Managing interference for coexistence of terrestrial and non-terrestrial wireless networks

A system comprising:

• one or more processors;
• and
• one or more memories storing instructions that, when executed by the one or more processors, cause the system to:
• determine one or more frequency bands assigned to one or more adjacent satellites, the one or more adjacent satellites serving one or more adjacent geographic regions to a reference geographic region served by a reference satellite;
• determine one or more interference characteristics of the one or more frequency bands used by the one or more adjacent satellites;
• determine one or more spectrum blanking ranges for the one or more wireless client devices, the one or more spectrum blanking ranges restricting wireless frequencies in the one or more spectrum blanking ranges from being assigned to the one or more wireless client devices for terrestrial wireless communication;
• select a frequency band for use by the reference satellite in the reference geographic region based on the one or more interference characteristics of the one or more frequency bands assigned to the one or more adjacent satellites, the selected frequency band being selected from a set of available frequency bands for non-terrestrial wireless communication with one or more wireless client devices;
• and
• instruct the reference satellite to use the selected frequency band for communication with the one or more wireless client devices in the reference geographic region.

A computer-implemented method comprising:

• determining one or more frequency bands assigned to one or more adjacent satellites, the one or more adjacent satellites serving one or more adjacent geographic regions to a reference geographic region served by a reference satellite, determining the one or more frequency bands;
• selecting a frequency band for use by the reference satellite in the reference geographic region based on the one or more frequency bands assigned to the one or more adjacent satellites, the selected frequency band being selected from a set of available frequency bands for non-terrestrial wireless communication with one or more wireless client devices;
• instructing the reference satellite to use the selected frequency band for communication with the one or more wireless client devices in the reference geographic region;
• determining a spectrum blanking range for a wireless client device based on the selected frequency band, the spectrum blanking range restricting wireless frequencies in the spectrum blanking range from being assigned to the wireless client device for terrestrial wireless communication;
• and
• assigning a wireless communication channel to the wireless client device by a ground node of a cell in which the wireless client device is located based on a signal quality indicator value and the selected frequency band.
