1. A method for controlling transmission power from radio units, the method comprising:
dynamically monitoring channel state feedback for a radiofrequency signal communicated between a first radio unit of the radio units and each of user devices in a transmitted frequency range, wherein the channel state feedback is based at least in part on a metric of quality of the communicated radiofrequency signal;
generating an interference graph representing strength of communications between each of the radio units and each of the user devices with which the radio units are in communication based at least in part on the channel state feedback;
determining that the interference graph satisfies a channel state condition, wherein the channel state condition includes a metric to evaluate performance of the radio units relative to the user devices based at least in part on the metric of quality of the communicated radiofrequency signal; and
transmitting an instruction to adjust a transmission power in the transmitted frequency range of at least one of the radio units based at least in part on the satisfaction of the channel state condition.
