Interference management in LTE

Lecturers: Guowang Miao and Ki Won Sung

Prerequisite: Interference management (Chapter 7)

Interference statistics in Cellular Radio Systems

• In Lab 2, students will get acquainted with a MATLAB-based network simulator called RUNE, which they will use to analyze blocking and interference statistics in a cellular network.
• Lab 2 will help students in developing skills to perform simulations to answer complex problems which would be impractical to solve analytically, and also in developing a better understanding of the fundamental tradeoff between coverage and capacity which exists in wireless networks.

Chap 6 Transmit Power Control: Ex 6.5, 6.6

Chap 7 Interference Management: 7.1

Chap 8 Mobility and Handover: Ex 8.1 and 8.2

• In Lab 3, students will work on a poorly designed cellular network to solve coverage and capacity problems using a state-of-the-art cellular network planning tool, Mentum CellPlanner.


• This lab will illustrate many of the concepts that the students learn in the course, for example, received signal power, blocking probability, SINR, etc., using a professional cellular network planning tool.
