CSC 591 608 LTE and 5G Communications

3 Credit Hours

(also offered as ECE 578)

The course provides an introduction to the theoretical and practical aspects of Long Term Evolution (LTE) technology and beyond. A basic understanding of digital communication systems and radio access networks are required. Six main topics will be studied: 1) Network architecture and protocols, 2) Physical layer for downlink, 3) physical layer for uplink, 4) practical deployment aspects, 5) LTE-Advanced, and 6) 5G communications.


Although not required, students are advised to have prior knowledge gained from Computer Networks (NC State ECE 570) or Wireless Communication Systems (NC State ECE 582) before taking this course.

Course Objectives

  • To understand the overall network architecture and protocols for LTE networks, including control plane protocols and user plane protocols;
  • To learn the downlink physical layer of LTE systems in detail, including: how OFDMA technology is adopted in LTE; synchronization and cell search procedures; reference symbols and channel estimation; use of control/data channels in LTE downlink; multiple antenna techniques; scheduling and interference coordination; and broadcast operation.
  • To learn the uplink physical layer of LTE systems in detail, including: uplink PHY design in LTE; uplink reference signal design and physical channel structure; random access for uplink; and uplink transmission procedures (power control and timing alignment).
  • To understand various practical deployment aspects of LTE networks, including: user equipment positioning; radio propagation characteristics; radio resource management; small cell deployment in LTE; and self optimizing network (SON) features in LTE.
  • To understand the basic features of LTE–Advanced networks, including: carrier aggregation, MIMO enhancements, relaying, and interference coordination enhancements.
  • To have a high level understanding of the basic features of emerging 5G wireless networks, including mmWave communications, massive MIMO, machine type communications, device-to-device and vehicle-to-vehicle communications, and tactile (low latency) Internet.

Course Requirements

Homeworks*: 35%
Course Project: 30%
Final Exam: 35%

* Homeworks will include multiple choice questions, concept/math problems, and Matlab assignments. The Matlab assignments will be based heavily on the LTE System Toolbox and Communication Toolbox in Matlab, both available to NCSU students through The Virtual Computing Lab (VCL).
