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

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

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

    Abstract : 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.
