  1. 1. Adaptive Frequency Resolution for Downlink Beamforming in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Johanna Bengtsson; [2021]
    Keywords : beamforming; MIMO; 5G; 5G NR; Technology and Engineering;

    Abstract : As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. READ MORE

  3. 2. Performance evaluation of direct air-to-ground communication using new radio (5G)

    University essay from KTH/Teknisk informationsvetenskap

    Author : Liheng Liu; [2017]
    Keywords : direct air-to-ground communication DA2GC ; 5G; new radio; mobile broadband; beamforming; Direkt luft till markkommunikation DA2GC ; 5G; ny radio; mobilt bredband; lobformning;

    Abstract : Providing mobile broadband (MBB) coverage to passengers in planes (and other yingobjects) has been one of the very important requirements by airline industry for sometime. With the emergence of high-capacity wireless network concepts, there is a renewedeort in dening systems based on 5G (also dened as NR, new radio) for air-to-ground(A2G) communication. READ MORE

  4. 3. Performance of In-Band Full-Duplex for 5G Wireless Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Osama Al-Saadeh; [2016]
    Keywords : Wireless networks; In-band full duplex; Static-time division duplexing; Dynamic-time division duplexing; Interference mitigation techniques; small cell; 5G; mmWave bands; Beamforming; Interference cancellation.; Trådlösa nätverk; Inomband hel duplex; Statisk tidsdelning; Dynamisk tidsdelning; Störningsundertryckningsmetoder; Små celler; 5G; Millimetervågsfrekvenser; Lobformning; Störningseliminering.;

    Abstract : In-band full duplex is a new duplexing scheme that allows radio nodes to transmit and receive, utilizing the same frequency and time resources. The implementation of in-band full duplex was not feasible in practice, due to the effect of self-interference. But then, advances in signal processing made it possible to reduce this effect.

  5. 4. Beam-Forming-Aware Link-Adaptation for Differential Beam-Forming in an LTE FDD System

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Mikael Karlsson; [2016]
    Keywords : Beam-Forming-Aware; Link-Adaptation; Differential Beam-Forming; LTE;

    Abstract : The ability for base stations to be able to beam-form their signals, directing the signal energy to specific users, is a topic of research that has been heavily studied during the last decades. The beam-forming technique aims to increase the signal-to-interference-and-noise-ratio of the user and, consequently, increase the capacity and coverage of the communication system. READ MORE

  6. 5. Differential Beam-Forming Using Two-Dimensional Antenna Arrays in an LTE FDD System

    University essay from Linköpings universitet/KommunikationssystemLinköpings universitet/Tekniska fakulteten

    Author : Fredrik Stenmark; [2015]
    Keywords : Antenna Array; Beam Focusing; Beam-Forming; Feedback Process; Long Term Evolution; Precoding;

    Abstract : Basstationer med flera antenner kan aktivt styra signalenergi mot en mottagare med hjälp av lobformning, vilket ger högre datatakt och lägre strömförbrukning än med en enda antenn. Lobformning kräver dock att kanalen skattas till varje antenn och i ett FDD-system måste denna skattning återkopplas till basstationen från mottagaren, vilket innebär en opraktiskt stor overhead, speciellt när loberna blir smalare.
