Agenda Item Description
Agenda Item 1.7

This agenda item is to consider studies on sharing and compatibility and develop technical conditions for use of IMT in the frequency bands 4.4 - 4.8 GHz, 7.125 - 8.4 GHz (or parts of) and 14.8 - 15.35 GHz taking into account existing primary services operating in those bands or adjacent frequency bands.

The ITU-R is invited to study:

1. the technical, operational and regulatory issues pertaining to the possible use of the terrestrial component of IMT in these bands taking into account:

  • the evolving needs to meet emerging demand for IMT
  • technical and operational characteristics of terrestrial IMT that would operate in these bands including the evolution of IMT through advances in technology and spectrally efficient techniques
  • deployment scenarios envisaged for IMT systems and related requirements of balanced coverage and capacity
  • the needs of developing countries
  • the time-frame in which spectrum would be needed

2. sharing and compatibility studies with a view to ensuring the protection of services for which the band is allocated on primary basis including protection of stations operating in international waters or airspace which cannot be registered in the MIFR without imposing additional regulatory or technical constraints on these services and also on services in adjacent bands

WRC-27 is invited to consider the results of the above studies and take necessary actions, as appropriate.
Agenda Item 1.8

This agenda item is to consider possible additional allocations to the radiolocation service (RLS) on a primary basis in the frequency range 231-275 GHz and possible new identifications for the radiolocation service applications in frequency bands in the frequency range 275 - 700 GHz for millimetric and sub-millimetric wave imaging systems.

The ITU-R is invited to study:

  1. technical and operational characteristics including protection criteria for receive-only and active millimetric and sub-millimetric wave RLS
  2. studies on globally harmonized spectrum for RLS
  3. sharing and compatibility studies (in-band and adjacent) for RLS and other services in the frequency range 231.5 - 275 GHz while ensuring protection for the current use and further development of the incumbent services allocated to this frequency range
  4. sharing and compatibility studies (in-band and adjacent band) for RLS applications with EESS(passive), space research service (passive) and RAS applications in the frequency range 275-700 GHz while maintaining protection for the passive service applications identified in No. 5.565
  5. sharing and compatibility studies (in-band and adjacent bands) for RLS applications with fixed service and land mobile service applications in the frequency range 275 - 450 GHz as identified in No. 5.564A

WRC-27 is invited to consider the results of the above studies and take necessary actions, as appropriate.
