5G from 3GPP: Release 17

Further 5G system enhancements are set to follow in Release 17, scheduled for delivery in 2021. R17 defines “Strong Radio Evolution”.

3GPP Release 17 Summary

3GPP 5G Release 17 R17

5G Release 17 Technology:

For Release-17 work in RAN1, RAN2, and RAN3: defines physical layer, radio protocol and radio architecture enhancements. The physical layer work in RAN1 will start at the beginning of next year, whilst radio protocol and architecture work in RAN2 and RAN3, respectively, will start in the 2nd quarter.

Physical layer enhancements (RAN1)

RAN1 will start working on several features that continue to be important for overall efficiency and performance of 5G NR: MIMO, Spectrum Sharing enhancements, UE Power Saving and Coverage Enhancements. RAN1 will also undertake the necessary study and specification work to enhance the physical layer to support frequency bands beyond 52.6GHz, all the way up until 71 GHz. The summary figure below shows the Release-17 content for RAN1 with the planned RAN1 time allocations (TU) in each quarter.


Radio protocol enhancements (RAN2)

In RAN2, the work starts in the second quarter of 2020. The necessary protocol enhancements for the newly added physical layer driven features will be added. The summary figure below shows the Release-17 content for RAN2 with the planned RAN2 time allocations (TU) in each quarter – note that these allocations may be revised at RAN#87 in March.


Radio architecture enhancements (RAN3)

In RAN3, Release 17 will also start in the 2nd quarter of 2020. Architecture support will be added to all necessary RAN1- and RAN2-led features. The summary figure below shows the Release-17 content for RAN3 with the planned RAN3 time allocations (TU) in each quarter.

3GPP R17 RAN3 Release 17

RAN3 will also address the QoE needs of 5G NR, initially starting with a study to understand how different the QoE function would need to be compared to what was specified for LTE.

The radio architecture of 5G NR is substantially more versatile than LTE through the split of gNB: Control- and Userplane split, as well as the split of Centralized Unit and Distributed Unit. RAN3 will now add support for CP-UP split to LTE to so that LTE networks can also take advantage of some of the advanced radio architecture functions of 5G.

3GPP R17 Summary

Release 17 is perhaps the most versatile release in 3GPP history in terms of content. Still, the scope of each feature was carefully crafted so that the planned timelines can be met despite the large number of new features. As RAN Chairman I have the utmost confidence that the Working Groups will be able to deliver the specifications for all the planned functionality within the designated timeline.

5G Release 17 standards work

5G Release 17 is considered “Work in Progress” for definition.

July 3, 2020 Update:
Discussions at TSG#88-e Plenaries identified that the Rel-17 dates are at risk of being delayed. This is due to switch from physical meetings to e-meetings. In SP-200606, the Work Plan manager noted that both SA2 for Stage 2 work (SP-200536) and TSG RAN (RP-201257) had warned that Rel-17 dates will have to be shifted. This will be further discussed in Sept 2020, during TSG#89-e.

At TSG#87e (March, 2020) the following Rel-17 timeline was agreed:

Rel-17 Stage 3 freeze September 2021
Rel-17 ASN.1 and OpenAPI specification freeze: December 2021

3GPP 5G Release 17

December 2019 Update:
At the December Plenaries, TSG RAN#86 meeting had outlined its ambitious schedule in the ‘Release 17 package for RAN’ presentation, which contains slides on the time to be spent (Time Units) on RAN features for Rel-17. In the light of the latest decision – In March – Here are the 3GPP RAN milestones as a consequence of the cancellation of WG and TSG face-to-face meetings.

5G from 3GPP: Release 16

5G technology received updates with “Release 16” (R16) from the 3GPP
At the TSG#88e Plenary meeting on July 3, 2020 – Release 16 was completed with both the Stage 3 freeze and the ASN.1 and OpenAPI specification freeze being approved.

3GPP Release 16 Summary

5G 3GPP Release 16 R16 5G-SA Satellite Access Integrated Access and Backhaul

5G Release 16

Release 16 is a major release for the project, not least because it brings the IMT-2020 submission for an initial full 3GPP 5G system to completion .

Work has progressed on around 25 Release 16 studies, on a variety of topics: Multimedia Priority Service, Vehicle-to-everything (V2X) application layer services, 5G satellite access, Local Area Network support in 5G, wireless and wireline convergence for 5G, terminal positioning and location, communications in vertical domains and network automation and novel radio techniques. Further items being studied include security, codecs and streaming services, Local Area Network interworking, network slicing and the IoT.

Technical Reports (the result of the study phase) have also been developed on broadening the applicability of 3GPP technology to non-terrestrial radio access (initially satellites, but airborne base stations are also to be considered) and to maritime aspects (intra-ship, ship-to-shore and ship-to-ship). Work also progresses on new PMR functionality for LTE, enhancing the railway-oriented services originally developed using GSM radio technology that is now nearing end of life.

Part of R16, MC services are extended to address a wider business sector than the initial rather narrow public security and civil defence services for which they had originally been developed. If the same or similar standards can be used for commercial applications (from taxi dispatching to railway traffic management, and other vertical sector scenarios currently being investigated), this would bring enhanced reliability to those MC services through wider deployment, and reduced deployment costs due to economies of scale to the benefit of all users.
