RAN openness and intelligence for 5G/6G security

2022-04-06
When it comes to the security of 5G networks, most of the attention of researchers, engineers, and practitioners are focused on cybersecurity, although attacks on the software itself are not the only problem. This blog post discusses RAN-related aspects for 5G/6G security including architecture-related risks, cybersecurity best practices, MEC, and O-RAN security opportunities.

5G-Advanced: 3GPP Rel-18 SA2 Features

2022-01-11
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.

3GPP Rel-18: 5G-Advanced RAN Features

2021-12-21
3GPP Rel-18 is the first release of the 5G-Advanced standard. On the 17th of December 2021, 3GPP TSG RAN plenary (3GPP RAN TSG #94e) approved 28 Release-18 projects (i.e., Study- and Work-Items, SI/WI) with the following split among RAN groups: 12 RAN1-led projects, 10 RAN2-led projects, 5 RAN3-led projects, and 1 RAN4-led project. Those topics include AI/ML for NR and NG-RAN, NTN and MIMO enhancements, evolution for sidelink, UAV, RedCap, SON, QoE, XR services, to name a few. In this post, we elaborate on each of the approved projects entering 5G-Advanced standardization.

RAN Intelligent Controller (RIC): Overview, xApps, and rApps

2021-12-13
RAN Intelligent Controller (RIC) is to enable abstracting out part of functionality from the eNB or gNB that was traditionally hosted at the base station in the form of xApps or rApps in the O-RAN architecture. The functions, to which we relate here in the RAN domain include e.g., mobility management or interference management. The decisions are made in the xApps, and RIC then enforces policies towards the RAN elements and controls them using the open interface, namely E2. In this post, we elaborate on the RIC, its functional split, xApps, and rApps.

O-RAN Non-RT RIC: Architecture and rApps

2021-12-01
The goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, model management, and enrichment information to the Near-RT RIC function so that the RAN can be optimized. Non-RT RIC works within the management plane and operates on seconds and minutes timescale. In this post, we provide the architecture of the Non-RT RIC and discuss the example applications, called rApps.
