Multibeam high throughput satellite (MB-HTS) systems will play a key role in\ndelivering broadband services to a large number of users with diverse Quality\nof Service (QoS) requirements. This paper focuses on MB-HTS where the same\nspectrum is re-used by all user links and, in particular, we propose a novel\nuser scheduling design capable to provide guarantees in terms of individual QoS\nrequirements while maximizing the system throughput. This is achieved by\nprecoding to mitigate mutual interference. The combinatorial optimization\nstructure requires an extremely high cost to obtain the global optimum even\nwith a reduced number of users. We, therefore, propose a heuristic algorithm\nyielding a good local solution and tolerable computational complexity,\napplicable for large-scale networks. Numerical results demonstrate the\neffectiveness of our proposed algorithm on scheduling many users with better\nsum throughput than the other benchmarks. Besides, the QoS requirements for all\nscheduled users are guaranteed.\n
