smart healthcare and the focus towards artificial intelligence providing solutions to many computational challenges and efficient resource allocation. 5G technology would revolutionize the way we use healthcare services and would lead to better and fair allocation of healthcare services in society. Chapter 2 covers advances of 5G wireless communication systems in healthcare informatics. The healthcare sector is a very important aspect of the 5G communi- cation system. H-IoT will play a very important function in shaping the future of human beings in healthcare 5.0. A 5G communication system with BSN will lead to personalized well-being in future. The various communication layers and the Preface corresponding technologies help us to understand the H-IoT. The H-IoT faces various security challenges. The solutions of these security issues are proposed by various researchers. Numerous communication protocols are proposed in application, ser- vice, and in the infrastructure of H-IoT. The use of H-IoT devices and diagnostic tools will increase in the future very rapidly. H-IoT is an integral part of the 5G communi- cation network. Chapter 3 covers beamforming in massive MIMO communications for 5G tech- nology. In this chapter, authors provide a tutorial of modeling and analyzing signifi- cant key performance indicators (KPIs) of massive multi-input multi-output (MIMO) systems in a downlink Rayleigh fading channel. Chapter 4 covers 5G-enabled network technology trends for smart healthcare systems. The chapter provides a comprehensive analysis of 5G-supported smart healthcare solutions on the IoT. By classifying existing literature, a framework for 5G smart healthcare is proposed. Finally, with the IoT and 5G smart healthcare solution, this chapter address many open problems and study challenges. Chapter 5 covers practical considerations relating to non-orthogonal multiple access transmission for 5G technology. It deals with investigating practical NOMA transmission using a variety of approaches. First, authors construct
