1. A method to dynamically reassign radio frequency (RF) spectrum from a first access node to a second access node, wherein the first access node provides wireless communication service on a first carrier having a carrier bandwidth, the method comprising:
determining a width of frequency to reassign from the first access node to the second access node, wherein the carrier bandwidth defines a plurality of physical resource blocks (PRBs), and wherein the determining the width of frequency comprises determining a quantity of PRBs;
selecting a frequency portion of the carrier bandwidth and of the determined width to reassign from the first access node to the second access node, wherein the selecting is based on determined noise on the frequency portion compared with determined noise respectively on each of one or more other frequency portions of the carrier bandwidth, wherein selecting the frequency portion based on the determined noise on the frequency portion compared with the determined noise respectively on each of the one or more other frequency portions of the carrier bandwidth is based on at least one of uplink noise or downlink noise; and
based on the selecting, reassigning the selected frequency portion from the first access node to the second access node to be used by the second access node as at least part of a second carrier on which to provide wireless communication service,
whereby, upon the reassigning of the selected frequency portion, the first access node then continues to provide wireless communication service on a remainder of the first carrier.
