ITU-R M.2150-1 (5G RAN standard) will include 3GPP Release 17 enhancements; future revisions by 2025
ITU-R Recommendation M.2150 (previously known as IMT 2020) is being updated with new features for the 3GPP and ETSI-DECT 5G radio interface specifications in Annex 1, 2 and 4. This updated recommendation has been given the temporary name “M.2150-1.”
The main changes include the addition of enhanced capabilities for 3GPP 5G-SRIT (Set of Radio Interface Technologies), 3GPP 5G-RIT (Radio Interface Technology), DECT 5G-SRIT, and some consequential changes to the overview sections of the text, as well as to the Global Core Specifications.
This M.2150-1 revision is expected to be completed at ITU-R WP 5D meeting #44 which is June 13-22, 2023 in Geneva.
Annex 1: 3GPP 5G SRIT
The main purpose of this update is to align Rec. ITU-R M.2150 to the Release 17 December 2022 version of the 3GPP Specifications of 3GPP 5G-SRIT. The main features introduced in this update are:
– Addition of new modulation schemes for NB-IoT and LTE-M (LPWANs for IoT connectivity)
– The addition of new numerologies for NR;
– New logical channels and their mapping to physical channels;
– Reduced Capability (RedCap) NR devices.
Annex 2: 3GPP 5G RIT- aka “5G-NR”
The main purpose of this update is to align Rec. ITU-R M.2150 to the Release 17 December 2022 version of the 3GPP Specifications of 3GPP 5G-RIT. The main features introduced in this update are:
– The addition of new numerologies for NR
– New logical channels and their mapping to physical channels
– Reduced Capability (RedCap) NR devices.
IMPORTANT NOTE: Since 3GPP Release 16 5G-NR URRLC in the RAN spec has not been completed yet, it was not submitted to 5D for inclusion in M.2150-1. Therefore, ITU M.2150-1 still does not meet the URLLC Minimum Performance Requirements specified in ITU-R M.2410. In particular, 3GPP Rel 16 URRLC in the RAN:
| 1335 | 830074 | Physical Layer Enhancements for NR Ultra-Reliable and Low Latency Communication (URLLC) | NR_L1enh_URLLC | 1 | Rel-16 | R1 | 6/15/2018 | 12/22/2022 | 96% | RP-191584 |
Annex 4: DECT 5G – SRIT
The DECT 5G – SRIT consists of two components: 1.] DECT-2020 NR and 2.] 3GPP 5G-NR. The followings contain the information for each of the component RITs.
– DECT-2020 NR component RIT The original submission contained the layers up to the ‘Medium Access Control’ layer. In this update the ‘Data Link Control’ (DLC) and ‘Convergence’ (CVG) layers have been added.
– 3GPP 5G- NR component RIT. The changes are identical to those in Annex 2. The main purpose of this update is to align Rec. ITU-R M.2150 to the Release 17 December 2022 version of the 3GPP Specifications of 3GPP 5G-RIT.
• The addition of new numerologies for NR
• New logical channels and their mapping to physical channels
• Reduced Capability (RedCap) NR devices.

ITU-R WP5D meeting #43 considered future revisions of Recommendations ITU-R M.2150 (and ITU-R M.2012) after year 2023 and prepared initial and preliminary revision schedules in which revisions of both Recommendations would be completed by the end of 2025. That may or may not include what pundits label “5G-Advanced,” which is coming from 3GPP Release 18.
………………………………………………………………………………………………………………………………………..
Objectives for WP5D – WG Technology Aspects at the 44th WP 5D meeting (June 12-23, 2023 in Geneva):
i) finalize preliminary draft revision “after year 2021” of Recommendation ITU-R M.2150;
ii) finalize preliminary draft revision of Recommendation ITU-R M.2012-5;
iii) finalize the Report ITU-R M.[IMT.ABOVE 100GHz];
iv) finalize preliminary draft revisions of Recommendations ITU-R M.2070-1 and ITU‑R M.2071-1 “Generic unwanted emission IMT‑Advanced”;
v) continue working on OOBE BS/MS for IMT-2020 “Generic unwanted emissions IMT‑2020.”

Generic unwanted emission characteristics of IMT-2020 mobile/base stations:
Working document of Recommendation ITU-R M.[IMT-2020.UNWANT.BS] was updated after discussion of the one contribution to this meeting; however further discussion is needed at next meeting.
As has been the case for the past two years, ITU-R WP5D Sub-Working Group Frequency Arrangements reviewed the input contributions at its Feb 2023 meeting and had extensive online and offline email discussions to improve the document. SWG Frequency Arrangements was not able to achieve consensus to complete the revision of Recommendation ITU-R M.1036-6 at the meeting.
Hence, there continues to be no standard/recommendation on what frequencies and frequency arrangements are to be used for 5G RAN, especially mmWave!
Note that 3GPP Release 17 work on 5G NR over Non Terrestrial Networks (NTN) was NOT submitted by ATIS to ITU-R WP5D for inclusion in ITU-R M.2150-1. It must be submitted and accepted at the next (44th) WP 5D meeting, June 12-23, 2023 in Geneva to be included in the published ITU-R M.2150-1 recommendation.
Does any1 realize that the failure of 3GPP to complete URLLC in the RAN (Release 16) has been a key reason there are no 5G killer apps? That is because neither mission critical apps requiring ultra high reliability AND real time control apps requiring ultra low latency (e.g. <=1 ms in data plane) could not exist as there was no spec to meet ITU-R M.2410 performance reqts for URLLC use case!
It’s important to note that ITU-R M.2150-1 only included 5G NR enhancements in 3GPP Release 17. 3GPP Release 18 is expected to be finalized in mid-2024 with Release 19 following in late 2025. Only after final approval, i.e. “frozen” state, will 3GPP send it’s specifications to ITU-R WP5D (via ATIS) for approval and add on to ITU-R M.2150-2.
The scope of 5G Advanced Release 19 was approved at the 3GPP’s Plenary Meeting in Edinburgh in December, 2023. Release 19 builds on Release 18 and focuses on enhancing 5G performance while expanding the capability of 5G across devices and deployments. In addition, it will establish the technical foundations for 6G and will include preliminary work on new 6G capabilities. Release 19 will be followed by Release 20, the first 3GPP release for 6G studies.
During the next few years, 5G Advanced will continue to evolve within 3GPP while the standardization of 6G officially starts to ramp up in parallel.
