Abstract

With the increase in data traffic driven by a new generation of wireless devices, data is expected to overwhelm cellular network capacity in the future. Heterogeneous cellular networks are a comprehensive approach to provide high cellular network capacity by overlaying conventional macrocell cellular architecture with heterogeneous architectural features such as small cellular access points (picocells and femtocells), low-power fixed relays, and distributed antennas. Heterogeneous cellular networks are expected to achieve higher data rates and better coverage by exploiting spatial reuse, while retaining at the same time the seamless connectivity and mobility of cellular networks.

Inspired by the attractive features and potential advantages of heterogeneous cellular networks, their development and deployment is gaining momentum in the wireless industry and research communities during the last few years. It has also attracted the attention of standardization bodies such as 3GPP LTE-Advanced. However, heterogeneous cellular networks also come with their own challenges, and there are significant technical issues that still need to be addressed for successful rollout and operation of these networks.

In this tutorial, we will introduce some of the main challenges in small cell networks and discuss some recent results related to the fundamental understanding and design of small cell networks. In conclusion, we will provide some discussions of future research topics related to this area and how small cell networks play a role in 5G.

Type of Tutorial

Half-day

The tutorial is intended for the generally knowledgeable individual working in the field of wireless communications and networking with some background in probability theory and signal processing. It is also suitable for students and researchers who are interested to learn about small cell networks and 5G.

Objective and Motivation

The main objective of this tutorial is to introduce small cell networks and some recent research advances to academic and industrial researchers. At the same time, this tutorial will introduce stochastic geometry to academic and industrial researchers, especially as an effective and suitable mathematical and engineering tool to understand and better design small cell networks. Lastly, the tutorial will identify and discuss technical challenges and recent results related to small cell networks.

The tutorial is mainly divided into two parts. In the first part, we will introduce small cell networks, discuss some of the main technical challenges, and give an overview to some mathematical tools that we apply to design small cell networks. In the second part, we will focus on the fundamental design of small cell networks and provide different recent research findings that help us to develop engineering insights.
