1. 21. 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.

3. 22. 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.

   Sammanfattning : Cyber-Physical Systems (CPSs) are becoming ubiquitous in modern society, enabling new applications that rely on the seamless interaction between computing, communication, and physical processes. In this context, ultra-reliable low-latency communications (URLLC) emerges as a crucial element, reliably allowing the real-time exchange of critical data. LÄS MER

5. 24. Single Base Station mmWave Radio Positioning, Mapping, and SLAM

   Författare :Yu Ge; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DA; positioning; 5G; experimental validation; RFS; SLAM; fusion; mmWave; diffuse multipath; mapping; single BS;

   Sammanfattning : Fifth-generation (5G) communication systems in Frequency Range 2, operating above 24 GHz and utilizing mmWave signals, showcase distinct properties that open up new possibilities in positioning, mapping, and simultaneous localization and mapping (SLAM). The combination of large bandwidth, extensive antenna arrays, and high carrier frequency results in geometric-based signals, and unprecedented delay and angle resolution. LÄS MER

7. 25. Towards a Scalable and Low-Latency Softwarized Mobile Packet Core Network

   Författare :Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Christian Esteve Rothenberg; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile Packet Core; Evolved Packet Core; 5G; SDN; NFV; Scalability; Control Plane; User Plane; MME; UPF; VPP; Load Balancing; Auto-Scaling; Time-Critical; Low-Latency; Smart Grid; GOOSE; Computer Science; Datavetenskap;

   Sammanfattning : The mobile packet core – a central part of the overall mobile cellular network – has a long history of evolution. Through the years, its architecture has been drastically changed to meet the demand coming from the fast growth in the number of devices as well as the introduction of new types of applications and services.
