Abstract: Over the past decade, Massive MIMO has gone from being a wild multi-antenna concept for improving the data rates in future cellular networks to mainstream technology. Base stations with 64 (or more) fully digital transceiver chains have been commercially deployed in several countries. Even the development of fully digital Massive MIMO arrays for mmWave frequencies is well underway. This is not the end of the MIMO 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. Among the different technologies, a promising one is represented by Cell-free Massive MIMO. This talk starts by giving a background of cellular Massive MIMO in 5G and by identifying the fundamental limits that call for a shift towards the cell-free paradigm. Next, we will introduce the foundations of User-Centric Cell-Free Massive MIMO and explain the benefits of the user-centric cell-free operation compared to conventional cellular operation. The key information-theoretic tools and signal processing techniques will be introduced with a particular emphasis on scalable implementation that guarantees feasible computational complexity and fronthaul in a large network with many mobile terminals.
