Short Courses on Wireless and 

Mobile Communications 2023

by Oh-Soon Shin, Soongsil University, Korea

  In the early 1990s, domestic researchers and industry experts foresaw the rapid growth of the mobile communication industry, which led to the establishment of the KICS Mobile Communications Research Group in 1993, later rebranded as the Mobile Communications Society. Since its inception, the society has actively engaged in research exchange and educational activities in the field of wireless and mobile communications. As part of its educational initiatives, the society has organized short courses on “Wireless and Mobile Communications” annually, which cover diverse topics such as the latest technologies, applications, services, standardization, and policies related to wireless and mobile communication systems.

  Held online from August 16 to 18, 2023, this year’s event witnessed the successful participation of a total of 110 researchers and students, concluding with success. The short courses examined fundamental and essential topics, ranging from the foundational technologies of wireless and mobile communication systems to the applications of artificial intelligence in sixth-generation (6G) communications.

  On the first day, Prof. Wonjae Shin from Ajou University delivered lectures on the fundamentals of wireless and mobile communication theory, which covered the characteristics of wireless channels, cellular systems, and the concept of multiple access. Prof. Sang-Woon Jeon from Hanyang University introduced the overall theory and physical layer technologies of digital communication systems. On day two, Prof. Namyoon Lee from Korea University addressed the latest technologies in multiple antennas, which is a key technology for enhancing spectral and energy efficiencies in wireless communication systems. Prof. Songnam Hong from Hanyang University introduced optimization theory, which is crucial for the development of wireless communication technologies. On the final day, Prof. Woong-Hee Lee from Korea University and Prof. Howon Lee from Hankyong National University explored the applications of machine learning technologies in the physical and medium access control layers. Lastly, Prof. Byonghyo Shim from Seoul National University introduced various cutting-edge physical layer technologies capable of enabling 6G communications.

  The short courses this year not only covered the fundamental communication theories but also delved into the applications of machine learning in communications and the latest research topics related to 6G. The short courses are expected to maintain a central role in 6G mobile communication research and education in the future.
