Hi All.
Does anyone know which radio access technology will be used for 6G?
I understand that spectral efficiency of 6G must be 10x of 5G.
If I understand, L1 research work still going on.
Nothing concrete came out yet.
10x it is just a trend in every generationā¦ nothing more than just simple KPI.
PHY layer is already deadā¦it will be almost impossible to get something new out of OFDMA-based signals
The only hope for further network densification as a consequence of (or as a resultš) of using sub-THz bands
Actually, I am going to release my 6G course when I tell about every aspects of future networks including spectrumā¦
Just few weeks!
P.S. there are a lot of insights from industry and academia
