QoS-driven user association for load balancing and interference management in HetNets


In this paper, we investigate how to jointly optimize the Almost Blank Subframe (ABS) ratio computation and the user association in Heterogeneous Networks (HetNets) while considering both the load of each BS and the users' QoS requirements. Our problem is a combinatorial NP-hard one. To solve it, we propose a centralized heuristic algorithm that aims to… (More)
