This book chapter describes the research targets of Tactile Internet with Human-in-the-Loop (TaHiL) in the field of Communications and Control. Communications describes the research field of transport, storage, and computing of information and is tailored to the application of control use cases for quasi-real-time, low-latency Cyber-Physical System (CPS) as well as the multimodal feedback for human-machine interaction. The research is adapted to the needs of other research fields and derives its technical parameters from them as it relates to latency, resilience, massiveness, heterogeneity, energy, and security. The fundamental research topics for communications and control are presented. Furthermore, the core technologies, such as compressed sensing, network coding, functional compression, and machine learning, are introduced and put into context.
