1. 21. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Qinglong He; [2022]
   Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

   Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE

3. 22. Simulation of Radio Propagation Path in Indoor Environment

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Minu Revathikumar; [2022]
   Keywords : Indoor 3D propagation model; millimeter waves mmWaves ; 5G; Basic propagation mechanism; Excess loss; Inomhus 3Dspridnings modell; millimeter vågor mmVågor ; 5G; Grundläggande spridnings mekanism; Överskotts förlust;

   Abstract : Several propagation channel models are designed to verify signal behavior in specific environments for future 5G cellular networks. Hence, with the massive development and demand of indoor wireless systems, a suitable design prior to deployment is required for energy and cost-efficient implementations. READ MORE

4. 23. Recommendation Engine via Flexible Latent Explorations : Adaptation of Variational Autoencoders for Telecom domain

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Aliaksandr Samson; [2022]
   Keywords : ;

   Abstract : While consumers get a lot of benefits with new generations of cellular networks, there is an increasing demand of reducing the energy consumption of telecom nodes. Finding optimal telecom node configurations usually results in network performance degradation. READ MORE

5. 24. Design and Implementation of Cellular Network Hotspot Forecast Using Graph Convolutional Neural Networks

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Adrià Correas I Grifoll; [2022]
   Keywords : ;

   Abstract : This project proposes a type of (Recurrent) Graph Neural Network (RGNN) to predict future hotspots in cellular network data. Current state-of-the-art algorithms process each antenna (celldata )’s in isolation, ignoring the performance of nearby cells and cell locations. READ MORE

6. 25. Initial access in 5G mmWave networks with different base station parameters

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Xiao Yang; [2022]
   Keywords : Initial Access; Millimeter-Wave Network; Cell Search; Random Search; Genetic Algorithm; Machine Learning; Första åtkomst; Millimetervågsnätverk; Cell sökning; Slumpmässig sökning; Genetisk algoritm; Maskininlärning;

   Abstract : Nowadays in the fifth generation (5G) communication systems, millimeter wave (mmWave) has aroused interest to not only industrial use but also network operators due to the massive amount of bandwidth available at mmWave frequencies. Initial access in cellular systems is an essential procedure in which new mobile user equipment (UE) establishes a connection with a base station (BS). READ MORE
