Aspects of Time and Space in Wireless Connectivity beyond 5G and 6G

Prof. Petar Popovski
Department of Electronic Systems, Aalborg University, Denmark

Wireless connectivity augments human capabilities beyond their natural domain, enabling operation and interaction with objects and subjects placed within an extended space-time domain. This talk will highlight aspects of time and space as these two basic physical notions get intertwined with the digital wireless communication systems beyond-5G/6G. In terms of time, the talk will present the general concept of timing in wireless communication systems and networks and its relation to effective information generation, processing, transmission, and reconstruction at the senders and receivers. Starting from the focus on latency, a specific instance of timing being in the focus of 5G, the talk will present a statistical framework of timing requirements in wireless systems. The timing framework subsumes both latency and Age of Information (AoI) and applied to various communication models, such as consensus or distributed learning/inference. In terms of space, wireless environments evolve towards becoming intelligent and reconfigurable. The talk will discuss the communication modeling aspects of reconfigurable wireless environments. Finally, leveraging the ambiguity of the term “space”, the talk will provide a perspective on non-terrestrial/satellite networks and their role in future wireless connectivity.
