      Article
      Accés obert
      This paper elaborates on the design challenges, opportunities, and solutions for New Radio-based access to Unlicensed spectrum (NR-U) by taking into account the beam-based transmissions and the worldwide regulatory ...

    • Novel radio environment map for the ns-3 NR simulator 

      Koutlia, Katerina; Bojovic, Biljana; Lagén Morancho, Sandra; Giupponi, Lorenza (Association for Computing Machinery (ACM), 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Radio Environmental Map (REM) is a useful tool to visualize the network coverage, including signal quality and interference, in multi-cell scenarios. Although REM maps for omnidirectional transmissions/receptions and tools ...

    • NR-U and IEEE 802.11 technologies coexistence in unlicensed mmWave spectrum: models and evaluation 

      Patriciello, Natale; Lagén, Sandra; Bojovic, Biljana; Giupponi, Lorenza (Institute of Electrical and Electronics Engineers (IEEE), 2020-04-13)
      Article
      Accés obert
      New Radio-based access to Unlicensed spectrum (NR-U) intends to expand the applicability of 5G NR access technology to support operation in unlicensed bands by adhering to Listen-Before-Talk (LBT) requirement for accessing ...

    • On the potential of ensemble regression techniques for future mobile network planning 

      Moysen Cortes, Jessica; Giupponi, Lorenza; Mangues Bafalluy, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Planning of current and future mobile networks is becoming increasingly complex due to the heterogeneity of deployments, which feature not only macrocells, but also an underlying layer of small cells whose deployment is ...

    • Predicting QoS in LTE HetNets based on location-independent UE measurements 

      Moysen Cortes, Jessica; Giupponi, Lorenza; Baldo, Nicola; Mangues Bafalluy, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper aims to find patterns of knowledge from physical layer data coming from Heterogeneous Long Term Evolution (LTE) networks. We discuss how the collected data is employed in such a manner that improves Minimization ...

    • Realistic beamforming design using SRS-based channel estimate for ns-3 5G-LENA module

      Text en actes de congrés
      Accés restringit per política de l'editorial
      Beamforming (BF) is a key procedure to overcome propagation limits in millimeter-wave bands but also to extend network coverage in sub 6 GHz bands, as considered in recent 3GPP and IEEE communication standards. Up to date, ...

    • Self coordination among SON functions in LTE heterogeneous networks 

      Moysen Cortes, Jessica; Giupponi, Lorenza (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In a self-organized Long Term Evolution (LTE) network, different Self-Organizing Network (SON) functions or different instances of the same SON function can execute parallel actions, which interact or collide among each ...

    • Self-coordination of parameter conflicts in D-SON architectures: a Markov decision process framework 

      Moysen Cortes, Jessica; Giupponi, Lorenza (2015-12-01)
      Article
      Accés obert
      We consider a distributed SON (D-SON) architecture where the interaction of different self-organizing network (SON) functions negatively affect the performances of the system. This is referred to in 3rd Generation Partnership ...
