Resource Allocation for Beam-hopping User Downlinks in Multi-beam Satellite System

Abstract

Traditional fixed resource allocation lacks sufficient flexibility, considering the diversity service requirements of multi-beam satellite systems, this paper proposes a flexible resource allocation mechanism based on "beam-hopping" technology. Firstly, a scheme of uniform clustering is proposed, and the objective function is established to find the optimal cluster size. Secondly, to achieve efficient utilization of resources, the power and time slot combination optimization algorithms are proposed to realize the on-demand allocation. Simulation results show that the proposed method makes the allocated capacity meet the dynamic demand better than traditional methods.
