seminar on User Scheduling and Beamformer Design in Massive MIMO and mmWave Massive MIMO


User scheduling is one of the main issues in wireless cellular networks where a base station serves multiple users in each cell. User scheduling provides multi-user diversity gains to wireless data networks, where arrival of data packets is bursty and certain delay can be tolerated at users, and was widely investigated for 3G high-speed downlink/uplink packet access (HSDPA/HSUPA). Furthermore, 4G cellular networks adopted the multiple-input multiple-output (MIMO) technology, which provides spatial diversity and multiplexing gains based on multiple antennas, and the MIMO technology is further evolving into massive MIMO in the sub-6 GHz band and in the millimeter-wave (mmWave) band for 5G. The introduction of MIMO provides additional degree-of-freedom for user scheduling by simultaneously supporting multiple users in the spatial domain at the same time and frequency.

User Scheduling and Beamformer Design in Massive MIMO and mmWave Massive MIMO


Youngchul Sung received B.S. and M.S. degrees from Seoul National University, Seoul, Korea, in Electronics Engineering in 1993 and 1995, respectively. After working at LG Electronics Ltd., Seoul, Korea, from 1995 to 2000, he joined the Ph.D. program and received the Ph.D. degree in Electrical and Computer Engineering from Cornell University, Ithaca, NY in 2005. From 2005 until 2007, he was a senior engineer in the Corporate R & D Center of Qualcomm, Inc., San Diego, CA, and participated in design of Qualcomm’s 3GPP R6 WCDMA basestation modem. Since 2007 he has been on the faculty of the School of Electrical Engineering in KAIST, Daejeon, Korea and he is currently a tenured associate professor at KAIST.
Dr. Sung’s research interests include wireless communication, statistical signal processing and inference, and asymptotic statistics with applications to wireless communications and related areas. Dr. Sung is currently a senior member of IEEE, chair of IEEE Communications Society, Asia Pacific Board (IEEE ComSoc APB),
