Abstract:

In order to meet the flexible resource scheduling requirements of the low Earth orbit satellite beam hopping system, a multidimensional resource optimization algorithm for collaborative scheduling of beams and users is proposed. In order to meet differentiated user service needs, this algorithm is based on the “beam hopping+5G non ground network (NTN)” system, utilizing multi-dimensional resource scheduling of time, frequency, space, and energy. It collaboratively optimizes large-scale spatiotemporal resource allocation between beams for multiple targets, and performs fine-grained resource scheduling within beams for user quality of service (QoS). Multi-objective index distribution optimizers and dynamic user priority functions are separately constructed for optimization and solution. The simulation results show that compared with traditional algorithms, this algorithm can effectively meet the differentiated QoS requirements of users for different services in terms of latency and throughput. At the same time, corresponding simulation verification software is designed, which has the advantages of visualization and scalability, and can verify key resource scheduling techniques, display resource utilization, and system performance in real time.
