1. 1. Multi-Gigabit Radio System Demonstrators for Next Generation Mobile Networks

   Författare :Jingjing Chen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fronthaul; E-band; modem; millimeter-wave transmission; mobile backhaul; multi-gigabit; differential coding; phase noise mitigation; FPGA; 16-QAM; DQPSK; point-to-point radio; centralized baseband;

   Sammanfattning : Driven by the exponential growth in mobile broadband subscriptions and mobile data traffic, transport capacity of mobile networks has to be enhanced accordingly, including wireless backhaul and the emerging fronthaul networks. Utilizing wide bandwidth is the most straightforward way to capacity upgrade. LÄS MER

3. 2. Agile, Resilient and Cost-efficient Mobile Backhaul Networks

   Författare :Forough Yaghoubi; Lena Wosinska; Marija Furdek; Jiajia Chen; Amitava Mukherjee; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; software defined networking; rain disturbance; technoeconomic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Although, heterogeneous networks (HetNets) are a promising solution for the wireless access, the backhaul segment has received considerably less attention and falls short in meeting the stringent requirements of 5G in terms of capacity and availability.

4. 3. Agile, Resilient and Cost-efficient Mobile Backhaul Networks : Fundamentals of Network Design and Adaptation

   Författare :Forough Yaghoubi; Marija Furdek; Lena Wosinska; Dipak Ghosal; KTH; []
   Nyckelord :5G; topology design and control; software defined networking; rain disturbance; techno-economic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Whilst substantial research efforts address the access segment, the backhaul part has received less attention and still falls short in meeting the stringent requirements of 5G in terms of capacity and availability.

5. 4. Predictor Antenna Systems: Exploiting Channel State Information for Vehicle Communications

   Författare :Hao Guo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; Beyond 5G; temporal correlation; spatial correlation; wireless backhaul; outage probability; hybrid automatic repeat request HARQ ; channel state information CSI ; throughput; integrated access and backhaul IAB ; mobile relay; predictor antenna PA ; mobility; Marcum Q-function; relay; rate adaptation;

   Sammanfattning : Vehicle communication is one of the most important use cases in the fifth generation of wireless networks (5G).  The growing demand for quality of service (QoS) characterized by performance metrics, such as spectrum efficiency, peak data rate, and outage probability, is mainly limited by inaccurate prediction/estimation of channel state information (CSI) of the rapidly changing environment around moving vehicles.

7. 5. Towards Context Information-based High-Performing Connectivity in Internet of Vehicle Communications

   Författare :Hao Guo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporal correlation; relay; Internet-of-vehicles IoV ; reconfigurable intelligent surface; throughput; wireless backhaul; outage probability; channel state information CSI ; 5G B5G; spatial correlation; rate adaptation; mobile relay; 6G; vehicle-to-everything V2X ; Marcum Q-function; integrated access and backhaul IAB ; predictor antenna; blockage; millimeter wave;

   Sammanfattning : Internet-of-vehicles (IoV) is one of the most important use cases in the fifth generation (5G) of wireless networks and beyond. Here, IoV communications refer to two types of scenarios: serving the in-vehicle users with moving relays (MRs); and supporting vehicle-to-everything (V2X) communications for, e.g., connected vehicle functionalities.
