Simulation Based Energy Efficiency Analysis of DUDe 5G Networks

To be able to respond to the explosively increased data traffic demand of 5G and beyond networks (Internet of Things (IoT) , Voice/Video calls, Peer2Peer (P2P) software, etc.), one of the most promising technologies are densified Heterogeneous Networks (HetNets). In HetNets, base stations are brought closer to users with the placement of small base stations, which results in better spectral and energy efficiency for cellular systems. However, the HetNet topology challenges traditional cellular systems. One of the most important challenges is user association. Aiming to avoid the drawback caused by Downlink/Uplink Coupling (DUCo) access in HetNets user association, a Downlink/Uplink Decoupling DUDe Access approach has emerged. By allowing access points in the uplink and downlink association to be different, DUDe greatly improves the uplink performance of HetNets. In this paper, we evaluate energy efficiency and resource allocation of DUDe approach.
