This document provides an overview of the CS590 course "Embracing 5G and Beyond 5G" taught by Professor Chunyi Peng at Purdue University in Fall 2017. The course aims to help students understand critical demands in 5G networks and learn about state-of-the-art 5G technologies. It will consist of lectures, student paper presentations, and a team-based research project. Students are expected to gain experience in mobile networking research skills and produce publishable project results. The course syllabus outlines grading criteria and expectations for class participation, homework assignments, presentations, and the semester-long research project.

CS590 (Peng) 10

11. In-Class Presentation
& Reading Assignments
• Select one paper from the reading list (or
under my approval)
• Signup in advance
• In-class presentation
– 25-30 min presentation
– Q&A + in-class discussion
• Paper summary: select three out of the
reading list (invalid after in-class presentation)
CS590 (Peng) 11

12. How to Summarize a Paper?
• From four aspects
– 3 strong points: 3 most important things stated by
the paper
• Could be combination of motivations, observations,
interesting designs, or clever implementations (1) from
the author’s perspective at the time; (2) your
perspective with the benefit of hindsight
– 1 or more weakness: what is the single most
glaring deficiency?
• Design flaws, poorly designed experiments, narrow-
scoped main idea, weak applicability, …
CS590 (Peng) 12

13. More on Paper Summary
• 1+ key assumption/observation that led to the
research
– What were the key observations?
– Where did the observation/assumption come from?
• Personal experience, or work environment, …
• 1+ core risk/obstacle
– What are they to prevent the research from
successful?
– Were the authors aware of them? Are these obstacles
eventually overcome?
• Optional: what if you were the author
CS590 (Peng) 13

14. Course Project (1/3)
• Several topics to be distributed
– from the list or come up with your own
• Project scope (on mobile networking)
– Apps: emerging issues for 5G apps (e.g., scalability,
delay, energy, security etc)
• Understand the requirements in support of new apps
• Disclose and quantify the (unanticipated) issues
• Explore solution ideas
• Design, implement and evaluate the new solution
• Example: massive IoT support (pain for massive connectivity,
emerging security risks, issues still unresolved by recent
proposals)
• Example: realtime support for VR/AR/autonomous driving
(latency is the key)
CS590 (Peng) 14

15. Course Project (2/3)
– Technology (wireless advances, architecture,
radio/core, SDN/NFV, protocol)
• Build a (simplified) 5G prototype or simulator
• Re-architecture: NFV for 5G (redefine and split
functions), mobile edging computing
• Redesign protocols: simplified signaling protocols
• Augment intelligence at end devices (data-driven) via
MobileInsight
– Enable runtime network analytics at devices
