4. 3. 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.

5. 4. Simulation-Based Stochastic Blockage Model for Millimeter-wave Communication

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

   Författare :Mihret Getye Sidelel; [2020]
   Nyckelord :;

   Sammanfattning : Recently, the growing demand for high data rates in wireless communication, together with the scarcity of spectrum in existing microwave bands, has motivated the use of millimeter-wave (mmWave) bands for 5G and future wireless communications. Even though mmWaves are potential candidates for fulfilling this rising demand, they come along with their own drawbacks that need to be addressed. LÄS MER
