Time 10:00 – 10:40 (JST)

Theodore S. Rappaport
Professor / Founding Director, NYU WIRELESS
David Lee/Ernst Weber Professor of Electrical Engineering New York University

Title: The Impending Data Explosion in Wireless Communications



Abstract: This talk explores the amazing growth in data rates and download speeds over the past decade in wireless communications, and demonstrates how the three engineering pillars of 5G, massive-mimo, small cells, and millimeter wave communications, will bring forth far greater growth than anyone could imagine today, eventually enabling "wireless cognition" and "information showers," where real time over-the-air-data transmissions occur at the rate of human thinking.

Biography: Theodore S. Rappaport is the David Lee/Ernst Weber Professor at New York University (NYU) and holds faculty appointments in the Electrical and Computer Engineering Department, the Courant Computer Science Department, and the NYU Langone School of Medicine.

Title: Toward making the world more resilient: a work on resilient communication and information sharing platform and its deployment


Abstract: As natural disasters occur much more frequently and/or are more severe than expected year by year, “resilience” has been gaining greater attentions. The United Nations’ SDGs include building “resilient” infrastructure (Goal 9) and making cities and human settlements “resilient” (Goal 11). Future information and communications systems are expected to be more resilient, providing resilient information and communications services to make the society more resilient. Resiliency is a key feature of Beyond 5G and 6G. There are issues of not only the research and development of technologies regarding resilience but also making the technologies for practical use and deploying them as systems in society. Our work will be presented in this talk. NerveNet is an Internet-independent, resilient, secure, information sharing, and communication platform technology. You can easily deploy your own NerveNet using Linux PCs on the market as basestations and using various transmission systems on the market to interconnect them, configuring a network in any topology including mesh for obtaining resistance to failures (resilient networking). The basestations cooperatively perform distributed database, providing data applications to users without the Internet (resilient edge could). With these features, it is being used in some locations not only in Japan but also overseas such as Cambodia and Nepal as smart, resilient village networks in rural areas to offer digital contents to students and residents. Let’s come into resilient ICT area and have collaborations together!

Biography: Masugi Inoue graduated from Kyoto University in 1992 and received his Dr. Eng. degree from The University of Tokyo in 1997. After he joined the Communications Research Laboratory (CRL), which was reorganized as NICT in 2004, he contributed to develop the world fastest WLAN in MM-wave bands, common-signaling MIRAI architecture in heterogeneous networks for context-aware services in the 4G era, ID-locator split architecture (HIMALIS) for future Internet, etc. He has been working on a resilient platform system called NerveNet, which has been deployed and tested/operated in domestic and overseas locations. From 2016 to 2021, he worked on international cooperation and operated ASEAN IVO, Japan-US (JUNO) and Japan-EU (HORIZON) Joint Research Programs. He has been in his current position since April this year. He was a visiting researcher at Polytechnic University (now NYU WIRELESS), New York, in 2000. He served as Chairman of the Technical Committee on Mobile Network and Applications (MoNA, now merged into SeMI) in the IEICE Communications Society.

He is a fellow of IEICE and a member of IEEE.

Time 17:00 – 17:40 (JST)

Tomoaki Ohtsuki
Professor, Keio University

Title: Machine Learning for Intelligent Wireless Communications



Abstract: With the rapid development in AI and machine learning (ML), future wireless communication systems will have much more intelligence. For problems that can be accurately modeled, traditional algorithms show good performance and efficient solutions on partially convex problems. However, for some non-convex problems, existing algorithms usually obtain more efficient solutions while allowing a certain performance loss. At this time, ML is used to mine the parameter information of the known structure algorithm from the obtained data samples, to improve the convergence speed of the algorithm and the performance of the algorithm. However, a large number of 5G and B5G scenarios cannot be modeled by exact mathematical models such as some efficiency and latency optimization problems, resulting in the inability to obtain an accurate algorithm structure. In this case, the artificial neural networks (ANNs) including deep neural network (DNN), convolutional neural network (CNN), and so on are used to parameterize the model or algorithm. These methods that obtain model or algorithm features from massive amounts of data rather than based on pre-established rules are generally called data-driven. This talk introduces ML based intelligent wireless communications, mainly focusing on the research and application of ML in the physical layer.

Time 11:00 – 11:40 (JST)

Etsushi Yamazaki
Network Innovation Laboratories, NTT

Title: Recent R&D efforts in digital coherent optical transmission technology

Abstract: Digital coherent optical transmission technology is indispensable for large-capacity optical transmission systems, and its typical signal processing and transceiver configuration will be introduced. The innovative modulation and coding schemes achieve better transmission performance, enabling transmission over a long- and ultra-long-haul distance for terrestrial and under-sea systems at a capacity beyond 100 Gbps. At the same time, for data center interconnection networks, there is a strong demand for an increase in transmission capacity. Therefore, a modulation size is increasing up to more than 64-point quadrature amplitude modulation even in the commercial system. At the same time, demand for Baudrate increase is remarkable, and Baudrates higher than 100Gbaud are demonstrated in the recent high capacity experiments. There, the sophistication of signal distortion compensation is also an important technology. In addition, to improve the system integration density, it is required to realize high throughput such as 400G with low power consumption, and recent trends in power efficiency will be covered.
