|Agenda Item 1.13
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:
- spectrum needs of IMT taking into account factors such as technical and operational parameters of IMT, deployment scenarios and time frames,
- appropriate sharing and compatibility studies taking into account the protection of primary services, including adjacent bands where appropriate.
|Agenda Item 1.15
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:
- identify the technical and operational characteristics of systems in the land-mobile and fixed services operating above 275 GHz,
- to study these system's spectrum needs,
- to develop propagation models appropriate for this frequency range to support compatibility analysis between land-mobile, fixed and passive services,
- to conduct sharing studies between these services while maintaining protection of the passive services in 5.565, and
- to identify candidate frequency bands for the land-mobile and fixed services taking into account the results of 1-4 above.
|Agenda Item 1.16
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:
- study WAS/RLAN technical characteristics and operational requirements,
- 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,
- to perform sharing and compatibility studies in the band 5 150 - 5 350 MHz of the possibility of enabling outdoor WLAN/RLAN operations
- to conduct further sharing and compatibility studies between WA/RLAN applications and incumbent services at 5 350 - 5 470 MHz addressing:
- whether additional mitigation techniques would provide coexistence with EESS (active) and SRS (active) systems,
- with radio determination systems and,
- hence whether an allocation could be made to the mobile service for use by WAS/RLANs,
- 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
- 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.
