Systems, devices, and methods for scheduling spectrum for spectrum sharing

A method comprising:

• receiving, at a base station of a radio-frequency communication network, a signal from a user equipment;
• and
• scheduling spectrum for the user equipment based at least in part on:
• a signal-to-interference-and-noise ratio of the signal,
• a transmission-power constraint of the base station, and
• information regarding past usage of the spectrum.

A system comprising:

• a computer-readable medium comprising computer executable instructions that, when executed via a processing unit of a computing system, cause the computing system to perform
• operations, the operations comprising:
• receiving a signal received at a base station of a radio-frequency communication network from a user equipment, and
• scheduling spectrum for the user equipment based at least in part on:
• a signal-to-interference-and-noise ratio of the signal,
• a transmission-power constraint of the base station, and
• information regarding past usage of the spectrum.
