Backhaul-aware Joint User Association and Resource Allocation for Energy-constrained HetNets
Cellular networks are now rapidly evolving to the renewable heterogeneous network (HetNet) architectures, where a mixture of macro base stations (BSs) and small cell BSs coexist. Particularly, these BSs are partly-powered or self-powered by renewable energy sources (RES). In this context, joint user association and resource allocation is challenging. In addition, wireless backhaul is rapidly be...
متن کاملBackhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets
Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...
متن کاملUser Association in over- and under- provisioned Backhaul HetNets
Operators, struggling to continuously add capacity and upgrade their architecture to keep up with data traffic increase, are turning their attention to denser deployments that improve spectral efficiency. Denser deployments make the problem of user association challenging, and much work has been devoted to finding algorithms that strike a tradeoff between user quality of service (QoS), and netw...
متن کاملBackhaul aware joint uplink and downlink user association for delay-power trade-offs in HetNets with hybrid energy sources
In cellular networks, conventional user association algorithms are solely based on downlink (DL) performance, which may lead to inefficient transmission power and high interference in the uplink (UL) transmission. In addition, the backhaul data rate constraint has been neglected by the majority of the existing user association algorithms. However, the backhaul constraint has become more severe ...
متن کاملOptimal Hierarchical Radio Resource Management for HetNets with Flexible Backhaul
Heterogeneous networks (HetNets) have been considered as a promising architecture for upcoming 5G networks due to their high energy and spectrum efficiency. However, providing backhaul connectivity for all macro and pico base stations (BSs) in HetNets constitutes a significant share of infrastructure cost. Recently, the idea of flexible backhaul has drown a lot of attention both from industry a...
