In this tutorial style talk, I will start with an introduction to major techniques to boosting capacity in 5G mobile communication systems. Then, I will introduce the entire process from theory to deployment, including theoretical performance analysis, large simulation experiments and prototyping, and their relationship in supporting the design of mobile communication systems to real implementations. Finally, as a case study, I will introduce our recent work on using stochastic geometry for performance analysis of ultra-dense small cell networks, particularly on analyzing the performance impact of Line-Of-Sight (LOS) and None-Line-Of-Sight (NLOS) transmissions. We show that as the density of base station (BS) increases from the current low value, there will a phase transition where the interference transits from mainly NLOS interference to mainly LOS interference. As a consequence, during a large range of the BS density, the overall network performance, measured by spectral efficiency and coverage probability, will actually decrease with the increase of the BS density.
