2. 1. Seamless Millimeter-wave Connectivity via Efficient Beamforming and Handover

   Author : Sara Khosravi; Marina Petrova; Jens Zander; Riku Jäntti; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave networks; Beamforming; Handover; Reinforcement learning; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Extremely high data rate demands, and the spectrum scarcity at the microwave bands, make the millimeter wave (mmWave) band a promising solution to satisfy the high data rate demands in wireless networks. The main advantage of moving to the mmWave spectrum is the availability of large bandwidth. READ MORE

4. 2. Location-aided Beam Alignment and Handover in Millimeter-wave Networks

   Author : Sara Khosravi; Marina Petrova; Jens Zander; Sofie Pollin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave networks; beam alignment; Handover; Reinforcement learning; Millimetervågnätverk; strålinriktning; överlämning; förstärkningsinlärning;

   Abstract : Ever-increasing data rate demands in mobile networks and the spectrum scarcity at the microwave bands have resulted in the exploration of millimeter-wave (mmWave) frequencies for the next generation of wireless networks. While mmWave frequencies offer large bandwidth, communication at these frequencies is not straightforward due to the challenging propagation characteristics. READ MORE

   Abstract : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. READ MORE

6. 4. Inter-System Handovers in Heterogeneous Wireless Systems

   Author : Henrik Persson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hierarchical structure; performance analysis; inter-system handover; wireless systems; handover terminology;

   Abstract : To better utilize existing wireless systems, they can be combined together to interact and thereby provide better balanced capacity. They can further profit from this by getting their ongoing connection moved from the current system to another. The main issues are to make this move without losing the ongoing connection and to make it seamless, i.e. READ MORE
