ITU-R WP 5D is responsible for the overall radio system aspects of the terrestrial component of International Mobile Telecommunications (IMT) systems, comprising the current IMT-2000, IMT-Advanced and IMT-2020 as well as IMT for 2030 and beyond.  Note that 5D’s work is only for terrestrial radio access network interfaces. It does not include 5G or 6G Core network or satellite network access.

​ITU-R WP5D Technology Aspects Working Group (WG) consists of several Sub Working Groups (SWGs):

SWG IMT SPECIFICATIONS, SWG EVALUATION, SWG RADIO ASPECTS, SWG IMT UNWANTED EMISSIONS, SWG IMT COORDINATION

Key objectives of WG Technology Aspects at their June 24-July 3, 2025 meeting include:

1. Continue revising Recommendation ITU-R M.2150-2 (5G)  and Recommendation ITU‑R M.2012-6 (IMT Advanced aka 4G), including consideration of further revision based on contribution;
2. Continue working on revision of Document IMT-2030/2 “Process” – submission, evaluation process and consensus building process for IMT-2030;
3. Start to work on candidate technology submission template for IMT-2030 (6G);
4. Continue working on Report ITU-R M.[IMT-2030.TECH PERF REQ] – minimum requirements related to technical performance for IMT-2030 radio interface(s);
5. Continue working on Report ITU-R M.[IMT-2030.EVAL] – Guidelines for evaluation of radio interface technologies for IMT-2030;
6. Continue working on Report ITU-R M.[IMT-TROPO DUCT MITIGATION] – Mitigation of interference for IMT network under tropospheric ducting effect;
7. Continue working on the documents of unwanted emission characteristics of base/mobile stations using the terrestrial radio interfaces of IMT-2020.
