A Comparison between Network-Controlled Repeaters and Reconfigurable Intelligent Surfaces
Network-controlled repeater (NCR) has been recently considered as a study-item in 3GPP Release 18, and the discussions are continuing in a work-item. In this paper, we introduce the concept of...
On Integrated Access and Backhaul Networks: Current Status and Potentials
In this paper, we introduce and study the potentials and challenges of integrated access and backhaul (IAB) as one of the promising techniques for evolving 5G networks. We study IAB networks from...
Constrained Deployment Optimization in Integrated Access and Backhaul Networks
Integrated access and backhaul (IAB) is one of the promising techniques for 5G networks and beyond (6G), in which the same node/hardware is used to provide both backhaul and cellular services in a...
On Topology Optimization and Routing in Integrated Access and Backhaul Networks: A Genetic Algorithm-based Approach
In this paper, we study the problem of topology optimization and routing in integrated access and backhaul (IAB) networks, as one of the promising techniques for evolving 5G networks. We study the...
Uplink Power Control in Integrated Access and Backhaul Networks
Integrated access and backhaul (IAB) network is a novel radio access network (RAN) solution, enabling network densification for 5G and beyond. In this paper, we use power control combined with...
Beamforming in Wireless Coded-Caching Systems
Increased capacity in the access network poses capacity challenges on the transport network due to the aggregated traffic. However, there are spatial and time correlation in the user data demands...
Integrating Reconfigurable Intelligent Surfaces (RISs) into Indoor D-MIMO Networks for 6G
Joint Scheduling and Throughput Maximization in Self-backhauled Millimeter Wave Cellular Networks
User-Mobility-Aware Optimization of Fiber Placement in Hybrid Fiber-IAB Networks
Metaheuristic optimization of hybrid fiber-IAB networks demonstrates that integrating user dynamics into topology design enables more adaptive and cost-efficient backhaul architectures,...
Energy-Efficient FSO Reconfiguration under User Mobility in Hybrid Fiber-IAB Backhaul
User mobility creates stochastic, time-varying backhaul demand that static capacity provisioning cannot match. We propose a closed-loop, load-aware hysteresis controller for hybrid fiber-IAB-FSO...
Joint Fiber and Free Space Optical Infrastructure Planning for Hybrid Integrated Access and Backhaul Networks
Integrated access and backhaul (IAB) is one of the promising techniques for 5G networks and beyond (6G), in which the same node/hardware is used to provide both backhaul and cellular services in a...
RIS-Assisted D-MIMO for Energy-Efficient 6G Indoor Networks
We propose an alternating optimization framework for maximizing energy efficiency (EE) in reconfigurable intelligent surface (RIS) assisted distributed MIMO (D-MIMO) systems under both coherent...
