In this post we dig into the technical details of the Traffic Steering xApp implementation using A1 Policy Control on ONF's SD-RAN. We discuss the concept, triggers, implementation details and example operation along with a demo video.

Rimedo Labs has integrated an xApp into the SD-RAN RIC from ONF to demonstrate the operation of the A1 interface as defined by the O-RAN Alliance. This Is the first xApp integrated with the ONF’s SD-RAN platform utilizing the A1 interface for policy control. As part of the ONF’s SD-RAN project, the joint collaboration supports a broad range of automation services in the form of software services, called xApps by O-RAN, that run on the RAN intelligent controller (RIC).

RAN Intelligent Controller (RIC) is one of the key elements in the O-RAN architecture, which allows feeding an „external” intelligence into the operations of the radio network. It creates a platform for which the software companies could provide per-use case AI-powered algorithms to make way for, among others, radio resources usage or procedure optimizations. This whitepaper provides an overview of the RIC, discusses its functional split into Non-Real-Time and Near-Real-Time entities along with the concept and examples of rApps and xApps.

This post presents a more detailed description of the sidelink radio interfaces proposed in LTE-V2X (Release 14/15) and its successor – NR-V2X. The focus will be mostly on the physical layer and radio resource allocation aspects, with some information on the synchronization possibilities and Quality-of-Service (QoS) management, also provided.

On the 20th of December 2021, 3GPP SA TSG approved a total of 28 WIs/SIs for the SA2 Rel-18 at the SA plenary meeting #94e. 3GPP Rel-18 is the first release of the 5G-Advanced standard. The approved projects include TSN, NW slicing, support for edge computing, NW automation, location services, AI and ML-based services, XR services to name a few. In this post, we elaborate on each of the approved WI/SI entering 5G-Advanced standardization.

Rimedo Labs joins forces with the Military institute of Communications (Wojskowy Instytut Łączności), Politechnika Poznańska and Grandmetric to work on 5gSTAR, an innovative research project funded by Narodowe Centrum Badań i Rozwoju on cyber-security in 5G radio
