At its March 2021 virtual meeting, ITU-R WP5D completed a revision of the report ITU-R M.2291-1 – The use of International Mobile Telecommunications (IMT) for broadband Public Protection and Disaster Relief (PPDR) applications includes the IMT-2020 and 5G aspects in this public safety focused report to update the current report which was only based on IMT-Advanced 3GPP LTE technology. This revision was completed by ITU-R WP 5D and forwarded to Study Group 5 for action when they next meet in November 2021.

ITU-R M.[IMT.C-V2X] – The use of the terrestrial component of IMT systems for Cellular-Vehicle-to-Everything

WP 5D is also developing a draft new report ITU-R M.[IMT.C-V2X] – The use of the terrestrial component of IMT systems for Cellular-Vehicle-to-Everything is intended to addresses the mutual relationship between IMT technologies and Cellular-Vehicle-to-Everything (C-V2X) as a specific application and elements of functions in IMT technologies that are used to realize C-V2X application.

Further, the report provides details on Overview on Usage of IMT technology, use cases, relationship between IMT and C-V2X, characteristics and capabilities supported by IMT, and case studies associated with C-V2X for the various scenarios including eMBB, mMTC, and URLLC of terrestrial component of IMT.

Development of draft new report ITU-R M.[IMT.FUTURE TECHNOLOGY TRENDS TOWARDS 2030 AND BEYOND]

The draft new Report ITU-R M.[IMT.FUTURE TECHNOLOGY TRENDS TOWARDS 2030 AND BEYOND] is intended as a precursor to a “beyond IMT-2020” vision document for 6G that ITU-R WP 5D intends to produce in 2022. This trends report will assess where the technology is, and the current uses are for IMT-2020/5G and seek to identify the gaps and technical enablers anticipated to be necessary in the 2030 timeframe.

Furthermore, the expectation is that this Report will energize the academic and technology community to engage in the research and developments necessary to underpin a “beyond IMT-2020 and 6G view) as just focusing on new uses cases is insufficient to build such a future and the technology evolution requires a long lead time to fruition.

Development of draft new report ITU-R M.[IMT TERRESTRIAL BROADBAND REMOTE COVERAGE]

The draft new Report ITU-R M.[IMT TERRESTRIAL BROADBAND REMOTE COVERAGE] – Terrestrial IMT for remote sparsely populated areas providing high data rate coverage is intended to provide details on scenarios associated with the provisioning of enhanced mobile broadband services to remote sparsely populated and underserved areas with a discussion on enhancements of user and network equipment.

It will distinguish between extending coverage on already deployed network and defining a use/case for deployment environment and is meant to meant to evaluate technical solutions required to extend the coverage of IMT system rather than discussing deployment layout for rural environments. The completion dates have been extended to the 39^th WP 5D meeting (October 2021).

Development of a draft new report ITU-R M.[IMT 2020.TDD.SYNCHRONIZATION]

The draft new report ITU-R [IMT2020.TDD.SYNCHRONIZATION] is intended to address the study of the aspects of synchronization operations of multiple IMT-2020 TDD networks in close proximity using the same frequency band, including analyses of coexistence issues when IMT operators utilize different synchronization modes, performance evaluation under different synchronization modes, and coexistence mitigation strategies.

The Report considers the further impacts of the introduction of technical advancement such as active antenna systems, etc. The completion dates were extended to the 41^st WP 5D meeting (June 2022).
