Mitigation of interference between terrestrial networks (TN) and non-terrestrial networks (NTN) in integrated communication systems may be achieved by reducing the interference at both networks such that co-channel inter-system interference may be minimized and spectral efficiency may be improved. Additionally, by improving spectrum sharing between TN and NTN, higher throughput may be achieved and user coverage may be expanded. By integrating a directional interference adjustment factor (DIAF) into a power control mechanism, a system can make more informed and precise adjustments to its transmit power. By considering the DIAF, the system may dynamically adjust power to, thereby, minimize interference with other networks or users. Minimization of interference is especially convenient in environments where multiple networks share the same spectrum. Adjusting power based on the DIAF helps maintain a better signal to interference and noise ratio, leading to more reliable communication and better data rates.
