  • Bonfante, Andrea; Galati Giordano, Lorenzo; López Pérez, David; García Rodríguez, Adrián; Geraci, Giovanni; Baracca, Paolo; Butt, Majid; Marchetti, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    In this paper, we focus on one of the key technologies for the fifth-generation wireless communication networks, massive multiple-input-multiple-output (mMIMO), by investigating two of its most relevant architectures: ...
  • D’Andrea, Carmen; García Rodríguez, Adrián; Geraci, Giovanni; Galati Giordano, Lorenzo; Buzzi, Stefano (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We study support for unmanned aerial vehicle (UAV) communications through a cell-freemassive MIMO architecture, wherein a large number of access points (APs) is deployed in place of largeco-located massive MIMO arrays. We ...
  • D’Andrea, Carmen; García Rodríguez, Adrián; Geraci, Giovanni; Galati Giordano, Lorenzo; Buzzi, Stefano (Institute of Electrical and Electronics Engineers, 2019)
    We study support for unmanned aerial vehicle (UAV) communications through a cell-free massive MIMO ar- chitecture. Under the general assumption that the propagation channel between the mobile stations, either UAVs or ground ...
  • Azari, M. Mahdi; Geraci, Giovanni; García Rodríguez, Adrián; Pollin, Sofie (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Reliable and direct communication between un-manned aerial vehicles (UAVs) could facilitate autonomous flight, collision avoidance, and cooperation in UAV swarms. In this paper, we consider UAV-to-UAV (U2U) communica-tions ...
  • García Rodríguez, Adrián; Geraci, Giovanni; López Pérez, David; Galati Giordano, Lorenzo; Ding, Ming; Björnson, Emil (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    What will it take for drones—and the whole associated ecosystem—to take off? Arguably, infallible command and control (C&C) channels for safe and autonomous flying, and high-throughput links for multi-purpose live video ...
  • Liu, Fan; García Rodríguez, Adrián; Masouros, Christos; Geraci, Giovanni (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    In this paper, we focus on the coexistence between a MIMO radar and cellular base stations. We study the interfering channel estimation, where the radar is operated in the “search and track” mode, and the BS receives the ...
  • García Rodríguez, Adrián; Geraci, Giovanni; Galati Giordano, Lorenzo; Bonfante, Andrea; Ding, Ming; López Pérez, David (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Nowadays, the demand for wireless mobile services is copious, and will continue increasing in the near future. Mobile cellular operators are therefore looking at the unlicensed spectrum as an economical supplement to ...
  • Azari, M. Mahdi; Geraci, Giovanni; García Rodríguez, Adrián; Pollin, Sofie (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We consider a cellular network deployment where UAV-to-UAV (U2U) transmit-receive pairs share the same spectrum with the uplink (UL) of cellular ground users (GUEs). For this setup, we focus on analyzing and comparing ...
  • Geraci, Giovanni; García Rodríguez, Adrián; Galati Giordano, Lorenzo; López Pérez, David; Björnson, Emil (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis ...
