    • Antenna array configurations for massive MIMO outdoor base stations 

      Artiga Campos, Xavier; Perruisseau Carrier, Julien; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Massive MIMO predicts unprecedented capacity and energy efficiency improvements in future networks, by the use of base stations with hundreds of antennas. However the crucial question of determining suitable, or even ...

    • Auction-based offloading for base station switching off in Heterogeneous Networks 

      Bousia, Alexandra; Kartsakli, Elli; Antonopoulos, Angelos; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The emerging traffic demand has triggered an impressive deployment of network infrastructure, including macro Base Stations (BSs) and Small Cells (SCs), leading to increased energy consumption and expenditures. However, ...

    • Average performance analysis of circular and hyperbolic geolocation 

      Urruela Planas, Andreu; Sala Álvarez, José; Riba Sagarra, Jaume (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-01-31)
      Article
      Accés obert
      A comparative performance analysis of four geolocation methods in terms of their theoretical root mean square positioning errors is provided. Comparison is established in two different ways: strict and average. In the ...

    • Evolutionary 4G/5G network architecture assisted efficient handover signaling 

      Jain, Akshay; López Aguilera, M. Elena; Demirkol, Ilker Seyfettin (Institute of Electrical and Electronics Engineers (IEEE), 2018-12-06)
      Article
      Accés obert
      Future wireless networks are expected to be ultra-dense and heterogeneous not just in terms of the number and type of base stations but also in terms of the number of users and the application types they access. Such a ...

    • FBMC-based random access signal design and detection for LEO base stations 

      Caus López, Màrius; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2022-10-04)
      Article
      Accés obert
      The integration of non-terrestrial networks into the 5G ecosystem is mainly driven by the possibility of provisioning service in remote areas. In this context, the advent of flying base stations at the low Earth orbit (LEO) ...

    • Location area planning and cell-to-switch assignment in cellular networks 

      Demirkol, Ilker Seyfettin; Ersoy, Cem; Caglayan, Mehmet; Delic, Hakan (Institute of Electrical and Electronics Engineers (IEEE), 2004-05)
      Article
      Accés restringit per política de l'editorial
      Location area (LA) planning plays an important role in cellular networks because of the tradeoff caused by paging and registration signalling. The upper boundary for the size of an LA is the service area of a mobile services ...

    • Uplink beamforming for the FDD mode of UTRA 

      Mestre Pons, Francesc X.; Rodríguez Fonollosa, Javier; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Text en actes de congrés
      Accés obert
      This paper presents some link level simulation results for the evaluation of adaptive antennas in the uplink of the FDD mode of UTRA (UMTS terrestrial radio access). Two families of algorithms were initially considered, ...
