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 resultšŸ˜) 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 :face_with_monocle:

As of June 2026, 3GPP has locked in the baseline: CP-OFDM for downlink, CP-OFDM + DFT-s-OFDM for uplink. So itā€™s still OFDM-based, not a clean-break waveform. Release 21 (the first official 6G specs) runs March 2027ā€“end 2028, commercial rollout expected ~2030. Main debate now is backward compatibility with 5G-Advanced, plus heavy focus on AI-native design, RIS, and sub-THz/upper-mid-band spectrum.
