Building a prosperous and innovative Canada

2. Purpose
TG 5/1 is tasked with conducting the sharing and compatibility studies for WRC-19 agenda item 1.13, in accordance with Resolution 238 (WRC‑15), and with developing the draft CPM text for this agenda item. AI 1.13 is “to consider 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 (WRC‑15)”

3. Scope
CPM text for AI 1.13
Sharing and compatibility studies between IMT-2020 and other incumbent services in the following frequency bands:
 GHz,  GHz,  GHz,  GHz,  GHz, 50.4‑52.6 GHz, 66-76 GHz and 81-86 GHz, which have allocations to the mobile service on a primary basis; and
 GHz,  GHz and  GHz, which may require additional allocations to the mobile service on a primary basis

4. Inputs from other Working Parties
Input from other WPs to be provided to TG 5/1 by 31 March 2017, at the latest:
Working Party 5D is to conduct and complete studies as indicated in resolves to invite ITU-R 1 of Resolution 238 (WRC-15), with regards to spectrum needs for the terrestrial component of IMT-2020 in the frequency range between 24.25 GHz and 86 GHz, technical and operational characteristics including protection criteria, and deployment scenarios for the terrestrial component of IMT-2020;
Other Working Parties to provide the technical characteristics including protection criteria for existing services allocated in, or adjacent to, the eleven frequency bands to be studied;
Working Parties of Study Group 3 are to provide the relevant propagation models for sharing studies for the eleven frequency bands.

1.6 to consider the development of a regulatory framework for non-GSO FSS satellite systems that may operate in the frequency bands  GHz (space-to-Earth), 39.5‑42.5 GHz (space-to-Earth),  GHz (Earth-to-space) and  GHz (Earth-to-space), in accordance with Resolution 159 [COM6/18] (WRC‑15);
1.14 to consider, on the basis of ITU‑R studies in accordance with Resolution 160 [COM6/21] (WRC‑15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed-service allocations;
Issue 9.1.9:
Resolution 162 [COM6/24] (WRC‑15)
Studies relating to spectrum needs and possible allocation of the frequency band  GHz to the fixed-satellite service (Earth-to-space)

12. Challenges Meeting room availability –hosts for meetings # 3 and 6?
Tremendous number of potential studies to do - prioritization by membership?
Short timeframe to complete studies – 1 year
No consensus on some sharing parameters in contributing groups but need parameters to start studies – TG 5/1 to decide on values?
Short timeframe between availability of propagation models and first TG 5/1 meeting = short timeline for development of technical contributions
Overlap of frequency bands with other agenda items will require coordination
Potential impact of national /regional identification of frequency bands for 5G before studies complete and before WRC-19

13. Opportunities
Develop new sharing mechanisms to enable coexistence of multiple services/applications
Be innovative in achieving efficient use of spectrum
Demonstrate collaboration amongst different interests to accomplish TG 5/1 work
