    Article
    Accés obert
    OAPA The definition of the next generation of wireless communications, so-called 5G networks, is currently underway. Among many technical decisions, one that is particularly fundamental is the choice of the physical layer ...
  • Energy-and spectrum-efficient user association in millimeter-wave backhaul small-cell networks 

    Mesodiakaki, Agapi; Adelantado Freixer, Ferran; Alonso Zárate, Luis Gonzaga; di Renzo, Marco; Verikoukis, Christos (2017-02-01)
    Article
    Accés obert
    Macrocells are expected to be densely overlaid by small cells (SCs) to meet increasing capacity demands. Due to their dense deployment, some SCs will not be connected directly to the core network, and thus, they may forward ...
