Solution Overview

Problem

Conventional satellite base station spectrum allocation methods lack flexibility and fail to efficiently utilize available spectrum due to static approaches, leading to underutilization or congestion, particularly in areas with fluctuating terrestrial network usage.

Innovation Solution

Implementing dynamic spectrum management by satellite base stations that monitor terrestrial PRB allocations in real-time and adjust satellite PRB allocations to minimize interference, using high-sensitivity receivers to detect terrestrial network frequencies and allocate PRBs from opposite ends of the spectrum based on interference patterns.

AI summary

Embodiments of the present disclosure describe systems and methods for dynamic spectrum management and interference mitigation in mobile communications through a network of satellite base stations. Embodiments herein monitor communication traffic across a geographic area served by one or more satellite base stations. The monitoring of the traffic includes determining spectrum assignments for the terrestrial network within the geographic area. In response, the system dynamically adjusts a spectrum assignment to the one or more satellite base stations so the assigned spectrum reduces cross spectrum interference.
