1. 6. 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. 7. 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.

4. 8. 5G Backhauling with Software-defined Wireless Mesh Networks

   Författare :Ricardo Santos; Andreas Kassler; Rui L. Agar; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SDN; wireless backhaul; heterogeneous networks; mmWave; 5G; resiliency; Computer Science; Datavetenskap;

   Sammanfattning : Current technological advances have caused an exponential growth of the number of mobile Internet-connected devices, along with their respective traffic demands. To cope with this increase of traffic demands, fifth generation (5G) network architectures will need to provide multi-gigabit capacity at the access base stations (BSs), through the deployment of ultra-dense small cells (SCs) operating with millimeter-wave (mmWave) frequencies, e.

5. 9. Resource Allocation in Downlink Coordinated Multi-Point Systems

   Författare :Jingya Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backhaul latency; Coordinated multi-point CoMP transmission; imperfect synchronization; fractional frequency reuse; resource allocation; general duality theory; imperfect channel state information; inter-cluster interference coordination;

   Sammanfattning : The raised user expectations of quality of service and the rapid growth of the data traffics impose a great challenge for mobile communication systems. The performance, e.g., the spectrum efficiency, peak data rate, cell-edge data rate, of current cellular systems ismainly limited due to the presence of inter-cell interference. LÄS MER

7. 10. Design Aspects of Coordinated Multipoint Transmission : A Study of Channel Predictions, Resource Allocation, User Grouping and Robust Linear Precoding for Coherent Joint Transmission

   Författare :Rikke Apelfröjd; Mikael Sternad; Anders Ahlén; Antti Tölli; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network MIMO; Centralized CoMP; Robust beamforming with imperfect CSI; Limited backhaul; Linear predictions of OFDM channels; Kalman filters; Predictor antennas; Long term channel prediction; Local resource allocation and user grouping; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : Shadowed areas and interference at cell borders pose great challenges for future wireless broadband systems. Coordinated Multipoint (CoMP) coherent joint transmission has shown the potential to overcome these challenges by turning harmful interference into useful signal power. LÄS MER
