Not necessarily for 4G to 5G. 5G can run a 4G compatible control channel and timeslices can be 4G or 5G.

Maybe, but at least in the US, 4G wad deployable on new lower frequency spectrum that had previously been used for TV. LTE 71, 600 Mhz is lower frequency but wouldn't have been usable for 3G because legacy phones didn't use those frequencies.
that's why I said "kept on the lower G". If a new lower one pops up, that's a different story.
