  4. 3. Lean Beam Management for New Radio

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nawanit Kumar; [2020]
    Nyckelord :5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Sammanfattning : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. LÄS MER

  5. 4. Beamforming in 5G mm-wave radionetworks : Importance of frequency multiplexing for users in urban macro environments

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Carl Lutnaes; [2020]
    Nyckelord :;

    Sammanfattning : 5G brings a few key technological improvements compared to previous generations in telecommunications. These include, but are not limited to, greater speeds, increased capacity and lower latency. These improvements are in part due to using high band frequencies, where increased capacity is found.

  7. 5. Differential Millimetre Wave On-Chip Inductors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Francisco Gonzalez Manero; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The increasingly interconnected world requires systems that support high data rates, and thus the development of mm-wave systems is necessary. Automotive collision radar (80 GHz) or WLANs (60 GHz) are one of the applications that led the increment of the demand in RFICs, in which monolithic devices are fundamental, such as on-chip inductors or transformers.
