W3: Beyond Massive MIMO – What is next?

Workshop Organizer: Luca Sanguinetti, University of Pisa, Italy
Workshop Organizer: Merouane Debbah, Technology Innovation Institute, Abu Dhabi

Abstract: Multiple antenna technologies have attracted much research interest for several decades and have gradually made their way into mainstream communication systems. The latest instantiation of multiple antenna technologies is Massive MIMO, which became a reality in 5G. In a few years, Massive MIMO with fully digital transceivers will be a mainstream feature at both sub-6 GHz and mmWave frequencies. However, this is not the end of the multiple antenna technologies development, but only the end of the beginning. As access to wireless connectivity becomes critical in our everyday lives, our expectations of ubiquitous coverage and service quality continue to grow. It is thus time for the research community to look for new multiple antenna technologies to meet the immensely higher data rate, reliability, and traffic demands in the beyond 5G era. Radically new approaches are required to achieve orders-of-magnitude improvements in these metrics. There will be large technical challenges, many of which are yet to be identified.
This workshop aims at bringing the researchers and practitioners interested in multiple antenna technologies together to address the topic, present their novel solutions, and discuss technical challenges. The authors are invited to submit their original and unpublished work.
