In 5G Heterogeneous Networks (HetNet), a new generation which have multiple BSs of different types such as Femto BS and Macro BS, there is the possibility of choosing to receive the data from one BS and transmit them to a different BS, and therefore decoupling the uplink and downlink. Especially, the increasing demand for faster, more reliable, and efficient connectivity has made the optimization of User Equipment (UE) allocation in 5G networks a crucial task. To tackle the challenges posed by heterogeneous 5G networks, this study compares and evaluates the performance of Downlink/Uplink Decoupling (DUDe) and traditional Downlink/Uplink Coupled (DUCo) user allocation approaches. Simulation results show that DUDe UE allocation outperforms DUCo by providing improved network performance and more efficient utilization of network resources in diverse network conditions. These findings have important implications for the design and optimization of 5G networks and provide valuable insights for researchers and practitioners in the field.1 aTsachrelias, Konstantinos1 aGkamas, Apostolos1 aKatsigiannis, Chrysostomos-Athanasios1 aBouras, Christos1 aKokkinos, Vasileios1 aPouyioutas, Philippos  uhttp://telematics.upatras.gr/telematics/publications/optimization-user-allocation-heterogeneous-5g-networks-using-dude-techniques?language=el
