    • Adaptive beam pattern selection and resource allocation for NOMA-based LEO satellite systems 

      Wang, Anyue; Lei, Lei; Hu, Xin; Lagunas Targarona, Eva; Pérez Neira, Ana Isabel; Chatzinotas, Symeon (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report
      Open Access
      The low earth orbit (LEO) satellite system is one of the promising solutions to provide broadband services to a wide-coverage area for future integrated LEO-6G networks, where users' demands vary with time and geographical ...
    • Joint beam-hopping scheduling and power allocation in NOMA-assisted satellite systems 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Chatzinotas, Simeon; Pérez Neira, Ana Isabel; Ottersten, Bjorn (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      In this paper, we investigate potential synergies of non-orthogonal multiple access (NOMA) and beam hopping (BH) for multi-beam satellite systems. The coexistence of BH and NOMA provides time-power-domain flexibilities in ...
    • Joint optimization of beam-hopping design and NOMA-assisted transmission for flexible satellite systems 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Pérez Neira, Ana Isabel; Chatzinotas, Symeon; Ottersten, Björn (Institute of Electrical and Electronics Engineers (IEEE), 2022-10)
      Article
      Open Access
      Next-generation satellite systems require more flexibility in resource management such that available radio resources can be dynamically allocated to meet time-varying and non-uniform traffic demands. Considering potential ...
    • NOMA-enabled multi-beam satellite systems: Joint optimization to overcome offered-requested data mismatches 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Pérez Neira, Ana Isabel; Chatzinotas, Symeon; Ottersten, Björn (Institute of Electrical and Electronics Engineers (IEEE), 2021-01)
      Article
      Open Access
      Non-Orthogonal Multiple Access (NOMA) has the potentials to improve the performance of multi-beam satellite systems. The performance optimization in satellite-NOMA systems can be different from that in terrestrial-NOMA ...
    • On fairness optimization for NOMA-enabled multi-beam satellite systems 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Pérez Neira, Ana Isabel; Chatzinotas, Simeon; Ottersten, Bjorn (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      In a multi-beam satellite communication system, traffic requests are typically asymmetric across beams and highly heterogeneous among terminals. In practical operations, it is important to achieve a good match between the ...
