#ThinkSix Tech Talk: AI in wireless communications – Enhancing CSI feedback with ML

Join Rohde & Schwarz experts Andreas Oeldemann and Andreas Roessler as they continue their discussion of AI in wireless communications. The first episode of this series provided an overview of artificial intelligence (AI) and machine learning (ML) in today’s wireless communications landscape, with a focus on pilot use cases in 5G-Advanced.

This second installment is all about using ML to enhance channel state information (CSI) feedback - the only two-sided pilot use case for AI/ML in 5G-Advanced. In this scenario, the ML model runs partially in two entities, one on the user equipment (UE) side and the other on the network side. The two Andreases also review the current status of AI in 3GPP and provide insights into a recent interoperability testing milestone, achieved in partnership with Qualcomm Technologies.

Highlights of this session include:

• Current status of AI/ML pilot use cases in 5G-Advanced
• Two-sided model use case of ML-based CSI feedback enhancement with a focus on compression
• Joint demonstration with Qualcomm Technologies at Mobile World Congress Barcelona
• Outlook of ML-based CSI feedback enhancement for a future 6G standard
