ATTACHMENT A to FCC Public Notice DA 18-1017 Draft Proposals presented at October 1, 2018 Meeting of the World Radiocommunication Conference Advisory Committee Terrestrial Services Document WAC/063 (01.10.18) WRC-19 Agenda Item 1.13 (47.2 – 50.2 GHz) IWG-2 members were not able to reach consensus on a proposal for WRC-19 Agenda Item 1.13 regarding the identification of frequency bands for the future development of International Mobile Telecommunications (IMT), in accordance with Resolution 238 (WRC-15) for the frequency range 47.2-50.2 GHz. The views on the appropriate regulatory changes the FCC should support are provided. View A is supported by: Boeing, Echostar, Inmarsat, Viasat, Lockheed Martin, SES. View B is supported by: AT&T, Cisco, CTIA, Ericsson, Global Mobile Suppliers Association (GSA), GSMA, Intel Corporation, Samsung, Sprint Corporation, T-Mobile, and Verizon. VIEW A View A: View A proposes no change to the Radio Regulations in the 48.2-50.2 GHz band, taking into account the identification of this band in ITU-R Region 2 for high density applications in the fixed-satellite service (HDSSS), the United States Spectrum Frontiers decision to provide core uplink spectrum in the fixed-satellite service (FSS) in this band, and the critical requirement for core spectrum for regional and international GSO and NGSO satellite operations.. Finding that broadband services delivered over satellite networks could play a useful role in bringing the benefits of broadband to more Americans, the United States has reserved the HDFSS identifications at 48.2-50.2 GHz and 40-42 GHz for exclusive FSS use. Economies of scale in both earth station and spacecraft design require that satellite operators be able to rely on the availability of HDFSS identifications throughout the ITU Regions to which they apply. Given the current state of satellite technology and the ubiquitous nature of HDFSS user terminals, these systems need access to spectrum where satellite end user devices can operate and be freely deployed without risk of interference to or from other services. An identification for IMT in the 48.2-50.2 GHz frequency band (and the corresponding 40-42 GHz downlink band) for IMT is incompatible with this objective because IMT and HDFSS applications will be ubiquitous, at locations unknowable in advance, making the interference case for both services uncertain. View A suggests that an IMT identification may be made at 47.2-48.2 GHz (with the exception of the 47.5-47.9 GHz segment in ITU Region 1) under certain conditions. The United States did provide for terrestrial use of the 47.2-48.2 GHz band in the Spectrum Frontiers order, while making provisions for the co-primary fixed-satellite service to continue to use the band. The supporters of View A view continued use of this the 47.2-48.2 GHz band as vital to the FSS, and notes that View B contains no provisions to facilitate that continued use. Any IMT identification in the 47.2-48.2 GHz frequency band should be conditioned upon: 1) A total radiated power (TRP) limit and antenna electrical and mechanical downtilt standards for IMT base stations, which is necessary to avoid interference into FSS space stations at 47.2-48.2 GHz, 2) Mechanisms to permit continued access to the 47.2-48.2 GHz band by FSS Earth stations, and 3) Avoidance of IMT use of the space-to-Earth HDFSS identification at 47.5-47.9 GHz in ITU Region 1. ATTACHMENT TO VIEW A: UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.13 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) Background Information: Both terrestrial and satellite broadband services play a crucial role in providing access to businesses and consumers worldwide and will be critical components of 5G networks. For continuity, resiliency and broad connectivity solutions, satellite broadband is an indispensable part of the broadband environment. Because of increased demand for satellite broadband services, there is a need for additional spectrum being made available to support its growing user base. Broadband satellite systems require access to unencumbered uplink spectrum to operate widely deployed transmitting user terminals. To satisfy this minimum requirement, ITU Radio Regulation No. 5.516B identifies 2 GHz of uplink spectrum for high-density fixed-satellite service (HDFSS) operations in ITU Region 2 in the 48.2-50.2 GHz fixed-satellite service (FSS) band (Earth-to-space), paired with the 40-42 GHz FSS band (space-to-Earth) (see Resolution 143 (Rev. WRC-07)). Ubiquitously-deployed IMT operations may not be compatible with ubiquitously-deployed co-frequency/co-coverage HDFSS or other FSS operations. As FSS operations are conducted on a regional and worldwide basis by both geostationary-satellite orbit (GSO) and non-GSO networks and systems, and access to core spectrum facilitates such operations, the 48.2-50.2 GHz band should remain unencumbered for FSS use worldwide. HDFSS operations provide access to a wide range of broadband telecommunication applications, including broadband services and machine-to-machine (M2M) communications, both independently and in complement with other telecommunication systems. Growth in the satellite M2M market is expected to reach US$2.9 billion by 2026, driven by 6.8 million in-service terminals. Alan Weissberger, IEEE Communication Society Blog, NSR: Satellite IoT market forecast at $2.9B by 2026 (Oct. 1, 2017) (available at http://techblog.comsoc.org/2017/10/01/nsr-satellite-iot-market-forecast-at-2-9b-by-2026/). These terminals will be deployed over urban, suburban and rural areas of large geographical extent, and the practicability of techniques to successfully manage co-frequency sharing with ubiquitous terrestrial services, such as IMT, has not been demonstrated. HDFSS systems require flexible, rapid and ubiquitous deployment of large numbers of cost-optimized earth stations employing small antennas and having common technical characteristics. The identification of bands for HDFSS facilitates its implementation and maximizes global/regional access and economies of scale noting the different bands identified for HDFSS in different regions as per No. 5.516B. Given the current state of satellite technology, these systems would need access to spectrum where satellite end user devices can operate and be freely deployed uplink user terminals across in a given country. To this end, the band 48.2-50.2 GHz worldwide should not be identified for ubiquitously-deployed IMT use. Additionally, there is a recognition that IMT will require access to the 47.2-48.2 GHz portion of the 47.2-50.2 GHz band for ubiquitously-deployed terminals. Such use would be under the condition that use of the mobile service allocation by IMT does not preclude the use of this frequency band by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. FSS earth stations are planning to use the 47.2-48.2 GHz band, along with other co-primary services, so it is necessary to provide technical and operational conditions on the IMT designation in the mobile service, in the form of an associated Resolution, to assure that FSS use is not effectively or otherwise precluded. Further, no change is proposed to the 47.5-47.9 GHz segment in ITU Region 1, due to the regional HDFSS allocation in the space-to-Earth direction.

The value of 14 dBW/200 MHz is proposed with a definition of TRP as “the sum of all power radiated by an antenna connected to a transmitter.” This level applies for all foreseen modes of operation (i.e. maximum in-band power, electrical pointing, carrier configurations). A different definition may necessitate a different value. 1b that, when deploying outdoor IMT base stations in the frequency band 47.2-48.2 GHz, administrations shall ensure that each antenna transmits only with the main beam pointing below the horizon and that the transmitting antenna shall have mechanical and electrical pointing below the horizon; 2 to ensure that, when considering, nationally or regionally, the spectrum to be used for IMT, due attention is paid to the need for spectrum for earth stations that could be deployed in a ubiquitous manner (i.e. small user earth stations) and for earth stations that could be coordinated (i.e. gateways) in both downlink and uplink directions in the 47.2-48.2 GHz band, taking into account spectrum identified for the HDFSS as per No. 5.516B, invites ITUR to develop an ITUR Recommendation to assist administrations in ensuring the protection of existing and future FSS earth stations in the frequency band 47.2-48.2 GHz from IMT deployments in neighbouring countries.

The current state of satellite technology requires access to spectrum where satellite end user devices can operate and be freely deployed without constraints caused by ubiquitous terrestrial services in the same band. ______________________________ VIEW B VIEW B: Introduction View B proposes an identification to the terrestrial component of IMT for the 47.2-50.2 GHz frequency bands in all three Regions. View B is supported by AT&T, Cisco, CTIA, Ericsson, Global Mobile Suppliers Association (GSA), GSMA, Intel Corporation, Samsung, Sprint Corporation, T-Mobile, and Verizon. Incredible technological innovation has enabled the use of higher frequency bands (e.g. millimeter wave) to help meet the ever-increasing demand for mobile broadband.  As a global spectrum policy leader, the FCC led the US to be the first country in the world to make high band spectrum available for 5G with other leading countries also making spectrum available for 5G. Similarly, the FCC decision to make 47.2-48.2 GHz available for Upper Microwave Flexible Use Service (UMFUS) is anticipated to stimulate demand in nearby spectrum, with other countries and regions beginning to explore the possibility of 5G use in adjacent spectrum. The 47.2-50.2 GHz frequency bands are allocated to the Fixed, Fixed Satellite, and Mobile Services on a co-primary basis in all three Regions. With respect to high density applications in the Fixed Satellite Service under No. 5516B, it is important to note that Regions 1 and 2 utilize different portions of the 47.2-50.2 GHz bands for these applications and that the spectrum for high density applications in Region 3 is in frequency bands other than 47.2-50.2 GHz. Furthermore, No. 5516B explicitly states that “This identification does not preclude the use of these bands by other fixed-satellite service applications or by other services to which these bands are allocated on a co-primary basis and does not establish priority in these Radio Regulations among users of the bands.” As part of WRC-19 agenda item 1.13 preparations, ITU-R Task Group 5/1 carried out extensive sharing and compatibility studies between the Fixed Satellite Service and IMT: these studies show that sharing in the 47.2-50.2 GHz frequency bands is feasible with a large interference margin. For example, the results for aggregate emissions from IMT into a GSO FSS space stations found the calculated I/N ranged from -37 to -30 dB: even worst case values for each IMT transmitter and no clutter loss found an I/N of -19 dB. For the non-GSO case, results ranged from I/N of -21.7 dB to -37 dB. With regards to protection of passive services in the adjacent band 50.2-50.4 GHz included in RR 5.340, no conditions are necessary in Resolution 750 since RR 5.340.1 clearly states that “The allocation to the Earth exploration-satellite service (passive) and the space research service (passive) in the band 50.2-50.4 GHz should not impose undue constraints on the use of the adjacent bands by the primary allocated services in those bands” Given the potential for increased economies of scale, the co-primary allocation to the Mobile Service, the regulatory status of this spectrum in the Radio Regulations (including the fact that the frequency band is not identified for high density applications in the 3 Regions), and the favourable results of sharing studies, the above-signed support View B with an identification to the terrestrial component of IMT in 47.2-50.2 GHz. ATTACHMENT TO VIEW B: UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.13 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) Background Information: Mobile broadband plays an increasingly crucial role in providing access to businesses and consumers worldwide. According to International Telecommunications Union (ITU) statistics, “Mobile-broadband subscriptions have grown more than 20% annually in the last five years and are expected to reach 4.3 billion globally by end 2017.” while “Mobile-broadband prices as a percentage of GNI per capita halved between 2013 and 2016 worldwide. ICT Facts and Figures 2017, p 4 and 5. See: https://www.itu.int/en/ITU-D/Statistics/Documents/facts/ICTFactsFigures2017.pdf Incredible technological innovation has enabled the use of higher frequency bands (e.g. mmWave) to help meet the ever-increasing demand for mobile broadband.  The 47.2-50.2 GHz frequency range is shared on a co-primary basis between the Fixed, Fixed Satellite and Mobile Services in all three Regions. The Fixed Service allocation includes a global identification for high-altitude platform stations (“HAPS”) at 47.2-47.5 GHz paired with 47.9-48.2 GHz (No. 5.552A). As part of the preparations for WRC-19 agenda item 1.13, ITU-R carried out extensive sharing and compatibility studies between IMT and the Fixed Satellite Service: these studies show that sharing between the terrestrial component of IMT and the Fixed Satellite Service is feasible with a large interference margin in the 47.2-50.2 GHz frequency range. The ITU-R Working Party 5C is studying sharing and compatibility of broadband HAPS with IMT for deployment of HAPS in this band with greater rain fade mitigation. The harmonization of spectrum for mobile broadband provide benefits to consumers and businesses through economies of scale and global roaming. However, Administrations may be unable to make spectrum available in the exact same frequency bands due to different existing uses and priorities. Therefore, in order to achieve the benefits of harmonization while allowing regulators the flexibility to assign spectrum within this range for domestic use as appropriate, an identification for IMT is proposed in the 47.2-50.2 GHz frequency range. A global identification for IMT in 47.2-50.2 GHz would allow each country/region to assign spectrum for IMT consistent with their domestic use and priorities, while still facilitating the benefits of economies of scale for businesses and consumers. Finally, there is no need for a WRC Resolution specifying technical and operational constraints on IMT to be associated with this proposed identification for IMT. Operational characteristics that are used by cellular providers, such as base station downtilt, that change on time scales needed to minimize intra- and inter-cell interference and also guarantee quality of service should not be encoded in the Radio Regulations. Similarly, with regards to the use of the band by high density applications in the FSS (No. 5.561B), no condition is required to achieve a balance of spectrum between FSS and IMT since this is a national matter and hence should not be included in any WRC Resolution. With regards to protection of passive services in the adjacent band 50.2-50.4 GHz included in No. 5.340, no changes to Resolution 750 are necessary since No. 5.340.1 clearly states that “The allocation to the Earth exploration-satellite service (passive) and the space research service (passive) in the band 50.2-50.4 GHz should not impose undue constraints on the use of the adjacent bands by the primary allocated services in those bands.” Proposals: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/1.13/1 40-47.5 GHz Allocation to services Region 1 Region 2 Region 3 47.2-47.5 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 MOBILE ADD 5.H113 5.552A 47.5-51.4 GHz Allocation to services Region 1 Region 2 Region 3 47.5-47.9 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 (space-to-Earth) 5.516B 5.554A MOBILE ADD 5.H113 47.5-47.9 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 MOBILE ADD 5.H113 47.9-48.2 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 MOBILE ADD 5.H113 5.552A 48.2-48.54 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 (space-to-Earth) 5.516B 5.554A 5.555B MOBILE ADD 5.H113 48.2-50.2 FIXED FIXED-SATELLITE (Earth-to-space) 5.516B 5.338A 5.552 MOBILE ADD 5.H113 48.54-49.44 FIXED FIXED-SATELLITE (Earth-to-space) 5.552 MOBILE ADD 5.H113 5.149 5.340 5.555 49.44-50.2 FIXED FIXED-SATELLITE (Earth-to-space) 5.338A 5.552 (space-to-Earth) 5.516B 5.554A 5.555B MOBILE ADD 5.H113 5.149 5.340 5.555 Reasons: As studies show sharing with other services operating in 47.2-50.2 GHz is feasible, these modifications provide an identification for IMT in the frequency range 47.2 to 50.2 GHz. This facilitates harmonized worldwide bands for IMT, which are highly desirable in order to achieve global roaming and the benefits of economies of scale. ADD USA/1.13/2 5.H113 The frequency band 47.2-50.2 GHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT). This identification does not preclude the use of this frequency band by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. Reasons: Harmonized worldwide bands for IMT enable global roaming and the benefits of economies of scale as the same user equipment can be used to serve the global market. _____________________________ Document WAC/064 (01.10.18) UNITED STATES OF AMERICA DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE 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) Background Information: The frequency band 66-71 GHz is allocated on the primary basis to inter-satellite, mobile-satellite radionavigation-satellite, mobile and radionavigation services. To date, very few, studies have been carried out to confirm IMT compatibility with some of the existing or planned networks operating under these allocations as part of the preparations for World Radiocommunication Conference 2019 (WRC-19) agenda item 1.13. License-exempt access to spectrum plays a critical role in providing connectivity for users worldwide. In recognition of this fact, many countries have designated this frequency band for licence-exempt 5G (e.g. WiGig) technologies. In the United States, while issuing rules to facilitate 5G, the FCC decided to maintain the unlicensed use of the 64-71 GHz band. Similarly, the European Union’s Radio Spectrum Policy Group stated, “general authorised frequency use can be an important breeding ground for innovation and contributes towards a dynamic market environment. The application of a general authorisation regime is foreseen in the 66-71 GHz band which could be an important band for 5G.” See RSPG Second Opinion on 5G Networks In many administration, the use of the 66-71 GHz band by applications in the Mobile service is regulated on a license-exempt, technology neutral basis, similar to the 2.4 GHz and 5 GHz bands. Under this approach regulators adopted rules for unlicensed devices that are designed to prevent harmful interference to authorized radio services through limits on transmitter power and spurious emissions, while industry has developed standards within the framework of these rules, generally with the intention of ensuring cooperative sharing of the spectrum by unlicensed devices. Such approach resulted in numerous benefits and innovative products for consumers. There is significant risk that identification of the 66-71 GHz band for IMT at WRC-19 would disrupt this dynamic by implying a different regulatory regime for one Mobile service application (i.e., IMT) over all others. It is also important to recognize the nascent state of 5G ecosystem in the 60-70 GHz frequency range. Multi-gigabit devices are just beginning to be introduced into the market. Growing demand has been driving technological developments towards much higher throughputs (20 Gbps and higher), which can be attained only with corresponding spectrum capacity. In ITU-R significant efforts are underway to advance implementation of Multiple Gigabit Wireless Systems (MGWS) systems in 66-71 GHz frequency band. See ITU-R Doc. 5-1/32, Recommendation ITU-R M.2003-2 and Report ITUR M.2227 It is difficult to predict how technologies, spectrum needs, market demands and other factors will evolve in this frequency range. In the absence of this understanding, an international treaty-level regulatory action on the 66-71 GHz band at WRC-19 under agenda item 1.13 would be premature and counterproductive. Identifying 66-71 GHz for IMT would do little to achieve international harmonization.

View C is supported by: Lockheed Martin View D is supported by: Echostar, Inmarsat, Viasat, SES VIEW A VIEW A: WAC Members Facebook and Loon support View A (IWG-2 78rev4 1-14) and recommend it to the WAC and the FCC as the basis for reconciling a U.S. Proposal on HAPS (AI 1.14) for CITEL PCC.II. View A incorporates many requests from members of both the Mobile and Fixed Satellite sector, reflecting the last version considered by IWG-2, after many weeks of meetings and calls where edits were proposed and accepted. Background: The U.S. has long been a leader in innovation. Advances in avionics, solar energy components and lightweight composite aircraft parts have fueled global interest in high-altitude unmanned vehicles for a range of applications, including delivery of broadband. Proponents of High Altitude Platform Stations (“HAPS”), signatories of View A, support the identification of sufficient spectrum for broadband HAPS, to extend broadband Internet access to underserved and unserved communities. The U.S. has also long recognized the importance of broadband for economic growth. To be a leader in our Region and globally, the U.S. must also recognize the importance of broadband for our neighbors. At the last CITEL PCC.II meeting, a Draft Inter-American Proposal (“DIAP”) was adopted by Brazil, the Bahamas and Ecuador that recognized the role HAPS can play in extending broadband networks at a more affordable cost point. HAPS is a station, akin to a tower in the sky, and not a service, so any operator licensed by its spectrum regulator can use this tool to extend their network, whether they are a Mobile or Satellite operator. This is a tool that should be embraced by all sectors. The HAPS DIAP, which proposes HAPS identifications in the 24.25-27.5 GHz and 38-39.5 GHz bands, was adopted on the basis of studies that Brazil’s spectrum regulator, ANATEL, undertook on HAPS and IMT 2020 co-existence. Brazil also led the formation of a DIAP for identifying IMT 2020 under agenda item 1.13 in the same bands - 24.25-27.5 GHz and 38.0-39.5 GHz bands. Their studies determined that Mobile and HAPS fixed links can co-exist. The U.S. should propose identifications that cover these bands, to maintain leadership on this promising new technology. Moreover, at the last CITEL PCC.II, Mexico also proposed a HAPS identification in the 21.4-22 GHz band. To lead on HAPS for our Region, the U.S. should propose identifications that build upon these two proposals, and identify 21.4-22 GHz, 24.25-27.5 GHz, and 38-39.5 GHz for HAPS. Discussion: The U.S. was the lead sponsor of HAPS at WRC-15, identifying that as a priority at the last Conference. The agenda item passed due to developing country support that the US encouraged, both in our Region and in Africa. The Resolution adopting agenda item 1.14 (Res. 160) noted that the existing HAPS identifications were not adopted in reference to today’s broadband capabilities. Res. 160 identified two new bands to be studied in Region 2 (21.4-22 GHz and 24.25-27.5 GHz) for broadband HAPS, one band to be studied on a global basis (38-39.5 GHz), and the possible modification of the existing HAPS identifications to facilitate broadband. HAPS proponents have sought identifications in bands where mobile operators plan to deploy IMT 2020 (5G) precisely in order to benefit consumers with economies of scale in broadband equipment that can be used both in 5G and HAPS, such as chips, antenna components, etc., to make HAPS backhaul affordable in costly areas where 3G and 4G has not yet been deployed. It is expected that HAPS can further accelerate the growth of 5G by providing backhaul in underserved and unserved communities. In the last two and a half years since studies began under AI 1.14, global interest in HAPS has increased dramatically. Major national operators are considering HAPS projects, as have many aerospace companies. To enable co-existence with existing services, HAPS proponents propose ubiquitous pfd levels to protect Fixed and Mobile services from HAPS downlink emissions. To protect Fixed Satellite operations, proponents propose that HAPS links operate in the opposite direction to space stations where possible. For the protection of science services, EIRP limits and coordination among administrations can ensure protection. Finally, to protect passive science services in the bands adjacent to proposed HAPS identifications, OOBE limits for both HAPS platforms and ground stations are proposed in View A (#78rev4). View A proposes that HAPS be identified in the 21 GHz, 24.25-27.5 GHz, and 38-39.5 GHz bands to both reflect U.S. industry views and align with our CITEL neighbors. View A also proposes that the single global existing HAPS identification in 47/48 GHz be modified for gateway use and better rain mitigation, recognizing that other bands would be available for user equipment uplinks downlinks. Lastly, View A proposes that the existing HAPS identification in 28/31 GHz band be modified for worldwide use, both with protections added for other co-primary services. Together, these identifications amount to what the ITU expert working party found was needed for broadband HAPS, about 4 GHz in most markets. ATTACHMENT TO VIEW A: UNITED STATES OF AMERICA DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE 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. BACKGROUND No. 1.66A of the ITU Radio Regulations define a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25-27.5 GHz bands in Region 2 exclusively. Currently there are 3 spectrum bands identified for HAPS in the fixed services. These are: - 47.2–47.5 GHz and 47.9 48.2 GHz, - 27.9-28.2 GHz (HAPS-ground) and 31.0-31.3 GHz (ground-HAPS) - 6 440–6 520 MHz (HAPS-ground) and 6 560-6 640 MHz (ground-HAPS). However, spectrum needs of next-generation HAPS cannot be accommodated within these designations due to either geographical restrictions or technical limitations which impairs their operation. The global designations for HAPS links (which is in the 47.2-47.5 GHz band fixed-service allocation paired with the 47.9-48.2 GHz band fixed-service allocation) suffers from the effects of rain fade attenuation that severely limit service provision over high-precipitation geographies. The remaining 2 available bands (27.9-28.2 GHz paired with the frequency band 31.0-31.3 GHz, and 6440-6 520 MHz paired with 6 560-6 640 MHz) have been identified by a limited number of countries, none of which is within ITU Region 2. The ITU-R developed a Preliminary New Draft Recommendation (PDNR) assessing spectrum needs for broadband HAPS at an approximate 4 GHz aggregate capacity. The following proposals encourage the designation of HAPS in the fixed service allocations on a co-primary basis to facilitate investment in and deployment of HAPS, while ensuring protection to systems of other services allocated in the band as well as not providing priority to HAPS over other uses within the services allocated on a primary basis. BROADBAND HAPS APPLICATIONS Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer connectivity over large areas in a reliable and cost-effective way, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen: · Wide-area coverage: A single platform will be able to serve footprints larger than 100 km in diameter, and recent technological advances in the development of optical inter-HAPS links now allow the deployment of multiple linked HAPS, in fleets that can cover whole nations. · Low cost: The cost of operating stratospheric platforms is projected to be significantly lower than other connectivity solutions in many areas, while mass production of the aircraft will significantly lower upfront capital expenditure for deployment. · Reach: HAPS platforms will operate at around 20 km above ground, which reduces their vulnerability to weather conditions that may affect service, provides large coverage areas and avoids interference caused by physical obstacles. · Rapid deployment and flexibility: It will be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration. · Geographical reach: HAPS that use the architecture of solar platforms can also provide connectivity where it is impossible to deploy terrestrial infrastructure: remote sites on land or sea. · Environmentally friendly: HAPS can run exclusively on solar power for long periods, connecting people with almost no environmental impact. Spectrum harmonization and utilization is facilitated by common worldwide designations. International regulatory flexibility can enable improvements in global connectivity by encouraging national regulators to permit operation of higher-speed Internet access services over new, complementary platforms, while ensuring protection of existing services. Additionally, harmonization of spectrum promotes economies of scale and commonality of equipment. Broadband HAPS can also be used for: · Response to natural disasters. · Fire detection, monitoring, and firefighting. · Law enforcement with communication needs across local actors and regional headquarters. · Resource exploration missions for communication between exploration teams and regional home base. SHARING STUDIES A number of administrations and technology proponents have conducted compatibility studies to assess coexistence between HAPS and incumbent and proposed systems and services (including WRC-19 Agenda Items 1.6 and 1.13).  A power-flux density (PFD) threshold would be used to ensure the protection of the fixed and mobile services from downlink emissions by HAPS platforms (HAPS-to-ground), which if exceeded would require coordination with neighboring administrations and their explicit agreement. This PFD ensures that the signal level produced by HAPS systems at the location of fixed and mobile service stations will not cause interference. Protection from uplink emissions by HAPS ground stations with other stations of the fixed service or mobile service could be ensured through coordination at the national level, based on the relatively short separation distances (and other mitigation techniques) provided by the studies. The protection of FSS satellite networks on a co-channel basis appears to be feasible if the frequency bands used by a HAPS network is transmitting in an opposite direction from that of the FSS satellite network (i.e., satellite Earth-to-space with HAPS-to-ground, and satellite space-to-Earth with ground-to-HAPS). In these cases, some studies suggest that satellite stations can be protected from HAPS-to-ground emissions, while relatively short separation distances can be used to protect Earth stations from ground-to-HAPS emissions through station coordination amongst administrations or usual link planning procedures used at a national level. In the case of national level coordination, the use of mitigation techniques and/or geographical separation could be used to enable deployments by either service. For the protection of science services (EESS, SRS, RAS), radiated power limits and coordination amongst administrations could be used to ensure the protection of these services. The receiving earth station for EESS and SRS can be protected through coordination. In the case of science services operating in adjacent bands to HAPS, specific limits on out-of-band emissions for both HAPS platforms and ground stations can be used to ensure their protection. 1.

SUP USA/1.14/19 5.543A Draft new Resolution for the 27.9-28.2 and 31-31.3 GHz bands ADD USA/1.14/20 DRAFT NEW RESOLUTION [E114] (WRC19) Use of the bands 27.9-28.2 GHz and 31-31.3 GHz by high altitude platform stations in the fixed service The World Radiocommunication Conference (Sharm el-Sheikh, 2019), considering a) that WRC-15 considered that there is a need for greater broadband connectivity in underserved communities and in rural and remote areas, that current technologies can be used to deliver broadband applications by high-altitude platform stations (HAPS), which can provide broadband connectivity and disaster recovery communications with minimal ground network infrastructure; b) that WRC-15 decided to study additional spectrum needs for fixed HAPS links to provide broadband connectivity, including the existing designations in the 27.9-28.2 GHz and the 31-31.3 GHz bands, recognizing that the existing HAPS designations were established without reference to today’s broadband capabilities; c) that HAPS can provide broadband connectivity with minimal ground network infrastructure; d) that Recommendation ITU-R P.618, “Propagation data and prediction methods required for the design of Earth-space telecommunication systems”, should be used to determine rain fade attenuation from HAPS platforms; e) that Recommendation ITU-R P.452, “Prediction procedure for the evaluation of interference between stations on the surface of the Earth at frequencies above about 0.1 GHz”, should be used to determine the propagation loss in the ground path from HAPS ground stations; f) that Recommendation ITU-R SF.1395, “Minimum propagation attenuation due to atmospheric gases for use in frequency sharing studies between the fixed-satellite service and the fixed service”, should be used to determine the gaseous attenuation; g) that Recommendation ITU-R P.2108, “Prediction of Clutter Loss”, should be used to determine the clutter loss, recognizing a) that HAPS is defined in No. 1.66A of the Radio Regulations as a station located on an object at an altitude of 20-50 km and at a specified, nominal, fixed point relative to the Earth, and is subject to No. 4.23, resolves 1 that for the purpose of protecting the fixed wireless systems in neighboring administrations in the band 27.9-28.2 GHz, the power flux density level per HAPS platform station at the surface of the Earth in neighboring administrations shall not exceed the following pfd mask in dBW/m2/MHz, under clear sky condition, without the explicit agreement from the affected administration: pfdmaxEl=3×El-140 for El≤10° pfdmaxEl=0.57×El-115.7 for 10° 29° -42.5 dB(W/40 kHz) b. For any ESIM that does not meet the conditions 1.a. above, it shall not transmit within 2,179 km of any current or future non-GSO MSS feeder link earth station with parameters as described in Attachment 1 to this Annex. ATTACHMENT 1 TO ANNEX 1B Analysis for ESIM exclusion zones to protect non-GSO MSS feeder link systems Agenda Item 1.5 compatibility studies between ESIMs and feeder links for the non-GSO MSS have not been finalized and need further study due to the complexity of the dynamic interference environment and disagreement on parameters used for the studies to determine the full potential for interference. Reference to these ongoing studies can be found in Annex 15 to Document 4A/826 (Working Document Towards a Preliminary Draft New Report ITU-R S.[ESIM]). Table 1 below provides a static analysis that demonstrates the potential interference that an ESIM can cause to a representative non-GSO MSS feeder link system. Table 1: Static ESIM interference analysis ESIM parameters have been duplicated from the ongoing described in the Working Document referenced above. ESIM uplink transmissions have the potential to generate interference levels that exceed non-GSO MSS feeder link satellite receiver noise floor by over 38 dB. Thus, 38.4 dB of antenna discrimination is required just to reduce the amount of interference to the level of the satellite receiver noise floor. This antenna discrimination could be applied to the ESIM antenna (if not pointing directly at the non-GSO MSS satellite) and/or the non-GSO MSS satellite antenna. A simplified example of this is shown in Figure 1. Figure 1: ESIM interference to non-GSO satellite feeder link geometry Since there can always be a scenario in which the non-GSO MSS satellite moves through the main beam of an ESIM transmission, the antenna discrimination applied to the ESIM antenna for this case is 0 dBi, leaving all of the 38.4 dB of discrimination to be applied to the non-GSO MSS satellite receive antenna. Again referencing the above Working Document study, the HIBLEO-2FL satellite receive antenna pattern is modeled using Recommendation ITU-R S.465-5, which assumes an off-axis gain described by the following equation: G = 32 – 25 log ϕ dBi, for ϕmin ≤ ϕ < 48°. For the peak satellite antenna gain of 30.1 dBi, an antenna discrimination of 38.4 dBi results in an absolute off-axis antenna gain, G, of -8.3 dBi. From the equation above, to meet this value of G, the off-axis angle, ϕ, is found to be equal to 41 degrees. As shown in Figure 1, for the HIBLEO-2FL satellite at its minimum elevation angle of 5 degrees, and for an ESIM near the Earth’s surface, the ESIM would need to be 2179 km from the HIBLEO-2FL feeder link earth station and be at the 41 degree off-axis angle from the perspective of the HIBLEO-2FL satellite antenna. For the ESIM parameters assumed above, this is the maximum distance at which an ESIM could be from the HIBLEO-2FL feeder link earth station and produce an interference level equal to the satellite receiver noise floor (I/N = 0 dB). The particular geometry for this scenario could exist at high latitude regions in which both the HIBLEO-2FL feeder link is at its minimum elevation angle and in alignment with the ESIM link to a geostationary satellite low on the horizon. This static analysis does not consider likelihood of interference events or percentage of time that interference levels thresholds are exceeded. Factors that would impact this result include specific locations of the non-GSO MSS feeder link earth station, ESIM and GSO satellite, the number of ESIMs transmitting near the feeder link earth station, the transmission parameters of these ESIMs including the duty cycles at which they transmit, and the specific non-GSO MSS feeder link protection criteria. However, since these factors are still being considered and debated within ITU-R Working Party 4A, a static analysis as provided above is needed to bound the ESIM interference problem. As a comparison, it’s worth noting that the referenced Working Document includes a simulated analysis, for a different geographic location and for a protection criterion I/N value slightly different than the I/N = 0 dB case considered here. That analysis yields a worst-case separation distance of 1455 km. The static analysis provided here indicates that harmful interference from ESIMs to non-GSO MSS feeder link communications could occur even at separation distances greater than 2,000 km. Simulated results based on non-GSO MSS feeder link geographic locations and ESIM-supported GSO networks could produce different separation distances, but no resolution of those simulation parameters has been agreed at this time.

There are currently no defined technical provisions for sharing between non-GSO systems and GSO networks in the 50/40 GHz frequency bands. Moreover, there are no existing mechanisms in the RR establishing coordination procedures applicable to non-GSO systems operating within the FSS allocations in frequency bands in the 37.5 to 51.4 GHz range, such as application of RR No. 9.12. To address these issues, and the uncertainty they create among potential operators of non-GSO FSS satellite systems in this 50/40 GHz range, WRC-15 established agenda item 1.6 for WRC-19: “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 (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space), in accordance with Resolution 159 (WRC-15).” Resolution 159 (WRC-15) invites administrations to contribute to the specified ITU-R studies of technical, operational issues and regulatory provisions for non-GSO fixed-satellite services satellite systems in these frequency bands while ensuring protection of GSO satellite networks in the FSS, MSS and BSS. Additionally, as part of the regulatory framework to be developed for non-GSO satellites, resolves 4 of Resolution 159 (WRC-15) calls for the protection of Earth exploration-satellite service (EESS (passive) in the 50.2-50.4 GHz band and the possible revision of Resolution 750 (Rev. WRC-15) ensuring the protection of the EESS from non-GSO FSS transmissions. Although resolves 4 calls for the consideration of aggregate FSS interference effects, recognizing i) states that potential revisions to the protection of passive services will be impractical to apply to GSO FSS networks, either filed, planned or operational. This point recognized by WRC-15, which has been carefully considered by the ITU membership since then, remains true today that new GSO FSS limits would be impractical to implement and create an undue constraint to the FSS. Non-GSO FSS systems in the 50/40 GHz band can be utilized to unlock a new and promising source of global broadband communications. Recent advances in satellite design, launch service capabilities and user terminal technology make it feasible to provide global satellite broadband services. Thanks to these recent technological advances, next-generation non-GSO satellite systems are currently being developed. These systems can greatly enhance the efficient use of existing FSS spectrum by using next-generation satellite and earth station technology. The benefits of such non-GSO satellite systems include providing worldwide connectivity and high-quality communication services to users in all geographic settings, be they urban, rural or remote, and offer tools for definitively addressing the longstanding broadband gap. Developing a regulatory framework in the 50/40 GHz band will provide regulatory certainty to allow non-GSO satellite systems to efficiently operate in these existing FSS frequency bands. ITU-R studies have concluded that sharing between non-GSO systems and protection of GSO satellite networks is possible in these frequency bands. ITU-R Working Party 4A has also been working on the development of a new Recommendation to identify means and a methodology to define a protection criteria for sharing by FSS systems in the 50/40 GHz bands. The methodology in this Recommendation and proposed protection criteria considers both the short term performance objectives and long term time-average bandwidth efficiency to enable use of these frequency bands by non-GSO FSS systems that will ensure protection of GSO networks. ITU-R studies have confirmed that the application of the procedures in the new Recommendation allows for flexibility in the design and operation of non-GSO systems, while fully protecting GSO operations, therefore significantly enhancing spectrum efficiency of the 50/40 GHz bands. All four methods identified by the ITU-R as potential methods to satisfy WRC-19 AI 1.6 propose a similar approach to address issues related to non-GSO and GSO sharing, including a regulatory framework based upon single entry and aggregate allowances of unavailability and time-average bandwidth efficiency and a Resolution to track aggregate effects from multiple non-GSO systems to ensure GSO protection. All four methods also propose a modification to RR Article 9 to address coordination between non-GSO FSS systems in the 50/40 GHz bands. Regarding protections of EESS (passive) and modifications to Resolution 750 (Rev. WRC-15), the four methods present a range of options for protection of EESS (passive) systems in the 50.2-50.4 GHz bands from non-GSO earth station transmissions. The proposals below present a regulatory solution for providing certainty and technical provisions to allow for sharing between non-GSO FSS systems and for protection of co-frequency GSO networks and adjacent-band EESS (passive) systems under WRC-19 AI 1.6. The proposals have been developed based on the results of ITU-R studies called for in Resolution 159 (WRC-15), and identify a methodology to allow for maximum spectrum efficiency for non-GSO FSS systems, while protecting operations of GSO networks from operations of non-GSO FSS systems. This proposal also provides a regulatory solution to ensure that aggregate emissions from operating non-GSO FSS systems do not exceed aggregate protection requirements of GSO networks. Regarding the EESS (passive) protection from non-GSO FSS transmissions, this proposal contains limits of unwanted emission power in the adjacent band 50.2-50.4 GHz. After careful consideration of the unwanted emission power from GSO stations into EESS (passive), this proposal retains the current GSO limits to ensure the current operating environment is maintained. This proposal tracks closely with Method A in the draft CPM Report.

SD missions might provide a useful alternative means for satisfying some scientific and commercial space requirements purposes. Thus, the objective of WRC-19 Agenda Item 1.7 is to better quantify the spectrum requirements for NGSO satellites with short duration (SD) missions, and to determine what if any suitable revisions to the Radio Regulations may be needed to adequately accommodate these types of satellite missions. WRC-19 Agenda Item 1.7 invites studies to accommodate spectrum requirements for TT&C in the space operation service, below 1 GHz, for NGSO satellites with short duration missions (SD-NGSO) in existing bands not subject to No. 9.21. The lead group for the conduct of the studies is ITU-R WP-7B. Thus far, studies have concluded that the Space Operations Service (SOS) applications are not able to co-exist with current usage. Consequently, the study efforts have shifted to considering the feasibility of possible new spectrum allocation(s) or an upgrade of an existing allocations within the frequency ranges 150.05-174 MHz and 400.15-420 MHz (e.g., so that RR No. 9.21 does not apply). Compatibility studies have shown that current technical and operational characteristics of SD-NGSO may not protect global maritime distress and safety service (GMDSS) frequencies for space, coast, ship and aircraft station frequencies between 156-163 MHz, nor frequencies used for the safety of life COSPAS/SARSAT system in the band 406-406.1 MHz. One Administration has suggested that studies should consider using existing SOS allocations in the 137-138 MHz and 148-149.9 MHz bands for SD-NGSO, however no studies considered to date by ITU-R WP-7B have assessed the compatibility of that concept with aeronautical mobile (R) service systems operating in adjacent allocated spectrum which is used heavily worldwide for all aspects of air traffic control in all airspace. Considering the impact to safety services, no regulatory method has been considered for possible solutions to remove RR No. 9.21 for existing space operation service Earth-to-space ground stations to ensure incumbent protection from harmful interference. In addition, technical studies for both methods proposing a new SOS (Earth-to-space) allocation between 403-405 MHz has shown varying conclusions regarding the feasibility of sharing. Finally, studies have raised concern about using the existing SOS (s-E) allocation in the 137-138 MHz due to possible impacts on aeronautical systems operating below 137 MHz. The frequency band 117.975 – 137 MHz is allocated worldwide to the AM(R)S service and is used to transmit Air Traffic Control (ATC) and Airline Operational Control (AOC) communications in all phases of flight and in all airspace. The upper portion of this frequency band, 136-137 MHz, is primarily used for air-ground digital communications to supplement existing voice communications. The highest assignable channel, 136.975 MHz, is the Very High Frequency Data Link Mode 2 (VDL M2) Common Signaling Channel (CSC) as specified in Annex 10 to the Convention on International Civil Aviation Volume III 6.1.2.3. One administration has suggested using existing SOS allocations in the 137-138 MHz band for the SD-NGSO downlink. Assuming the characteristics in the DN Report for SD-NGSO uplink and downlink, the SOS emissions below 137 MHz will be too high to protect the AM(R)S service. Similarly, proposed use of the existing SOS (E-s) allocation in the 148-149.9 MHz band using the stated characteristics will result in required separation distances that would not be supportable operationally. The Draft CPM (Method C) proposes thresholds for coordination similar to those for MSS in 137-138 MHz, which is specified in Annex 1 of Appendix 5 of the RR and removal of No. 9.21 in RR No. 5.218. The coordination for MSS (space-to-Earth) in 137-138 MHz is done under RR No. 9.11A, requiring meeting a pfd threshold on the earth’s surface for coordination with terrestrial services. SOS ground station assignments in the 148-149.9 MHz band are required to be coordinated under RR No. 9.21, which was deemed not suitable for SD-NGSO in Resolution 658 (WRC-15). However, no studies considered to date by ITU-R WP-7B have assessed the feasibility of implementing SD mission spectrum utilization under the ‘Method C’ option with adequate means for ensuring protection of heavily used AM(R)S systems operating adjacent bands. PRELIMINARY VIEW WP-7B should continue studies examining the feasibility of accommodating SD in bands below 1 GHz while ensuring protection of incumbent and adjacent band services. WP 7B should continue collaborating with other WPs to facilitate studies for WRC-19. ___________________ Regulatory Issues Document WAC/071 (01.10.18) UNITED STATES OF AMERICA DRAFT PROPOSAL FOR WRC-19 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.WRC07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationarysatellite orbit; Issue B – Application of coordination arc in the Ka-band, to determine coordination requirements between the FSS and other satellite services Background Information: WRC-19 agenda item 7, Issue B, proposes the introduction of the coordination arc with a value of 8 degrees as coordination criteria between fixed-satellite service (FSS) and mobile-satellite service (MSS) systems and between MSS systems, in the frequency bands 29.5-30 GHz (Earth-to-space)/19.7-20.2 GHz (space-to-Earth) in all 3 Regions. The introduction of an 8 degree coordination arc would serve as a substitution of the existing coordination trigger of ΔT/T > 6%. Currently, when determining whether coordination under RR No. 9.7 is required between FSS vs FSS satellite networks, a coordination arc of 8º is the coordination criteria applied in the frequency bands 29.5-30 GHz (Earth-to-space)/19.7-20.2 GHz (space-to-Earth). Results of ITU-R studies show that earth station terminals used in the MSS and FSS for these frequency bands are quite similar. Therefore, it could be considered that the coordination arc that currently triggers coordination between FSS systems could be applied to trigger coordination between MSS and FSS systems and between MSS systems. Introduction of the coordination arc of 8 degrees would reduce the number of Administrations identified for coordination, thereby reducing the number of coordination processes and resulting in a reduction of required resources in Administrations, operators, and Bureau. Administrations will continue to have the possibility to request application of RR No. 9.41 for inclusion of additional affected satellite networks, taking into account the ΔT/T > 6% criteria. In this proposal, it is proposed to implement the modifications to the Radio Regulations in accordance with Method B.

The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. Pursuant to RR No. 11.46, the Bureau allows Notifying Administrations six months to resubmit their notified frequency assignments, which were returned due to an unfavorable finding with respect to RR Nos. 11.32, 11.32A or 11.33. Any notification resubmitted beyond six months is considered as a new notification with a new date of receipt and would be subject to cost recovery fees. However, neither RR No. 11.46 nor any other provision in the Radio Regulations requires the Bureau to send a reminder to the Notifying Administration at any point during the six-month period. If the Notifying administration resubmits the notice to the Bureau beyond the required six-month period, the Bureau assigns a new date of receipt and reviews whether the notice complies with the period in RR No. 11.44.1 or RR No. 11.43A and takes the appropriate action. In the case that a notice resubmitted beyond the six-month deadline is receivable, cost recovery fees would be required for the resubmitted assignments. Addressing this lack of a reminder would be beneficial to Administrations who may have experienced difficulties receiving or addressing the Bureau’s return of notice and the need to ensure that frequency assignments that are in use are properly recorded in the Master Register. A single method has been identified to address this issue. It would be considered advantageous to Notifying Administrations if the Bureau sends a reminder of the option to resubmit returned frequency assignments under RR No. 11.37 or 11.38. Modification of RR No. 11.46 requiring the Bureau to remind the Notifying Administration of the six-month deadline would aid Administrations who may have had difficulties in receiving the communication of returned frequency assignments. Proposal: ARTICLE 11 Notification and recording of frequency assignments1, 2, 3, 4, 5, 6, 7, 8    (WRC15) MOD USA/AI7(C5)/1 11.46 In applying the provisions of this Article, any resubmitted notice which is received by the Bureau more than six months after the date on which the original notice was returned by the Bureau shall be considered to be a new notification with a new date of receiptX. For frequency assignments to a space station, should the new date of receipt of such a notice not comply with the period specified in No. 11.44.1 or No. 11.43A, as appropriate, the notice shall be returned to the notifying administration in the case of No. 11.44.1, and the notice shall be examined as a new notice of a change in the characteristics of an assignment already recorded with a new date of receipt in the case of No. 11.43A.     (WRC19) Reasons: To include a reference to a footnote provision requiring the Bureau to send a reminder two months prior to the end of the six-month period referred to in No. 11.46. ADD USA/AI7(C5)/2 _______________ X 11.46.1 If the resubmitted notice is not received by the Bureau within four months from the date on which the original notice was returned by the Bureau, the Bureau shall shall promptly send a reminder to the notifying administration. Reasons: To implement the requirement for reminders during the six-month period and reduce the risk of a resubmission beyond the end six-month period referred to in No. 11.46. ____________________ Document WAC/073 (01.10.18) UNITED STATES OF AMERICA DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE 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.WRC07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationarysatellite orbit; 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 Background Information: At the 2012 World Radiocommunication Conference (WRC-12) modifications to RR No. 9.36.2 to Article 9 of the Radio Regulations were adopted to decrease the administrative workload related to the identification of the satellite networks, systems and earth stations, as applicable, with which coordination needs to be effected under RR Nos. 9.7, 9.7A and 9.7B. The Bureau now publishes a “definitive list” of those networks, systems and earth stations with which coordination under RR Nos. 9.7, 9.7A and 9.7B needs to be effected once a coordination request (a new one or a modification to an existing one, as appropriate) for a satellite network or system is processed. Such a list is published in the relevant Special Section of the BR International Frequency Information Circular (BR IFIC). However, in the cases of coordination under RR Nos. 9.12, 9.12A and 9.13, the Bureau does not publish a list of the satellite networks or systems potentially affected to complement the list of administrations potentially affected by incoming satellite networks or systems that they do provide. Bearing in mind that, according to RR No. 9.36.1, the list of administrations identified for coordination under RR Nos. 9.12, 9.12A and 9.13 is only for information purposes, each of those potentially affected administrations needs to carry out the following tasks: 1 Identify, together with each of its operators, those GSO networks and non-GSO systems that may be affected by the new satellite system requesting coordination; 2 Compile, in case the administration is responsible for more than one operator, a comprehensive list covering all the GSO networks and non-GSO systems with which coordination is required; 3 Transmit to the administration having filed a CR/C (a new one or a modification to an existing one, as appropriate) and to the Bureau its comments on or disagreement to the request for coordination pursuant to RR No. 9.52. The above process could be simplified if a pre-compiled list of satellite networks or systems considered as potentially affected would be available, for information purposes only, in the cases of coordination under RR Nos. 9.12, 9.12A and 9.13 as it is currently for the cases of RR Nos. 9.7, 9.7A and 9.7B in the CR/C Special Section. In this proposal, it is proposed to implement the modifications to the Radio Regulations in accordance with Method D2. Proposal: ARTICLE 9 Procedure for effecting coordination with or obtaining agreement of other administrations1, 2, 3, 4, 5, 6, 7, 8, 9    (WRC15) Section II − Procedure for effecting coordination12, 13 Sub-Section IIA − Requirement and request for coordination MOD USA/AI7(D)/1 20 9.36.1 In the case of coordination under Nos. 9.12, 9.12A and 9.13, as appropriate, the Bureau shall also identify the satellite networks or systems with which coordination may need to be effected. The list of administrations identified by the Bureau under Nos. 9.11 to 9.14 and 9.21 and the list of satellite networks or systems identified by the Bureau under Nos. 9.12, 9.12A and 9.13 are only for information purposes, to help administrations comply with this procedure. (WRC-19) Reasons: This modification is required in order to have the list of potentially affected satellite networks or systems published in addition to the list of administrations. Sub-Section IIC − Action upon a request for coordination MOD USA/AI7(B)/2 9.52C For coordination requests under Nos. 9.11 to 9.14 and 9.21, an administration not responding under No. 9.52 within the same fourmonth period shall be regarded as unaffected and, in the cases of Nos. 9.11 to 9.14, the provisions of Nos. 9.48 and 9.49 shall apply. Furthermore, for coordination under Nos. 9.12, 9.12A and 9.13, any satellite network or system identified under No. 9.36.1 but not confirmed in the response provided by administrations under No. 9.52 within the same four-month period shall be regarded as unaffected and the provisions of Nos. 9.48 and 9.49 shall also apply. (WRC-19) Reasons: This modification is required to indicate the consequence for not identifying satellite networks or systems in the response provided under No. 9.52. MOD USA/AI7(D)/3 9.53A Upon expiry of the deadline for comments in respect of a coordination request under Nos. 9.11 to 9.14 and 9.21, the Bureau shall, according to its records, publish a Special Section, indicating the list of administrations having submitted their disagreement and the list of satellite networks or systems upon which their disagreement is based, as appropriate, or other comments within the regulatory deadline.     (WRC19) Reasons: This modification is required in order to have the definitive list of affected satellite networks or systems published in addition to the list of administrations. ____________________
