Abstract
In this work, we propose to configure uplink access to the macro in almost blank subframes (ABSs) improving the its utilization. The ABSs based on Downlink and Uplink Decoupled (DUDe) are modeled as an energy-efficient optimization problem in Heterogeneous Networks (HetNets). The formulation is a mixed integer programming problem so that we provide a suboptimal algorithm. Simulation study show our proposed algorithm demonstrates better performance according to energy efficiency and capacity.
