 Ultra Reliable and Low Latency Communication in 5G

The new wave of the technology revolution, named the fourth industrial revolution, is changing the way we live, work, and communicate with each other. In order to support unprecedented services and applications requiring lower latency, better reliability, massive connection density, and improved energy efficiency, the International Telecommunication Union (ITU) defined three representative service categories, viz., enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low latency communication (URLLC). Among three categories, physical layer design of the URLLC service is perhaps the most challenging and problematic since URLLC should satisfy two challenging requirements: low latency and ultra-high reliability. In this talk, I will explain the state-of-the-art overview of URLLC communications with an emphasis on physical layer challenges and solutions.


Byonghyo Shim received the B.S. and M.S. degree in Electrical Engineering from Seoul National University (SNU), Seoul, Korea, in 1995 and 1997, respectively, and the M.S. degree in Mathematics and the Ph.D. degree in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign (UIUC), Urbana, in 2004 and 2005, respectively. He industry experiences include LG Electronics, Texas Instruments, and Qualcomm. Since September 2014, he has been with the Dept. of Electrical and Computer Engineering, SNU, as a professor. Dr. Shim was the recipient of the M. E. Van Valkenburg Research Award from University of Illinois, Hadong Young Engineer Award from IEIE, and Irwin Jacobs Award from Qualcomm. He is an associate editor of IEEE Transactions on Signal Processing, IEEE Wireless Communications Letters, Journal of Communications and Networks, and a guest editor of IEEE Journal of Selected Areas in Communications.
