  • Analytical Characterization of ITLinQ: Channel Allocation for Device-to-Device Communication Networks
    Mungara, Ratheesh K.; Zhang, Xinchen; Lozano Solsona, Angel; Heath, Robert W. (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Device-to-device (D2D) communication allows serving local wireless traffic bypassing the system’s/ninfrastructure. One way to control the interference in D2D networks is to carefully channelize/ntransmissions. This paper ...
  • Is the PHY layer dead?
    Dohler, Mischa; Heath, R. W., Jr.; Lozano Solsona, Angel; Papadias, Constantinos B.; Valenzuela, R. A. (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    This article originates from a panel with the above title, held at IEEE VTC Spring 2009, in which the authors took part. The enthusiastic response it received prompted us to discuss for a wider audience whether research ...
  • Lightweight UAV-based measurement system for air-to-ground channels at 28 GHz
    Semkin, Vasilii; Kang, Seongjoon; Haarla, Jaakko; Xia, William; Huhtinen, Ismo; Geraci, Giovanni; Lozano Solsona, Angel; Loianno, Giuseppe; Mezzavilla, Marco; Rangan, Sundeep (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Wireless communication at millimeter wave frequencies is an attractive option for high-bit-rate connectivity to unmanned aerial vehicles (UAVs). However, conducting the channel measurements necessary to assess the communication ...
  • Line-of-sight MIMO via reflection from a smooth surface
    Lozano Solsona, Angel; Pizzo, Andrea; Rangan, Sundeep; Marzetta, Thomas (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    We provide a deterministic channel model for a scenario where wireless connectivity is established through a reflection from a planar smooth surface of an infinite extent. The developed model is rigorously built upon the ...
  • Massive MIMO unlicensed: a new approach to dynamic spectrum access
    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 ...
  • Multiple ARQ processes for MIMO systems
    Zheng, Haitao; Lozano Solsona, Angel; Haleem, Mohamed (Hindawi, 2004)
    We propose a new automatic repeat request (ARQ) scheme for MIMO systems with multiple transmit and receive antennas. The substreams emitted from various transmit antennas encounter distinct propagation channels and thus ...
  • On the performance of the spatial reuse operation in IEEE 802.11ax WLANs
    Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    The Spatial Reuse (SR) operation included in the IEEE 802.11ax-2020 (11ax) amendment aims at increasing the number of parallel transmissions in an Overlapping Basic Service Set (OBSS). However, many unknowns exist about ...
  • Terahertz line-of-sight MIMO communication: theory and practical challenges
    Do, Heedong; Cho, Sungmin; Park, Jeonghun; Song, Ho-Jin; Lee, Namyoon; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    A relentless trend in wireless communications is the hunger for bandwidth, and fresh bandwidth is only to be found at ever higher frequencies. While 5G systems are seizing the mmWave band, the attention of researchers is ...
  • The Internet of Sounds: convergent trends, insights and future directions
    Turchet, Luca; Lagrange, Mathieu; Rottondi, Cristina; Fazekas, George; Peters, Nils; Østergaard, Jan; Font, Frederic; Backström, Tom; Fischione, Carlo (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Current sound-based practices and systems developed in both academia and industry point to convergent research trends that bring together the field of Sound and Music Computing with that of the Internet of Things. This ...
  • UAV-assisted attack prevention, detection, and recovery of 5G networks
    Sabri Abdalla, Aly; Powell, Keith; Geraci, Giovanni; Marojevic, Vuk (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Unmanned aerial vehicles (UAVs) are emerging as enablers for supporting many applications and services, such as precision agriculture, search and rescue, temporary network deployment or coverage extension, and security. ...
