Reinforcement Learning-based Joint Handover and Beam Tracking in Millimeter-wave Networks
Sara Khosravi, Hossein S. Ghadikolaei, Jens Zander +1
In this paper, we develop an algorithm for joint handover and beam tracking in millimeter-wave (mmWave) networks. The aim is to provide a reliable connection in terms of the achiev…
Simple HF antenna efficiency comparisons using the WSPR system
Jens Zander
Determining the efficiency of an HF-antenna by measurements requires is a complex procedure involving expensive equipment, calibrated instruments for field strengths. In this paper…
Digital Twin Assisted Risk-Aware Sleep Mode Management Using Deep Q-Networks
Meysam Masoudi, Ebrahim Soroush, Jens Zander +1
Base stations (BSs) are the most energy-consuming segment of mobile networks. To reduce BS energy consumption, different components of BSs can sleep when BS is not active. Accordin…
Beam Alignment Using Trajectory Information in Mobile Millimeter-wave Networks
Sara Khosravi, Hossein S. Ghadikolaei, Jens Zander +1
Millimeter-wave and terahertz systems rely on beamforming/combining codebooks to determine the best beam directions during the initial access and data transmission. Existing approa…
Location-Aided Beamforming in Mobile Millimeter-Wave Networks
Sara Khosravi, Hossein S. Ghadikolaeiy, Jens Zander +1
Due to the large bandwidth available, millimeter-Wave (mmWave) bands are considered a viable opportunity to significantly increase the data rate in cellular and wireless networks.…
Beyond the Ultra-Dense Barrier - Paradigm shifts on the road beyond 1000x wireless capacity
Jens Zander
It has become increasingly clear that the current design paradigm for mobile broadband systems is not a scalable and economically feasible way to solve the expected future 'capacit…
