WRC 2019 Agenda Item Details

Agenda Item: Agenda Item 1.13
Resolution(s): Resolution 238 [COM6/20] (WRC-15)
Description of work:

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:

  1. spectrum needs of IMT taking into account factors such as technical and operational parameters of IMT, deployment scenarios and time frames,
  2. appropriate sharing and compatibility studies taking into account the protection of primary services, including adjacent bands where appropriate.
Comments: This AI could be a considered a follow-on to AI 1.1 in the previous cycle which considered identification of frequency bands for IMT at frequencies up to 6 GHz. This AI was sometimes described during discussions prior to WRC-15 as an AI for IMT above 6 GHz but in discussions at WRC-15 there majority of the proposals were to study above about 20 GHz.
Lead Working Party(s): TG 5/1
Involved Working Parties: WP 3J, WP 3K, WP 3M, WP 4A, WP 4B, WP 4C, WP 5A, WP 5B, WP 5C, WP 5D, WP 6A, WP 7B, WP 7C, WP 7D
How Visualyse products can help: Visualyse Professional can model the wide range of scenarios that covered by this AI. It is able to model IMT systems including both base and mobile transmit, beam forming antennas, sectorial antennas, Monte Carlo locations and traffic models. It is also able to model a wide range of other systems including fixed (point to point, point to multi-point and multi-point to multi-point), satellite services including FSS, EESS and SRS, and other services such as short range radar, etc. Propagation models that could be used include P.452 and P.2001, which takes account of terrain and/or clutter databases, or generic models such as dual slope / triple slope models. Analysis can be undertaken using a number of methodologies including static, dynamic, area or Monte Carlo or combinations of these and could be either co-frequency or non-co-frequency using mask integration. Visualyse Professional was widely used for studies in the previous ITU-R group JTG 4-5-6-7.
How Transfinite consultants can help: We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at the ITU-R WPs. Using our in house Visualyse Professional we can quickly model a very wide range of systems, services and scenarios. We have particularly good experience in these sorts of studies as our consultants were active in the JTG 4-5-6-7 which studied various aspects of IMT under AI 1.1 in the last study cycle at national, regional and international level.
