5G Mobile
Communications

II of this book presents new transmission and design techniques for
5G networks with a focus on physical-layer enabling techniques. It contains 11
chapters.
The chapter “Massive MIMO Communications” argues that every new network
generation needs to make a leap in area data throughput, to manage the growing
wireless data traffic. Massive MIMO technology can bring at least tenfold improve-
ments in area throughput by increasing the spectral efficiency (bit/s/Hz/cell) while
using the same bandwidth and density of base stations as in current networks.
These extraordinary gains are achieved by equipping the base stations with arrays
of a hundred antennas to enable spatial multiplexing of tens of user terminals.
