Talk Title:
PReconfigurable Intelligent Surface-Empowered Communications for 6G Wireless Networks
Talk Abstract:
Signal processing and communication communities have witnessed the rise of many exciting communication technologies in recent years. Notable examples include alternative waveforms, massive multiple-input multiple-output (MIMO) signaling, non-orthogonal multiple access (NOMA), joint communications and sensing, sparse vector coding, index modulation, and so on. It is inevitable that 6G wireless networks will require a rethinking of wireless communication systems and technologies, particularly at the physical layer (PHY) since the cellular industry reached another important milestone with the development of 5G wireless networks with diverse applications. Within this perspective, this talk aims to shed light on the rising concept of reconfigurable intelligent surface (RIS)-empowered communications towards 6G wireless networks. We discuss the recent development in the field and put forward promising candidates for future research and development. Specifically, we put our emphasis on active, transmitter-type, transmissive-reflective, and standalone RISs, by discussing their advantages and disadvantages compared to reflective RIS designs. Finally, we also envision an ultimate RIS architecture, which can adjust its operation modes dynamically, and introduce the new concept of PHY slicing over RISs towards 6G wireless networks.
