Dynamically Reassigning a High-Noise Frequency Segment from a First Access Node to a Second Access Node

A first access node comprising:

• a wireless communication interface supporting air-interface communication on a first carrier, wherein the first carrier has a carrier bandwidth;
• a backhaul communication interface;
• and
• a controller configured to carry out operations to dynamically reassign radio frequency (RF) spectrum from the first access node to a second access node, wherein the controller comprises at least one processor, non-transitory data storage, and program instructions stored in the non-transitory data storage and executable by the at least one processor to carry out the operations, and wherein the operations include:
• selecting a frequency portion of the carrier bandwidth 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.

A computing system configured 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 computing system comprising:

• at least one processor;
• at least one non-transitory data storage;
• and
• program instructions stored in the at least one non-transitory data storage and executable by the at least one processor to carry out operations including (i) selecting a frequency portion of the carrier bandwidth 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 (ii) 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.
