There's 150 MHz of spectrum at 3.55 to 3.7 GHz that's more than half license by rule if one cares enough to use Part 96 compliant equipment, only real downside to it is the EIRP limit is 50 WAnd IS-95 CDMA, and WCDMA, and Wi-Fi, and Bluetooth.
What you'd do is license the spectrum based on power. Within this footprint and this channel, you can contribute x dBm out of a noise floor limit of y dBm. Spectrum efficiency is increased because if you aren't talking, you aren't transmitting and adding to the noise floor, and you can license more users, instead of reserving some number of fixed channels forever.
That's how we regulate Wi-Fi today. At 5 GHz, you're allowed 17 dBm max in any 1 MHz bandwidth.
I hold a 10 MHz channel in the licensed segment of the band in Union County, IN, it's actually a pretty cool concept
The spectrum access system in this band is basically an automated frequency coordinator
