Hi,
We have submitted a new Internet draft describing rLEDBAT for Quic (RXQ). RXQ a set of mechanisms that enable the execution of a less-than-best-effort congestion control algorithm for QUIC at the receiver end. This draft explores adaptation strategies for integrating rLEDBAT with QUIC's framework, aiming to maintain compatibility with QUIC.

This work gives an overview of an open disaggregated network architecture based on an Open Radio Access Network (O-RAN), including the current work from standards bodies and industry bodies in this area. Based on this architecture, a framework for the automation of xApp development and deployment is proposed. This is then aligned with the key concepts described in ITU-T in terms of the evolution, experimentation, and adaptation of controllers. The various steps in such an aligned workflow, including design, validation, and deployment of xApps, are discussed, and use case examples are provided to illustrate further our position regarding the mechanisms needed to achieve automation.

The initial draft output from the Focus Group on Autonomous Networks (website) can be found here.
The under discussion draft recommendation can be found here.
ITU-T Focus Group on Autonomous Networks was established by ITU-T Study Group 13 at its virtual meeting, 17 December 2020. The Focus Group will draft technical reports and specifications for autonomous networks, including exploratory evolution in future networks, real-time responsive experimentation, dynamic adaptation to future environments, technologies, and use cases. The Focus Group will also identify relevant gaps in the standardization of autonomous networks.
The primary objective of the Focus Group is to provide an open platform to perform pre-standards activities related to autonomous networks and leverage the technologies of others where appropriate.

A new Internet draft is available at the CONGRESS WG at the IETF discussing the idea of Congestion Control Invariants, that is mechanisms that several CCAs implement and that would benefit from a common specification for all CCAs to improve their interoperability.

- RFC 9331: The Explicit Congestion Notification (ECN) Protocol for Low Latency, Low Loss, and Scalable Throughput (L4S) https://www.rfc-editor.org/info/rfc9331
- RFC 9332: Dual-Queue Coupled Active Queue Management (AQM) for Low Latency, Low Loss, and Scalable Throughput (L4S) https://www.rfc-editor.org/info/rfc9332

The aim of this document is to study a set of necessary features/adaptations enabling the operation of the IoT NTN for 3GPP Release 17 with a priority on satellite access.
The Non-Terrestrial Network (NTN) New Radio (NR) and IoT (Internet of Things) work items in Rel-17 introduce new 5G network topologies into the 3GPP specifications. These topologies are designed based on high-altitude platforms, Low Earth Orbit (LEO), Medium Earth Orbit (MEO) and Geostationary Earth Orbit (GEO). The Rel-17 NTN NR and IoT work items are frozen in June 2022. The 3GPP Rel-17 specification covers eMTC and NB-IoT-based satellite access to address massive IoT use cases in transport, agriculture, and logistics areas.

The work in ETSI on Development of a "Framework for Implementing Autonomic/Autonomous IPv6 based 5G Networks, leveraging the ETSI GANA Multi-Layer AI / Multi-Layer Autonomic Management and Control Model and IPv6 Capabilities & Extensions that enable to Build Autonomic Networks", is progressing very well, and those who may want to join the work and contribute Use Cases on Autonomic Management anf Control Operations in an IPv6 based E2E 5G Networks are wellcome to contribute (Work Item is https://portal.etsi.org/webapp/WorkProgram/Report_WorkItem.asp?WKI_ID=63527). Examples of Use Cases for Autonomics (Closed Control-Loop operations by specific GANA Decision Elements(DEs) defined in ETSI TS 103 195-2, e.g. Mobility-Management-DE, Routing Management-DE, Forwarding Management-DE, Fault-Management-DE, etc) include the following Use Cases:
ITU-T SG13 "Future networks and emerging network technologies" has successfully started the new study period 2022-24 with the information that since the last SG13 meeting the following Recommendations in the field of 5G have been successfully approved and are now published.

ETSI ISG NIN (Non-IP Networking) was formed to support 21st century use cases -- including IoT and URLLC which are not well served by the TCP/IP suite -- by standardizing a platform that is not reliant on it, though IP is one of the protocols the platform supports.

The IETF has a non-working group email list in order to discuss about challenges in 6G Systems
List address: 6gip@ietf.org
Archive: https://mailarchive.ietf.org/arch/browse/6gip/
To subscribe: https://www.ietf.org/mailman/listinfo/6gip
Purpose: "6gip will discuss the spectrum of challenges of a new/visionary 6G system and will be scoped to work on selected issues regarding protocol design and architecture blueprint, considering service driven demands and the principle of overall context awareness as much as possible."
An important part of the remit of Global5G.org is to “… ensure broad outreach to vertical stakeholders and help build consensus on priority actions through ‘5G vertical market’ events to facilitate understanding on use case requirements and foster contributions to standardization.” Numerous activities have been undertaken by Global5G.org to further this mission.
A further goal was to provides an in-depth analysis of the 5G standardisation landscape with a focus on relevance to verticals and a mapping of 5G PPP contributions working in synergy with the PreStandardization WG. Over 295 standards contributions have been gathered from 5G PPP Phase 2 projects that directly or indirectly influence 5G standardisation and architectural developments. The standards contributions come in many formats including technical or specification documents, presentations, white papers, proof of concepts, interoperability tests, source code and so on. Both graphical analyses and full tabulations of contributions are provided.
Strategic Research and Innovation Agenda 2021-27 European Technology Platform NetWorld2020 “Smart Networks in the context of NGI”
"Currently, there is a wide acceptance that 5G networks will have a significant impact in the worldwide economic development and transform all aspects of everyday life. Even though 5G networks offer undeniable improvements over legacy networks, key findings suggest that European research activities in the communication networking sector need to continue at an increased pace. For this reason, we need to address several key challenges in a structured way so as to achievement maximum positive impact"
In a dynamic, fast paced and more increasing mobile digital world the importance of 5G as the "oxygen for digital ecosystems" cannot be emphasised enough. In relation to one horizontal technology alone, 5G is core to the automation achievable by the Internet of Things across a broad range of sectors which will can contribute an estimated $10 trillion economic impact by 2025. The Digital Single Market could contribute €415 billion per year to the European GDP but only if the availability of mobile broadband infrastructure co-evolves with increased economic growth and employment.
