Agenda Item Description
Agenda Item 1.2

This agenda item considers identification of frequency bands 3 300 - 3 400 MHz (Region 2 and amend footnote in Region 1), 3 600 - 3 800 MHz (Region 2), 6 425 - 7 025 MHz (Region 1), 7 025 - 7 125 MHz (globally) and 10.0 - 10.5 GHz (Region 2) for IMT including possible allocations to the mobile service on a primary basis.

The ITU-R is invited to study:

  1. technical, operational and regulatory issues pertaining to possible use of the terrestrial component of IMT in the bands listed taking into account evolving needs, technical and operational characteristics of terrestrial IMT systems, evolution of IMT, deployment scenarios, needs of developing countries and time-frame in which spectrum would be needed
  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 additional regulatory or technical constraints, and also, as appropriate, on services in adjacent bands
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 1.10

This agenda item is to conduct studies on spectrum needs, coexistence with radiocommunication services and regulatory measures for possible new allocations for the aeronautical mobile service for the user of non-safety aeronautical mobile applications.

The ITU-R is invited to study:

  1. spectrum needs for new non-safety aeronautical mobile applications for air-to-air, ground-to-air and air-to-ground communications of aircraft systems.
  2. sharing and compatibility studies in the frequency band 22 - 22.21 GHz, already allocated on a primary basis to the mobile except aeronautical mobile service, in order to evaluate the possible revision or deletion of the "except aeronautical mobile" restriction while ensuring the protection of primary services in the considered frequency bands and, as appropriate, in adjacent frequency bands.
  3. sharing and compatibility studies on possible new primary allocations to the aeronautical mobile service for non-safety aeronautical applications in the frequency band 15.4 - 15.7 GHz while ensuring the protection of primary services in the considered frequency bands and, as appropriate, adjacent bands
  4. definition of appropriate protection for passive services and radio astronomy allocated in adjacent bands from unwanted emission of AMS
Agenda Item 1.13

This agenda item is to consider a possible upgrade of the allocation of the frequency band 14.8 - 15.35 GHz to the space research service. The ITU-R is invited to:

  1. to investigate and identify all relevant scenarios that need to be considered in compatibility and sharing studies, taking into account the latest relevant ITU-R Recommendations
  2. to conduct and complete in time for WRC-23 sharing and compatibility studies in order to determine the feasibility of upgrading the SRS allocation to primary status in the frequency band 14.8 - 15.35 GHz with a view to ensuring protection of the primary service
  3. to determine the technical and regulatory conditions according to the results of studies

WRC-23 is invited to examine, on the basis of the results of studies by the ITU-R, the possibility of upgrading the secondary status of the allocation of the SRS to primary status in the frequency band 14.8 - 15.35 GHz taking into account studies

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
