On the Potential of Using Sub-THz Frequencies for Beyond 5G

Autor: Tervo, Oskari, Nousiainen, Ilmari, Nasarre, Ismael Peruga, Tiirola, Esa, Hulkkonen, Jari

This paper studies the potential of using above 71GHz frequencies for 5G-Advanced or later in 6G. More specifically, the focus is to analyze what could be needed in terms of waveform and numerologies. The results suggest that higher baseline subcarri

Future telecommunication systems need to support a discovery function, enabling all network nodes to discover each other directly over the air. In addition to discovery in traditional access point-to-user equipment (AP2UE) links, there is a need to s
