The aim of this book, the first of two volumes, is to present selected research that has been undertaken under COST Action IC0902 ‘‘Cognitive Radio and Net- working for Cooperative Coexistence of Heterogeneous Wireless Networks’’ (http://newyork.ing.uniroma1.it/IC0902/). COST (European Cooperation in Sci- ence and Technology) is one of the longest-running European frameworks sup- porting cooperation among scientists and researchers across Europe.

To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation (5G) mobile communication systems has been undertaken in recent years. It is expected that the spectral and energy efficiencies in 5G mobile communication systems should be ten-fold higher than the ones in the fourth generation (4G) mobile communication systems. Therefore, it is important to further exploit the potential of spatial multiplexing of multiple antennas. In the last twenty years, multiple-input multiple-output (MIMO) antenna techniques have been considered as the key techniques to increase the capacity of wireless communication systems. When a large-scale antenna array (which is also called massive MIMO) is equipped in a base-station, or a large number of distributed antennas (which is also called large-scale distributed MIMO) are deployed, the spectral and energy efficiencies can be further improved by using spatial domain multiple access. This paper provides an overview of massive MIMO and large-scale distributed MIMO systems, including spectral efficiency analysis, channel state information (CSI) acquisition, wireless transmission technology, and resource allocation.

This paper covers the keynote address delivered by the Chairman of the COST Action 285 at the Symposium. It outlines the studies undertaken by the members of the Action with the objective of enhancing existing modeling and simulation tools and to develop new ones for research in emerging multiservice telecommunication networks. The paper shows how the scope of COST Action 285 has been enriched by the contributions made at the Symposium.
