SUMMARY:Near-Field Communications: What Will Be Different?
DESCRIPTION:In this talk\, the design dilemma of “What will be different between near-field communications (NFC) and far-field communications (FFC)?” is discussed from four perspectives. (1) From the channel modelling perspective\, the differences between near-field and far-field channel models are discussed. (2) From the performance analysis perspective\, analytical results for characterizing the degrees of freedom and the power scaling laws in the near-field region are provided. (3) From the beamforming perspective\, the features of far-field beamsteering and near-field beamfocusing are compared. A couple of new beamforming structures for NFC are also introduced. (4) From the application perspective\, several new designs are discussed in the context of promising next-generation technologies in NFC. Finally\, research opportunities and problem are discussed. \nBiography of the speaker: \nYuanwei Liu is an Associate Professor with the School of Electronic Engineering and Computer Science\, Queen Mary University of London. His research interests include next generation multiple access\, integrated sensing and communications reconfigurable intelligent surface\, and near-field communications. His research attract over 20\,000 Google Scholar citations. He is listed as one of 35 Innovators Under 35 China in 2022 by MIT Technology Review and a Web of Science Highly Cited Researcher since 2021. He serves as an IEEE Communication Society Distinguished Lecturer\, an IEEE Vehicular Technology Society Distinguished Lecturer\, the academic Chair for the Next Generation Multiple Access Emerging Technology Initiative\, the rapporteur of ETSI Industry Specification Group on Reconfigurable Intelligent Surfaces\, and the UK representative for the URSI Commission C on Radio communication Systems and Signal Processing. He received IEEE ComSoc Outstanding Young Researcher Award for EMEA in 2020. He received the 2020 IEEE Signal Processing and Computing for Communications (SPCC) Technical Committee Early Achievement Award\, IEEE Communication Theory Technical Committee (CTTC) 2021 Early Achievement Award. He received IEEE ComSoc Outstanding Nominee for Best Young Professionals Award in 2021. He is the co-recipient of the Best Student Paper Award in IEEE VTC2022-Fall\, the Best Paper Award in ISWCS 2022\, the 2022 IEEE SPCC-TC Best Paper Award and the IEEE ICCT 2023 Best Paper Award. He serves as the Co-Editor-in-Chief of IEEE ComSoc TC Newsletter\, an Area Editor of IEEE Communications Letters\, an Editor of IEEE Communications Surveys & Tutorials\, IEEE Transactions on Wireless Communications\, IEEE Transactions on Vehicular Technology\, and IEEE Transactions on Network Science and Engineering. He serves as the (leading) Guest Editors for Proceedings of the IEEE/IEEE JSAC/JSTSP/Network/TGCN.
