This agenda item relates to consideration of spectrum needs and regulatory provisions for the introduction and use of the Global Aeronautical Distress and Safety System (GADSS), in accordance with Resolution 426 [COM6/11] (WRC-15).

GADSS is intended to address the timely identification and location of an aircraft during all phases of flight as well as distress and emergency situations and to use existing and new applications to support search and rescue and flight data retrieval.

In particular:

1. to study terrestrial and satellite components including
   1. data requirements, radiocommunication requirements relating to safety of life applications, performance criteria
   2. existing allocations to determine whether additional spectrum is required

This agenda item relates to taking necessary actions, as appropriate, to facilitate global or regional harmonized frequency bands to support railway radiocommunication systems between train and trackside within existing mobile service allocations, in accordance with Resolution 236 [COM6/12] (WRC-15).

The Resolution notes that Study Group 5 is studying relevant technical and operational characteristics for railway radiocommunication systems.

It also emphasizes that the provisions of Nos. 1.59 and 4.10 (relating to safety services) do not apply for railway radiocommunication systems.

The ITU-R is invited to study the spectrum needs, technical and operational characteristics and implementation of railway radiocommunication systems between train and trackside.

This agenda item relates to consideration of possible global or regional harmonized frequency bands, to the maximum extent possible, for the implementation of evolving Intelligent Transport Systems (ITS) under existing mobile-service allocations, in accordance with Resolution 237 [COM6/13] (WRC-15).

ITS systems are communication applications for the purpose of improving traffic management and assisting safe driving and the Resolution notes use of bands around 5.8 GHz for short range applications.

It also emphasizes that the provisions of Nos. 1.59 and 4.10 (relating to safety services) do not apply for railway radiocommunication systems.

The ITU-R is invited to carry out studies on technical and operational aspects of evolving ITS implementation using existing mobile-service allocations.

This agenda item relates to consideration of 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 [COM6/20] (WRC-15). It calls for studies on frequency-related matters for IMT identification including possible additional allocations to the mobile services on a primary basis in portion(s) of the frequency range between 24.25 and 86 GHz.

The ITU-R is invited to study:

1. spectrum needs of IMT taking into account factors such as technical and operational parameters of IMT, deployment scenarios and time frames,
2. appropriate sharing and compatibility studies taking into account the protection of primary services, including adjacent bands where appropriate.

This agenda item relates to consideration, on the basis of ITU-R studies in accordance with Resolution 160 [COM6/21] (WRC-15), of appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed-service allocations.

The ITU-R is invited to study:

1. the additional spectrum needs for gateway and fixed terminal links for HAPS taking into account the existing identifications and deployments of HAPS, deployment scenarios for HAPS, technical and operational characteristics of HAPS,
2. the suitability of using existing identifications,
3. appropriate modifications to existing regulations in order to facilitate HAPS use in currently identified frequency bands,
4. frequency bands 38 - 39.5 GHz globally and in Region 2 21.4 - 22 GHz and 24.25 - 27.5 GHz, already allocated to the FS on a primary basis not subject to Appendices 30, 30A and 30B, to meet any spectrum needs not met by 1. and 2.

These studies shall include sharing and compatibility studies to ensure protection of existing services in the bands identified and if necessary adjacent bands.

This agenda item relates to consideration of identification of frequency bands for use by administrations for the land-mobile and fixed services applications operating in the frequency range 275-450 GHz, in accordance with Resolution 767 [COM6/14] (WRC-15).

The ITU-R is invited to:

This agenda item relates to consideration of issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between 5 150 MHz and 5 925 MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 [COM6/22] (WRC-15).

The ITU-R is invited to:

1. study WAS/RLAN technical characteristics and operational requirements,
2. conduct studies with a view to identify potential WA/RLAN mitigation techniques to facilitate sharing with incumbent services at 5 150 - 5 350 MHz, 5 350 - 5 470 MHz, 5 725 - 5 850 and 5 850 - 5925 MHz,
3. to perform sharing and compatibility studies in the band 5 150 - 5 350 MHz of the possibility of enabling outdoor WLAN/RLAN operations
4. to conduct further sharing and compatibility studies between WA/RLAN applications and incumbent services at 5 350 - 5 470 MHz addressing:
   1. whether additional mitigation techniques would provide coexistence with EESS (active) and SRS (active) systems,
   2. with radio determination systems and,
   3. hence whether an allocation could be made to the mobile service for use by WAS/RLANs,
5. to conduct detailed sharing and compatibility studies including mitigation techniques between WAS/RLAN and incumbent services in the band 5 725 - 5 850 MHz with a view of enabling a mobile service to accommodate WAS/RLAN use, and
6. to conduct detailed sharing and compatibility studies including mitigation techniques between WAS/RLAN and incumbent services in the band 5 850 - 5 925 MHz with a view to accommodating WAS/RLAN use under the existing mobile allocation while not imposing any additional constraints on the existing services.

This relates to the implementation of IMT in the frequency bands 1 885-2 025 MHz and 2 110-2 200 MHz.

The Resolution invites the ITU-R to study possible technical and operational measures to ensure coexistence and compatibility between terrestrial and satellite components of IMT, in particular in the frequency bands 1 980 - 2 010 MHz and 2 170 - 2 220 MHz.

This agenda item relates to compatibility of IMT and BSS (sound) in the frequency band 1 452-1 492 MHz in Regions 1 and 3.

The Resolution invites the ITU-R to:

1. undertake appropriate regulatory and technical studies of compatibility between these two services, in particular between IMT and BSS earth stations
2. prepare regulatory actioin that could be taken based upon these studies that coudl facilitate the long-term stability of IMT and BSS(sound) in this band

This could then be used, where appropriate, to determine the need for bilateral coordination.

This agenda item relates to studies relating to spectrum needs and possible allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (Earth-to-space).

The Resolution invites the ITU-R to:

1. study the additional spectrum needs for development of the FSS taking into account bands currently allocated to that service, the conditions of their use and the possible optimization of these frequencies to increase spectrum efficiency,
2. sharing and compatibility studies with existing services on a primary and secondary basis including as appropriate adjacent bands to determine the suitability of new primary allocations for FSS at 51.4 - 52.4 GHz (E-s) limited to FSS feeder links for GSO use and associated regulations,
3. studies towards possible revision of Resolution 750 (Rev. WRC-12) so that systems in the passive band 52.6 - 54.25 GHz are protected and
4. studies regarding the protection of the radio astronomy service and including any appropriate regulatory measures.
