1. 6. Coverage Prediction for Inter-Frequency Handover using Machine Learning with Aggregated Training Data

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

   Författare :Torsten Molitor; [2020]
   Nyckelord :;

   Sammanfattning : An important application of Machine Learning (ML) in mobile networks is to predict if a user device has coverage on a frequency other than the current serving frequency. This is a use-case called Secondary Carrier Prediction (SCP). LÄS MER

3. 7. Visualizing Carrier Aggregation Combinations

   Master-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Fredrik Helders; [2019]
   Nyckelord :LTE; Carrier Aggregation; Visualization; Graph traversal; Load balancing; 4G; 3GPP;

   Sammanfattning : As wireless communications is becoming an increasingly important part of ourevery day lives, the amount of transmitted data is constantly growing, creating ademand for ever-increasing data rates. One of the technologies used for boostingdata rates is carrier aggregation, which allows for wireless units to combine multipleconnections to the cellular network. LÄS MER

4. 8. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

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

   Författare :Tomás Soares da Costa; [2019]
   Nyckelord :;

   Sammanfattning : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. LÄS MER

5. 9. Predicting inter-frequency measurements in an LTE network using supervised machine learning : a comparative study of learning algorithms and data processing techniques

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Adrian Sonnert; [2018]
   Nyckelord :Telecommunications; Telecom; Mobile networks; 4G; LTE; LTE-A; Machine learning; Random forest; Gradient boosting; Neural network; Multi-layer perceptron; Logistic regression; Frequency measurements; Handover; Load balancing; Carrier aggregation;

   Sammanfattning : With increasing demands on network reliability and speed, network suppliers need to effectivize their communications algorithms. Frequency measurements are a core part of mobile network communications, increasing their effectiveness would increase the effectiveness of many network processes such as handovers, load balancing, and carrier aggregation.
