Satellite communication system and method for managing radio resource of non-terrestrial network

A method for managing radio resources of a non-terrestrial network, adaptable for a satellite communication system, wherein the satellite communication system comprises a first satellite and a second satellite, and the method comprises:

• transmitting a first resource scheduling assignment by the first satellite when leaving a service area of the non-terrestrial network;
• receiving a second resource scheduling assignment corresponding to the first resource scheduling assignment when the second satellite enters the service area;
• and
• accessing the radio resources by the second satellite according to the second resource scheduling assignment.

A satellite for managing radio resources of a non-terrestrial network, comprising:

• a transceiver;
• and
• a processor, coupled to the transceiver, wherein the processor is configured to:
• receive a first resource scheduling assignment from a second satellite through the transceiver in response to entering a service area of the non-terrestrial network;
• and
• access the radio resources through the transceiver according to the first resource scheduling assignment.

A ground station for managing radio resources of a non-terrestrial network, comprising:

• a transceiver;
• and
• a processor, coupled to the transceiver, wherein the processor is configured to:
• receive, through the transceiver, a first resource scheduling assignment from a first satellite which leaves a service area of the non-terrestrial network;
• and
• transmit, through the transceiver, a second resource scheduling assignment to a second satellite which enters the service area according to the first resource scheduling assignment.
