A method and apparatus for measuring and reporting cross-link interference are provided. The method includes receiving, from a base station (BS), a measurement configuration for the CLI, performing measurement on the configured measurement object based on the measurement configuration for the CLI and transmitting, to the BS, based on a measurement result of at least one of a resource from a plurality of resources for measuring the CLI of the configured measurement object exceeding a threshold, a measurement report for all of the plurality of resources for measuring the CLI of the configured measurement object whose measurement result exceeds the threshold.

A device and method for managing communication frequencies, including generating a geographical grid with a plurality of cells and allocating communication frequencies to the cells. Each of the communication frequencies is used for communication between a satellite and a ground device or ground IoT modem. A communication frequency allocated to one cell is different from the communication frequencies allocated to each of the immediately surrounding cells. A set of communication frequencies is selected for communication between the satellite and ground devices based on a ground track of the satellite. The selected set is transmitted to the satellite to communicate with the ground station located in a cell with the communication frequency allocated to that cell.
