Service in Asia and Western Pacific area with the MSS payloads carried on several GSO satellites. The Maritime Safety Committee (MSC) of International Maritime Committee (IMO) considered the application for the recognition of BDMSS and use in GMDSS in MSC-99 in 2018. MSC referred the application to the Sub-Committee on Navigation, Communications and Search and Rescue (NCSR) for evaluation of the detailed information, to be provided to the sub-committee in due course, and authorized the sub-committee to invite International Mobile Satellite Organization (IMSO) to conduct the technical and operational assessment.
VDES Ranging-Mode (R-Mode) is a concept of a new terrestrial radio navigation system using timing information on existing maritime radio systems to provide GNSS independent positioning, navigation and timing (PNT). In emergency situations when GNSS is under interference or malfunctions, VDES R-Mode provides an alternative way for positioning by using timing information obtained from VDES coast stations. Therefore, VDES R-Mode could be considered a support for e-navigation strategy. The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) is developing VDES R-Mode technical standards and implementation plan.
China has developed an AIS Autonomous Positioning System (AAPS). In 2015, China finished system tests and successfully verified the theoretical feasibility and positioning precision of VDES R-Mode. The VDES R-Mode demonstration system project is implemented in Bohai Bay to further study the ASM R-Mode and VDE R-mode, aiming to develop systematic technical standards.
2. Views and Proposals
China invites ITU-R to consider GMDSS modernization process and activities in IMO, conduct studies and take regulatory actions on the inclusion of additional GMDSS satellite system and VDES R-Mode in the WRC-23 study cycle.

Annex 3
Consideration of regulatory provisions and possible frequency bands
for the stations on board suborbital vehicles
1. Background
With the increasing maturity of launch technology and significantly improving of success rate of recoverable commercial flight experiment, the application prospect of suborbital flight is getting wider and wider. However, it needs to be studied in many fields, such as definition, the demarcation between atmosphere and space, flight mode, tracking and control, safety assurance and so on. Radio communication plays a crucial role in every major phases of suborbital flight.
ITU-R calls for studies to meet the needs of radio applications for the stations on board suborbital vehicles in accordance with Resolution 763 (WRC-15), which was identified as the issue 9.1.4. ITU-R WP 5B，as the responsible group for issue 9.1.4, has carried out through discussion and studies on issues of suborbital space flight, suborbital vehicle and stations on board suborbital vehicle, etc., and developed a preliminary draft new report ITU-R M.[Suborbital Vehicles], which addresses, “Radiocommunications for suborbital vehicles”. The report provided various definitions in relation to suborbital vehicles and description of suborbital flight, and identified planned development that may require radio stations on board suborbital vehicles to use frequencies allocated to space and terrestrial services for the purpose of voice/data communications, navigation, surveillance, telemetry, tracking and command (TT&C), and safety of life and property. This report also provided a Doppler shift and link budget analysis for current aeronautical systems that may be used on suborbital vehicles, suborbital flight phases and selection of radiocommunication spectrum and so on.
The ITU-R studies suggest that, there is no requirement for any change to the Radio Regulations at WRC-19, and further operational, technical and regulatory issues may need to be addressed, which require continuing studies, on the status of the station aboard suborbital vehicles and type of applications, through the appropriate mechanism and on the potential interference to be considered with regards to radiocommunication systems operating on suborbital vehicles.
2. Discussions
The current regulatory provisions and procedures for terrestrial and space services may not be adequate for international recognition of the use of relevant frequency assignments by stations on board suborbital vehicles. China would like to propose that the following items should be included in the future studies:
← to identify the status of the station on board suborbital vehicles;
← to conduct further studies to determine spectrum requirements for communications on stations aboard suborbital vehicles in particular for voice/data communications, navigation, surveillance, telemetry, tracking and command (TT&C), safety of life and property, and so on.
← to conduct studies to identify appropriate radiocommunication services and corresponding frequency bands which can be used by stations on board suborbital vehicles; and
← to conduct studies regarding to the suborbital flight application scenarios and corresponding compatibility to avoid harmful interference between radiocommunication services.
3. Proposals
China proposes a new agenda item for WRC-23 to consider that further operational, technical and regulatory issues may need to be addressed, which require continuing studies, on the status of the station aboard suborbital vehicles and type of applications, and on the potential interference to be considered with regards to radiocommunication systems operating on suborbital vehicles. The detailed information and an example of the draft new Resolution are provided in Attachments 1 and 2 respectively.

Annex 4
views and proposals on proposed new agenda item
considering identification for use by high altitude platform station as IMT base stations (HIBS) in the frequency bands below 2.7 GHz identified for IMT
1 Background
Contributions (Doc. APG19-3/INP-54, APG19-4/INP-64) proposed to consider identification to use high altitude platform station as IMT base stations (HIBS) in the frequency bands below 2.7 GHz that have been already identified to IMT (Nos. 5.286AA, 5.295, 5.296A, 5.308A, 5.313A, 5.317A, 5.341A, 5.341B, 5.341C, 5.346, 5.346A, 5.384A and 5.388).
2 Discussion
2.1 In the frequency band 1 467-1 492 MHz
The frequency band 1 452-1 492 MHz is allocated to the fixed service (FS), mobile service (MS), broadcasting service (BS) and broadcasting-satellite service (BSS). Pursuant to Resolution 528 (Rev.WRC-15), in the interim period, broadcasting-satellite systems may only be introduced within the upper 25 MHz of this frequency band.
In China, the frequency band 1 467-1 492 MHz was allocated to BSS (sound) system. The satellite named ChinaSat-17 with L-BSS payload was launched in 2016, which could provide digital audio broadcasting with seamless coverage. While the broadcasting-satellite systems currently deployed in this band provide broadcasting service to cars, the new higher-powered satellites will leverage the propagation characteristics of the frequency mostly band to reach small handheld terminals, computer tablets and other mobile devices. This capability is important to support government and general population requirements in rural and remote areas that would otherwise not be serviced by the broadcasting service, as well as in more densely populated areas where terrestrial mobile services are well developed. The ability of BSS applications to reach many customers is very important for the public service.
2.2 In the frequency bands 1 980-2 010 MHz and 2 170-2200 MHz
As for the band 1 980-2 010 MHz/2 170-2 200 MHz, the issue of sharing and compatibility between satellite component and terrestrial component of IMT deployed in different countries has been raised and being studied by ITU-R WP 4C and WP 5D under WRC-19 agenda item 9.1 Issue 9.1.1. Preliminary study results show that harmful interference would occur between independent satellite component and terrestrial component of IMT not only for neighboring or adjacent countries but also for countries with boundaries thousands of kilometers far away. It could be envisaged that the sharing and compatibility situations between the satellite component of IMT and HAPS in these bands are also very complicated.
2.3 In the frequency band 2 300-2 400 MHz
The frequency band 2 300-2 400 MHz is allocated to the fixed service (FS), mobile service (MS), and radiolocation service (RLS) on co-primary basis in Region 2 and 3. Tremendous studies have been conducted during WRC-07 study cycle and the results show that the sharing and compatibility between MS and RLS are very complicated.
3 Views and Proposals
HAPS is capable to provide IMT services in rural and remote areas short of terrestrial telecommunication infrastructure, and as backup system to provide emergency communication service in case of other terrestrial communication system were failed.
It is also recognized that RR No.5.388A designated the frequency bands 1 885-1 980 MHz, 2 010-2 025 MHz and 2 110-2 170 MHz in Region 1 to HAPS as base stations to provide IMT in accordance with Resolution 221 (Rev.WRC-07), under the circumstance that HIBS 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. Therefore, spectrum needs for service link for HIBS should be studied in order to determine the candidate frequency bands taken into account the currently identified frequency bands.
China is of the views that the existing services and systems in the same frequency band and adjacent frequency band should be fully protected and supports not include the frequency bands 1467-1492MHz, 1 980-2 010 MHz, 2 170-2 200 MHz, and 2 300-2 400MHz in the possible WRC-23 agenda item.
Annex 5
views and proposals on proposed new agenda item for VHF
Space-Based Voice Communication Service
1. Background
In order to improve safety and efficiency in air traffic management (ATM) operations for airspace, the International Civil Aviation Organization (ICAO) is developing the separation minima standard (minimum distances aircraft need to fly apart from each other at all times to ensure safety), both seamless surveillance and communications are required, particularly for oceanic and remote areas.
The Singapore Flight Information Region is experiencing a lack of surveillance and communications coverage in the oceanic airspace. In November 2015, the International Telecommunications Union (ITU) World Radio communication Conference (WRC-15) allocated the frequency band 1,087.7 to 1,092.3MHz for reception of aircraft broadcasted ADS-B messages by space stations. For covering the surveillance gaps, the space-based ADS-B services can be readily integrated into Air Traffic Control (ATC) using iridium satellite constellation. For communication, the Datalink and Voice is the two kinds of solution to provide Direct Controller to Pilot Communication Service (DCPC), some regions (USA/ICAO Europe and North Atlantic) have improved the datalink solutions to support reduced separation minima over oceanic and remote areas. As the air navigation services provider for the Singapore FIR, CAAS has partnered with Gomspace AS (Gomspace) and Singapore Technologies Engineering Electronics (STEE) on a design study for space-based VHF Voice (relayed by Low Earth Orbit, LEO satellites or high altitude platform stations, HAPS) in conjunction with space-based ADS-B since 2017. The space-based VHF concept supported by ICAO/Asia and Pacific (APAC) Office/APANPIRG meeting, then CAAS presented a paper at ICAO Frequency Spectrum Management Panel (FSMP) Working Group (WG) Meeting #7. It was noted that space-based VHF would require International Telecommunications Union’s (ITU’s) allocation of VHF frequency spectrum for aeronautical mobile communications services between satellite and aircraft. Further to this, Singapore contributed an Input Document Paper to the 4th Meeting of the Asia Pacific Telecommunity (APT) Preparatory Group for WRC-19 (APG19-4) in January 2019 to highlight the concept of space-based VHF voice communications and the need for allocation of VHF frequency band for space-based VHF voice communications. This is to seek consideration of a future WRC Conference Agenda Item under Agenda Item 10 (AI 10) for such frequency allocation.
The summary of the Space-based VHF project simulation result：
1) Constellation of 64 clusters of platform at 600km altitude
2) Coverage of +/- 11 deg latitude
3) a couple of VHF frequencies as needed
The next plan of project:
1) If the study results are positive, it will be followed by a proof-of-concept (POC) demonstration in the end 2019 (depending on launch schedule). The POC will include launching of a few satellites equipped with the VHF relay stations to verify the expected performance.
2) ICAO Asia Pacific Regional Office will try to assign appropriate frequencies for POC so that verification tests could take place and has endorsed the operation requirements for space-based VHF voice services and correspondingly supported the ITU application process for the allocation of VHF frequency band for such use.
3) ICAO support a WRC-23 agenda item to address on ITU allocation of VHF frequency band for space-based VHF voice services purposes.
At present, one of the biggest constraints in ATC is the saturation of VHF voice communication channels in some air traffic congested areas of the world, maybe space-based VHF voice services will cause the worst negative influence on it. According to the Global Air Navigation Plan (GANP) introduced by ICAO, datalink is the better way to alleviate this saturation and congestion by providing an ATC CPDLC service, then there is a real benefit in reduced separation minima.
2. Preliminary Views
China is of the view that:
1) China does not oppose an agenda item to be established for space-based VHF voice communication services.
2) Space-based VHF voice communication services shall not cause harmful interference to, or claim protection from VHF ARNS or AMS (including ICAO and non-ICAO standardized), nor cause constraints to their use.
Annex 6
views and proposals on proposed new agenda item
to revise footnote No. 5.522B relating to enable the use of the band 18.6-18.8 GHz (space-to-Earth) by FSS non-GSO systems
with an apogee below 20 000 km
1. Background
WRC-2000 agenda item 1.17 was “to consider possible worldwide allocation for the Earth exploration-satellite (passive) and space research (passive) services in the band 18.6 18.8 GHz taking into account the results of ITU-R studies”.
It led to a set of various regulations, in particular RR No. 5.522A and 5.522B as well as relevant power limits given RR Nos. 21.5A and 21.16.2 to ensure coexistence between FS/FSS and EESS (passive). As far as FSS is concerned, the power limits in RR No. 21.16.2 were derived taking into account the known FSS characteristics at that time, and hence in particular the minimum apogee of 20 000 km given in RR No. 5.522B.
Frequency bands within the 17.7-19.7 GHz range are used extensively by EESS. They provide critical measurements for weather forecasting and studies of climate and environmental impacts. These measurements enable studies of clouds, precipitation, melting layer, snow, and ice. In addition, these measurements enable water vapour profiling and include measurements of sea surface temperatures, winds, and topography.
The 18.6-18.8 GHz band is one of the frequency bands utilized extensively for scientific uses, particularly for weather applications. Many passive remote sensing instruments operate in this band and more are planned for future deployment, it is therefore of vital interest to keep this important portion of the spectrum free of harmful interference. In particular, the 18 GHz channels are essential for all land and ocean surface data products generated from radiometer data, such as sea surface temperature, wind speed, water vapor, cloud liquid water, and rain rate.
Interference affecting spaceborne microwave radiometers in the 18.6-18.8 GHz band has been observed for several years and EESS operators have observed a trend of increasing interference. Interference reflected from Earth’s surface are contributing to the interference detected in the EESS passive sensors in this frequency band. Currently, ITU-R WP 7C is developing a new report on analysis of RFI caused to EESS (passive) sensors in the 18.6-18.8 GHz band (seen the WP 7C Chairman’s Report, 7C/379 Annex 7).
2. Preliminary Views
China is of the view that the existing EESS (passive) should be protected, and the revision of the footnote RR No. 5.522B to enable the use of the 18.6-18.8 GHz band (space-to-Earth) by FSS non-GSO systems with an apogee below 20 000 km could aggravate the interference into the EESS (passive) sensors in the 18.6-18.8 GHz band. Therefore, China does not support such revision to footnote RR No. 5.522B.
