Gabriel Brown of Heavy Reading, a respected analyst, writes "Some of your 6G stuff (e.g. no-cell RAN, above 40GHz, shared spectrum, etc.) was supposed to be 5G. Whether that happens in practice, I’ll guess we’ll see in time. How and when the 5G to 6G threshold is crossed will be interesting." He's right, of course: None of what I'm calling "6G" is news to the best engineers in the industry, including many at 3GPP creating the 5G standard. It's always a tough call as to what is ready; there are also practical limits on complexity. Currently, 3GPP is using spectrum up to 54 GHz, although 60-77 GHz are actively being discussed. Sharing of unlicensed spectrum is central to Rel. 15; but there's an even bigger payoff in sharing some of the current monopoly spectrum.
