Motivation and Context

The deployment of every new generation of cellular networks is typically preceded by both an analysis of the issues affecting the current generation and the identification of new technological challenges. The importance of this step is evident at the dawn of the development of the Fifth generation (5G) network. One of the biggest concerns for both the telecommunication industry and the operators in view of 5G is to achieve the expected overall spectral efficiency enhancement, all the while minimizing both the additional operational/capital expenditure and the carbon footprint of the information and communication technology infrastructure. The development of new algorithms, resource management policies, transceivers and in general network technologies is seen as a necessary step to take to achieve the expected performance increase. As a matter of fact, such development will come at a non-negligible cost for operators. In this context, spectral and energy efficiency will be key metrics to assess the performance of the future network, whose deployment should be both spectral and energy efficiency aware. The reason is very simple and can be undertsood by taking a step back and focusing on the world's information and communication technology ecosystem as a whole. A mid–range estimate of its annual electricity consumption is around 1500 TWh. To contextualize this impressive figure, it is sufficient to consider that this quantity is actually equal to all the electric generation of Japan and Germany combined, or alternatively to the consumption of the global illumination system in 1985. As a matter of fact, ICT approaches 10\% of the current world electricity generation, or in other terms 150\% of what is generated for global aviation. In this tutorial, we start by providing an overview of these problems and discuss novel solutions and paradigms functional to achieve the expected future network performance and end-user quality-of-experience.

Structure and Content

This is an in-depth tutorial on recent trends and challenges for the deployment of future 5G wireless networks. In particular, it gives comprehensive and balanced coverage of emerging topics and state-of-the-art technologies that will drive the future network architecture, transceiver and algorithm design. Specific attention will be devoted to the potential application of such tools to achieve the spectral and energy efficiency improvement that is expected from 5G wireless networks. General features of this tutorial are the following:

• It presents a thorough review of the motivation, taxonomy and solutions to develop spectral and energy efficient 5G wireless networks.
• It introduces many state-of-the-art techniques, e.g. energy efficiency based on power control, cognitive interference reduction, resource allocation, network architecture and transceiver design, all framed in the context of future 5G networks.
• It presents a comprehensive and detailed comparative study which is supported by several simulations and illustrative examples on several network deployment configurations.
• The tutorial is supported by list of strong references which are most recent and highly cited in the relevant areas.
• The slides present a contemporary tutorial type presentation in order to make it understandable to most of the audience.
• The slides include excellent graphical illustrations to show the technical description of the system and its implementation.

Interestingly, the content of the tutorial and its maturity, is such that the tutorial itself can occupy either a half-day (3 hours) or a full-day (6 hours) slot, depending on both the available slots and the decisions of the organizing committee. In this sense, our proposal is flexible and provides details about both possibilities. In particular, we start by describing the structure of the half-day version.
