TL;DR: In this article, the backhaul network capacity and energy efficiency of ultra-dense cellular networks are investigated to answer how much densification can be deployed for 5G ultra-density cellular networks.

TL;DR: The wireless backhaul traffic in two typical network architectures adopting small cell and millimeter wave communication technologies is analyzed and the energy efficiency of wirelessBackhaul networks is compared for different network architectures and frequency bands.

TL;DR: In this article, the issues involved in the design of antenna array architecture for future 5G mmw systems, in which the antenna elements can be deployed in the shapes of a cross, circle, or hexagon, are discussed, in addition to the conventional rectangle.

TL;DR: It is shown that although the existing standardized point-to-point MIMO channel models can be applied to a certain extent to model cooperative M IMO channels, many new challenges remain in cooperative MIMo channel modeling, such as how to model mobile-to -mobile channels, and how to characterize the heterogeneity and correlation of multiple links at the system level appropriately.

TL;DR: New spatial spectrum and energy efficiency models for Poisson-Voronoi tessellation (PVT) random cellular networks and a Markov chain based wireless channel access model are proposed and analyzed.
