Title: Several basic problems in designing 5G and future wireless systems

Time and Venue: July 21,09:30-10:30 N210

Speaker: Dr.Xue Feng(Santa Clara,CA,USA)

Abstract: This talk focuses on several challenging issues in the fourth-generation (4G) and emerging 5G cellular wireless systems, and tries to make connection to basic design and optimization problems in general complex dynamic systems.

We first briefly review a few new trends showing up during the development of 4G, e.g. heterogeneity, MIMO and intelligent mobile devices. Then we discuss the ‘wild’ scopes the emerging 5G tries to cover. This includes mmWave, ultra-dense networks, massive MIMO, real-time services, etc. We try to characterize the fundamental challenges and their connection to basic problems in complex dynamic systems, including information theory, topology control, adaptive system identification and network control over wireless.

Speaker Bio: Feng Xue is a senior research scientist at the Wireless Communication Research Lab, Intel Labs, USA. Except a short stint at the Qualcomm R&D center in southern California, he has been working on 4G/5G and device innovations at the Silicon Valley. He is also interested in fundamental research such as information theory, control and optimization in stochastic systems. Feng has published more than 30 papers and filed more than 60 patents, and he is also a co-author of the first book on wireless scaling laws. He got his PhD from the University of Illinois, Urbana-Champaign, MS from the Institute of Systems Science, CAS, and BS from Shandong University.
