TL;DR: This paper extends the popular Wireless World Initiative for New Radio (WINNER) channel model with new features to make it as realistic as possible and can accurately predict the performance for an urban macro-cell setup with commercial high-gain antennas.

TL;DR: The main objective of this paper is to present major challenges regarding the fifth generation (5G) mobile communications propagation modelling work in the European 7th framework project METIS (Mobile and wireless communications Enablers for the Twenty-twenty Information Society).

TL;DR: Comparisons of simulation and measurement results show that the coefficients of the polarized LOS channel can be predicted very well by the new method, and this increase in modeling accuracy is an important feature for many applications such as heterogeneous networks, space-to-ground satellite communications, and cooperative communications.

TL;DR: Four selected GTT solutions are introduced, focusing on how they utilize the degrees of freedom in different resource domains, as well as how they balance the tradeoff between energy and spectrum efficiency.

TL;DR: This paper introduces the key aspects of a new channel model based upon the Wireless World Initiative New Radio (WINNER)+ channel model for wireless channels in heterogeneous scenarios (e.g. indoor, outdoor and satellite scenarios).
