As defined in Resolution ITU-R 56-3, International Mobile Telecommunications-2030 (IMT-2030) systems are mobile systems that include new radio interface(s) which support enhanced capabilities and new capabilities beyond IMT‑2020, IMT-Advanced and IMT-2000. In Recommendation ITU-R M.2160 ‒ Framework and overall objectives of the future development of IMT for 2030 and beyond, the capabilities of IMT-2030 are identified, which aims to make IMT-2030 more capable, flexible, reliable and secure than previous IMT systems when providing diverse and novel services in the intended six usage scenarios (see figure below), including immersive communication, hyper reliable and low‑latency communication (HRLLC), massive communication, ubiquitous connectivity, artificial intelligence and communication, and integrated sensing and communication (ISAC).
IMT-2030 is expected to support enriched and potential immersive experience, enhanced ubiquitous coverage, and enable new forms of collaboration. Furthermore, IMT-2030 is envisaged to support expanded and new usage scenarios compared to those of IMT-2020, while providing enhanced and new capabilities. In accordance with the IMT-2030 (6G) timeline within ITU-R, development of IMT-2030 Technical Performance Requirements (TPR) is expected to start in ITU-R Working Party 5D (WP 5D) at the February 2024 meeting in Geneva.
- The IMT-2030 performance requirements are to be evaluated according to the criteria defined in Report ITU-R M.[IMT‑2030.EVAL] and Report ITU-R M.[IMT-2030.SUBMISSION] for the development of IMT-2030.
- Recommendation ITU-R M.2160 defines fifteen key “Capabilities of IMT-2030,” which form a basis for the [x] technical performance requirements to be specified in the forthcoming draft document.
In order to facilitate the work of this important phase of IMT-2030 development, Apple, China, and India separately proposed outlines or suggestions for a working document towards a preliminary draft new report on technical performance requirements of IMT-2030. Those contributions will be presented and discussed at the February 2024 ITU-R WP 5D meeting in Geneva, Switzerland.
The proposed technical performance parameters include:
Peak data rate, Peak spectral efficiency, User experienced data rate, 5th percentile user spectral efficiency, Average spectral efficiency, Area traffic capacity, Latency, User plane latency, Control plane latency, Connection density, Energy efficiency, Reliability, Mobility, Mobility interruption time, Bandwidth, Coverage, Positioning, Sensing, AI, Security, Sustainability, and Interoperability.
This work will certainly refer to IMT-2030 set of expected capabilities are outlined in ITU-R M.2160 Framework and overall objectives of the future development of IMT for 2030 and beyond, which was approved in November 2023. A broad variety of capabilities associated with envisaged usage scenarios, are described in that recommendation.
Huge caveat: It’s important to note that the IMT 2020 (5G) Technical Performance Parameters specified in ITU-R M.2410 for URLLC use case have STILL NOT BEEN achieved. Furthermore, the 3GPP spec for URLLC in the RAN has not been performance tested or submitted to ITU-R WP5D, even though it was “frozen” June 2020 in 3GPP Rel 16. Hence, one must wonder if this proposed IMT 2030 Performance Parameter spec will be yet another “paper tiger?”
IMT 2020.SPECS approved by ITU-R but may not meet 5G performance requirements; no 5G frequencies (revision of M.1036); 5G non-radio aspects not included
