Study on beam hopping and frequency reuse in LEO satellite communication

Abstract： Facing wide-area and non-uniformly distributed service requirements, this paper proposes a beam resource management scheme based on improved particle swarm optimization, which considers the joint optimization of beam hopping pattern design, beam frequency allocation and power allocation, in the scenario of multiple LEO satellites with moving beam cells. By system-level simulation, its performance is verified. Specifically, compared with beam resource management schemes based on spatial isolation angle and priority, results show that this proposal can significantly improve user SINR and system capacity under full-buffer service model, and lower frequency reuse factor results in higher system capacity.
