Agenda Item Description
Agenda Item 1.4

This agenda item considers use of high altitude platform stations as IMT base stations (HIBS) in the mobile service in some bands below 2.7 GHz. In particular, the bands:

  1. 694 - 960 MHz
  2. 1 710 - 1 885 MHz (1 710 - 1 815 MHz for uplink only in Region 3)
  3. 2 500 - 2 690 MHz (2 500 - 2 535 MHz for uplink only in Region 3 except 2 655 - 2 690 MHz in Region 3)

The ITU-R is invited to study:

  1. spectrum needs for HIBS
  2. sharing and compatibility studies (including with services in adjacent bands where appropriate) in order to protect services with an existing primary allocation without imposing any additional technical or regulatory constraints in their deployment
  3. modifications to existing footnote and resolutions in order to facilitate use of HIBS with the latest radio interface technologies of IMT
  4. the definition of HIBS and possible modification to the RR as appropriate
Agenda Item 1.5

This agenda item is to review the spectrum use and needs of existing services in the frequency band 470 - 960 MHz in Region 1 and consider possible regulatory actions in the frequency band 470 - 694 MHz in Region 1 on the basis of the review in accordance with Resolution 235

The ITU-R is invited to:

  1. review the spectrum use and study the spectrum needs of existing services within the frequency band 470 - 960 MHz in Region 1, in particular the spectrum needs for broadcasting and mobile (excluding aeronautical)
  2. carry out sharing and compatibility studies, as appropriate, in the frequency band 470 - 694 MHz between broadcasting and mobile (excluding aeronautical)
  3. sharing and compatibility studies in order to provide relevant protection of systems of other existing services
Agenda Item 1.9

This agenda item is to review Appendix 27 of the Radio Regulations and consider appropriate regulatory actions and updates based on ITU-R studies in order to accommodate digital technologies for commercial aviation safety-of-life applications in existing HF bands allocated to the aeronautical mobile (route) service and ensure coexistence of current HF systems alongside modernized HF systems

The ITU-R is invited to study:

  1. any necessary modifications to Appendix 27 for the aeronautical mobile (route) service between 2 850 and 22 000 kHz
  2. to identify any necessary transition arrangements
  3. to recommend how new digital aeronautical wideband HF systems can be introduced while ensuring compliance with safety requirements
  4. to define the relevant technical characteristics and to conduct any necessary sharing and compatibility studies with incumbent services that are allocated on a primary basis in the same or adjacent frequency bands to avoid harmful interference
Agenda Item 1.12

This agenda item is to study a possible new secondary allocation to the EESS (active) service for spaceborne radar sounders within the range of frequencies around 45 MHz, taking into account the protection of incumbent services, including in adjacent bands.

WRC-23 is invited to consider the results of studies on spectrum needs for a possible new secondary allocation to the EESS(Active) service for spaceborne radar sounders within the range of frequencies around 45 MHz taking into account the protection of incumbent services

The ITU-R is invited to conduct studies on spectrum needs and sharing studies between the EESS(Active) service and the radiolocation, fixed, mobile, broadcasting, amateur and space research services in the 40 - 50 MHz frequency range and in adjacent bands

Agenda Item 9.1.1

This agenda item is to review the results of studies relating to the technical and operational characteristics, spectrum requirements and appropriate radio service designations for space weather sensors with a view to describing appropriate recognition and protection in the Radio Regulations without placing additional constraints on existing services.

The ITU-R is invited to:

  1. to identify, in time for WRC-23, and based upon existing and possible further ITU-R studies on the technical and operational characteristics, specific space weather sensors which need to be protected by appropriate regulation. This includes determining if receive-only space weather sensors shall be designated as applications of the Metaids services, to determine the appropriate radiocommunication service, if any, for cases where it is determined that receive-only space weather sensors do not fall under the Metaids service
  2. to conduct, in time for WRC-23, any necessary sharing studies with incumbent systems operating in frequency bands used by space weather sensors with the objective of determine potential regulatory provisions that can be provided to receive-only operational space weather sensors for their appropriate recognition in the Radio Regulations, while not placing additional constraints on incumbent services
  3. to develop potential solutions to describe in the Radio Regulations in Articles 1 and 4 and/or as a WRC resolution, if deemed appropriate, for consideration by WRC-23, space weather sensor systems and their corresponding usage, as well as protection requirements for receive-only space weather sensors
  4. to conduct studies, in time for WRC-23, on the technical and operational characteristics of active space weather sensors and conduct necessary sharing studies with incumbent systems operating in frequency bands used by active space weather sensors, with the objective of determining the appropriate radiocommunication service for those sensors

The Director of the BR is instructed to report on the results of the ITU-R studies to WRC-23

Agenda Item 9.1.3

This agenda item is to study the use of International Mobile Telecommunication (IMT) system for fixed wireless broadband in the frequency bands allocated to the fixed services on primary basis.

The ITU-R is invited to conduct any necessary studies on the use of IMT systems for fixed wireless broadband in the frequency bands allocated to the fixed service on primary basis, taking into account the relevant ITU-R studies, Handbooks, Recommendations and Reports

The Director of the BR is instructed to report on the results of the ITU-R studies to WRC-23
