This tutorial will identify and discuss technical challenges and recent results related to the Artificial Intelligence (AI) based future wireless networks. The tutorial is mainly divided into four parts. In the first part, we will introduce future wireless networks and AI, discuss about the future wireless networks architecture, and provide some main technical challenges in AI based future wireless networks. In the second part, we will focus on the issue of AI based resource management in future wireless networks and provide different recent research findings that help us to develop engineering insights. In the third part, we will address the signal processing and PHY layer design of AI based future wireless networks and address some key research problems. In the last part, we will summarize by providing a future outlook of AI based future wireless networks.
Nowadays, the mobile network no longer just connects people but is evolving into billions of devices, such as sensors, controllers, machines, autonomous vehicles, drones, people and things with each other and then achieves information and Intelligence. From a planning and optimization perspective on the mobile network, this means that we also need a lot more flexibility to address these future needs.
Next-generation (B5G/6G) mobile networks are characterized by three key features: heterogeneity, in terms of technology and services, dynamics, in terms of rapidly varying environments and uncertainty, and size, in terms of number of users, nodes, and services. The need for smart, secure, and autonomic network design has become a central research issue in a variety of applications and scenarios. Intelligence (AI) and future wireless networks have attracted intense interest from both academia and industry to potentially improve spatial reuse and coverage, thus allowing cellular systems to achieve higher data rates, while retaining the seamless connectivity and mobility of cellular networks. However, considering the severe inter-tier interference and limited cooperative gains resulting from the constrained and non-ideal transmissions between adjacent base stations, a new paradigm for improving both spectral efficiency and energy efficiency through suppressing inter-tier interference and enhancing the cooperative processing capabilities is needed in the practical evolution of AI based future mobile networks.
This tutorial will identify and discuss technical challenges and recent results related to the AI based future mobile networks. The tutorial will introduce future mobile networks and AI, discuss about the future mobile networks architecture, AI based resource management, PHY layer design with AI and providing a future outlook of AI based future wireless networks.

Driven by an emerging use of flying platforms such as unmanned aerial vehicles (UAVs), drones and unmanned balloons in future network applications and the challenges that the 6G networks exhibit, the focus of this tutorial is to demonstrate the evolution of the flying platforms as a novel architectural enabler for radio access network (RAN) and their integration with the future cellular access and backhaul/fronthaul networks.These platforms are networked, flying and a potential way to offer high data rate, high reliability and ultra-low latent access and backhaul/fronthaul to future wireless networks. Such large scale deployable platforms and frameworks will guarantee the global information and communication requirements in future smart and resilient cities and solve the ubiquitous connectivity problems in many challenging network environments, e.g., coverage or capacity enhancements for remote or sparsely populated areas,social gathering, temporary health infrastructure (such as the ones being build during Covid-19 Pandemic in the UK) and disaster affected scenarios, etc. This tutorial will provide balanced coverage on recent trends, challenges and future research and development on the integration of flying platforms with the future wireless networks.
