5G communications

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.

Summary
This Recommendation provides requirements, architecture, components and related sequence diagrams which together comprises an architecture framework for autonomous networks.

The scope of this Recommendation includes:

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.​

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. You can find the document at: https://datatracker.ietf.org/doc/draft-bagnulo-congress-cci/

Low Latency Low Loss Scalable throughput is a technology a novel technology that allows to significnatly reduce the queueing delay and achieve a high throughput. Multiple networks are adopting and its usage for 5G netwokrs are being considered.

The standards composing L4S have been recently published by the IETF:

- RFC 9330: Low Latency, Low Loss, and Scalable Throughput (L4S) Internet Service: Architecture. https://datatracker.ietf.org/doc/rfc9330/

This contribution provides recommendations for satellite ephemeris in active and idle/inactive mode operations. This study's prepared for the 3GPP RAN2 Working Group #119-e meeting. You can also reach the contribution from https://www.3gpp.org/ftp/tsg_ran/WG2_RL2/TSGR2_119-e/Docs/R2-2208641.zip

The attached contribution discusses idle and connected mode mobility for IoT NTN in the 3GPP RAN2 Working Group 119-e meeting. You can also reach the contribution from https://www.3gpp.org/ftp/tsg_ran/WG2_RL2/TSGR2_119-e/Docs/R2-2208146.zip 

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.

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.
