6G communication networks must be highly dependable due to the huge
number applications, services, and public infrastructures that will be
dependant on it. However, the integration of vast number of
technologies, ranging from physical layer up to the application layer,
and diverse services ranging from entertainment to mission critical
public services need investigation of the infrastructure from
dependability point of view. We take four dependability concepts such as
reliability, availability, safety and security, and discuss the
dependability of 6G networks. Since intelligence and distribution of
control functions and elements make the core of future networks,
specific diligence is given federated learning and edge intelligence.
This article, in summary, provides interesting insights into existing
challenges and advocates future research through highlighting the most
important research directions to make 6G dependable.
