  1. 1. Machine Learning Technique for Beam Management in 5G NR RAN at mmWave Frequencies

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

    Författare :Joel Bill; Gustav Fahlén; [2020]
    Nyckelord :Machine Learning; Reinforcement Learning; Beam Management; Beam Tracking; mmWaves; Technology and Engineering;

    Sammanfattning : Ericsson has an interest in investigating if the fast-growing concept known as machine learning can be applied to beam management, in a 5G NR environment using mmWave frequencies. Because of the high path-loss at mmWave frequencies and high throughput demands of 5G NR systems it is crucial to the UE to always stay connected to the most suitable beam, to provide highest possible throughput.

    Sammanfattning : Around 60 million people around the world are struggling with a traumatic brain or spinal cord injury. The swelling of the brain or spinal cord happen when the water content in the CNS increase due, infection, tumor growth or brain edema. LÄS MER

  3. 3. The Art of Scarcity

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Alexandra Brüchert; Lorenzo Dirksz; Nsunge Kaniki; [2020]
    Nyckelord :Scarcity; Luxury Branding; Fashion Branding; Contemporary Art; Limited Editions; Business and Economics;

    Sammanfattning : The purpose of this paper is to explore the phenomenon of scarcity in branding within the fashion industry. Secondly, the aim is to show how fashion brands can utilize scarcity as a branding tool to transform products into luxury collector’s fashion items. The research shows that there are several connections between the presented cases. LÄS MER

  4. 4. Machine Learning Uplink Power Control in Single Input Multiple Output Cell-free Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yiyang Tai; [2020]
    Nyckelord :Neural networks; Power allocation; Matched-filter reception; Max-min; Max-product; Geometric programming; Neurala nätverk; Strömallokering; Matchad filtermottagning; Max-min; Max-produkt; Geometrisk programmering;

    Sammanfattning : This thesis considers the uplink of cell-free single input multiple output systems, in which the access points employ matched-filter reception. In this setting, our objectiveis to develop a scalable uplink power control scheme that relies only on large-scale channel gain estimates and is robust to changes in the environment. LÄS MER

  5. 5. 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
