2nd Training School

COST CA20120 - INTERACT Training School:

Open-RAN networks: from theory to implementation

5th-7th July 2022

Poznań, Poland


Open RAN is a recent trend in the telecommunications market (especially in the 5G area), aiming at the realization of the following key objectives:

  • splitting of a base station into several functional components, including central unit (CU), distributed unit (DU), and a remote unit (RU);
  • opening interfaces to enable interoperability (especially Open Fronthaul);
  • disaggregating software from hardware in the RAN domain;
  • introducing advanced automation into the RAN system by means of an abstracted entity to manage the radio networks, i.e., RAN Intelligent Controller (RIC), which serves as a platform for xApps (optimization applications in the RAN domain) and rApps (optimization applications in the management plane) using AI/ML.

The participants of the school will have the opportunity to deepen their knowledge and experience in various domains of Open RAN. These include the discourse on the evolution of the cellular network architecture from regular to virtualized and open one and the discussion on Open-RAN architecture (modules, interfaces, with particular attention put on intelligent controllers). Next, the ongoing world initiatives (such as O-RAN Alliance, ONF/SD-RAN, TIP/RIA) will be overviewed. Moreover, opportunities and challenges of the Open RAN approach will be presented together with the analysis of the ongoing trials and implementations. The school will be interactive, allowing the participants to join the hands-on part devoted to the demo xApp implementation.
