We propose a mechanism that enables the application of frequency sharing technology to communication systems where it has not been previously applicable. [Solution] The information processing device of the present disclosure includes a control unit. The control unit acquires a first frequency range used by a first communication device and first area information relating to the first communication device. The control unit determines, based on the first area information and second area information relating to the second communication device, whether to permit the start or continuation of radio wave transmission by a second communication device whose second frequency range overlaps with the first frequency range.

Embodiments of the present disclosure are directed to systems and methods for avoiding or mitigating co-channel interference between terrestrial and satellite radio access networks (RANs). The systems and methods comprise one or more terrestrial base stations and one or more satellite base stations, each configured to transmit signals across overlapping frequency bands. The system further comprises applying an orthogonal spread spectrum code to the signals transmitted by the satellite base station, while the terrestrial base station transmits without such coding.

The application provides a satellite-terrestrial spectrum sharing method, device and equipment and a readable storage medium, and belongs to the technical field of communication. The satellite-terrestrial spectrum sharing method comprises the following steps: acquiring low-orbit satellite network information and ground cellular network information in a first time slot period, wherein the first time slot period comprises at least one time slot; obtaining a constraint target and a constraint condition of satellite-terrestrial spectrum sharing according to the low-orbit satellite network information and the ground cellular network information; obtaining a service beam in each beam cluster in a plurality of beam clusters in the first time slot period and a service time slot corresponding to the service beam in the first time slot period according to the constraint target and the constraint condition; each beam cluster comprises at least one low-orbit satellite beam, and the service beam is at least one beam in the at least one low-orbit satellite beam. According to the application, the low-orbit satellite network information and the ground cellular network information are considered, a beam hopping pattern is designed, and the application of the beam hopping technology in the satellite-terrestrial frequency sharing scene is realized.
