WRC 2027 Agenda Item Details
Agenda Item: | Agenda Item 1.13 |
Resolution(s): | Resolution 253 (WRC-23) |
Description of work: | This agenda item is to consider studies of a possible new allocation to the MSS for direct connectivity between space stations and IMT user equipment to complement terrestrial IMT network coverage. The ITU-R is invited to:
WRC-27 is invited to consider the results of the above studies and take necessary actions, as appropriate. |
Comments: | Yet another MSS agenda item! In this case its related to direct to device (D2D) allocations, a hot topic for several of the non-GSO constellations, which are already testing possible implementations, though under 4.4. |
Lead Working Party(s): | WP 4C |
Involved Working Parties: | WP 3L, WP 3M, WP 4A, WP 4B, 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 both GSO and non-GSO MSS and also terrestrial mobile services including 5G using features such as the gain pattern in Recommendation ITU-R M.2101, TDD and FDD modelling, deployment models for BS and UE including both uniform and non-uniform deployment and power control algorithms based upon the alpha parameter. Propagation models are available for space to space, space to Earth and terrestrial paths and Visualyse Professional can model both co-frequency and non-co-frequency interference scenarios. |
How Transfinite consultants can help: | We can undertake studies including analysis of sharing between the different services covered by this agenda item MSS and terrestrial mobile including IMT/5G systems plus those in adjacent bands. We can help identify suitable system characteristics and sharing criteria, and provide contributions and representation at ITU-R Working Parties. Using our in house Visualyse Professional we can quickly model a very wide range of systems, services and scenarios. |
