Title : How to Bring 6G to Reality?
Abstract : Future wireless networks are expected be more than allowing people, mobile devices, and objects to communicate with each other. The sixth generation (6G) of mobile networks are envisioned to include high data rate applications and ultra-massive, connected things. This also includes bio and nano-internet of things (IoT) tele-operated driving, unmanned mobility, haptic communications, unmanned aerial vehicles, and many more. Given the size of nano-sensors, THz frequency is proposed to do various sensing activities at this scale. However, it will be ideal to use the same radio frequency for communications as well. Furthermore, THz is also proposed as an enabler of extremely high data rate applications in 6G communications. The talk will be focused on Terahertz antenna design, Reconfigurable Intelligent Surfaces (RISs) and its role for joint communication and sensing feature of 6G.

Title : Cell-free massive MIMO for next generation multiple access
Abstract : The next generation multiple access (NGMA) techniques are expected to achieve massive and ubiquitous access for a large number of devices and provide high spectral efficiency in ultra-dense networks. To meet these unprecedented mobile traffic demands, a paradigm shift from the conventional cellular networks towards distributed communication systems is required. Cell-free massive multiple-input multiple-output (CF-mMIMO) is considered as a practical and scalable embodiment of the distributed/ network MIMO systems, which inherits not only the key benefits from co-located massive MIMO systems, but also the macro-diversity gain from the distributed systems. In this presentation, we provide an overview of current research efforts on the CF-mMIMO systems and their promising future application scenarios including ISAC. Then, we elaborate on the new requirements for CF-mMIMO networks and propose a unifying framework for NGMA based on virtual full-duplex and CF-mMIMO.

Title : Waveform Design for Integrated Sensing and Communications (ISAC)
Abstract : A fundamental research problem in ISAC is how to efficiently developoptimal/good waveformsthat can be used for simultaneous sensing and communications. In the first part of this talk, I will introduce a novel multicarrier ISAC waveform having low peak-to-average power ratio property. We consider a flexible and generic ISAC structure in which a number of non-contiguous sub-bands for data transmission are located in alarge contiguous spectrum band. Optimization is carried out for those non-communication subcarrierswith the aid of the majorization-minimization method. In the second part, I will introduce several families of sensing sequences for low-complexity delay-Doppler estimation in ISAC systems. Fundamental limits and systematic constructions of these sequences will be presented.
