Claims9
A method for determining satellite frequency bands, comprising:
- determining at least one first frequency band available for a land communication system in a current region;
- and
- determining at least one second frequency band available for a satellite communication system in the current region, based on the at least one first frequency band;
- wherein the method is performed by a satellite, and determining the at least one first frequency band available for the land communication system in the current region comprises:
- determining the at least one first frequency band available for the land communication system in the current region, based on the available frequency bands of the land communication system in each region;
- and
- sending a first notification message to a ground station on a first preset frequency band resource, wherein the first preset frequency band resource is a frequency band resource available for the satellite to send the first notification message in the current region as agreed in a protocol, and the first notification message is used to indicate at least one second frequency band available for the satellite in the current region.

A method for determining satellite frequency bands, comprising:
- performing interference detection on at least one first frequency band available for a land communication system in a current region, to obtain an interference detection result;
- and
- determining at least one second frequency band available for a satellite communication system in the current region from the at least one first frequency band based on the interference detection result;
- wherein the method is performed by a ground station or a terminal, and
- in response to the method being performed by a ground station, the method further comprises:
- determining that a satellite arrives in the current region, and sending a third notification message to the satellite on a third preset frequency band resource, wherein the third preset frequency band resource is a frequency band resource available for the ground station to send the third notification message as agreed in a protocol, and the third notification message is used to indicate the at least one second frequency band determined by the ground station for the satellite.

A method for adjusting frequency bands, performed by a satellite, comprising:
- adjusting spectrum resources available when the satellite is in a current region, based on at least one second frequency band available for a satellite communication system in the current region;
- wherein the at least one second frequency band is determined by the satellite, or, the at least one second frequency band is indicated by a frequency band notification message received by the satellite;
- in response to the at least one second frequency band being indicated by the frequency band notification message received by the satellite, adjusting the spectrum resources available for the satellite comprises:
- determining that a base station is installed on the satellite, and adjusting the spectrum resources available when the satellite is in the current region based on the at least one second frequency band indicated by the frequency band notification message;
- or,
- determining that the base station is installed on the ground, and adjusting the spectrum resources available when the satellite is in the current region based on the second frequency band indicated by the frequency band notification message and indication of the base station.
