networks, ie a network of … picocell base stations, where each tier serves a disjoint set of …

… In this paper, we focus on the downlink power control of a simplified heterogeneous network
consisting of one MBS, multiple FBSs and user equipments (UE) in both tiers (see Fig. 1). …

… networks (SONs) can help to manage the severe interference in dense heterogeneous
networks (… In this paper, a HetNet is modeled as a dense two-tier network with conventional …

… Abstract—In a two-tier heterogeneous network (HetNet) where small base stations (SBSs) …
tion due to the inter- and intra-tier interferences. Introducing cognition into the SBSs through …

… heterogeneous networks (HetNet) have been widely studied as an effective approach to
provide high network … energy efficiency of a two-tier heterogeneous network consists of a macro-…

… two-tier heterogeneous cellular networks, with wireless backhaul communication, consisting

… In this work, we study a two-tier heterogeneous network (HetNet) where the macro tier and
small cell tier both operate dynamic TDD and use orthogonal frequency bands. We propose a …

… (SISO) network. Therefore, to study the gain provided by the DL and UL decoupling in
multi-antenna base stations (BSs) setup, we study a two tier heterogeneous network consisting of …

… In this paper, we studied the resource allocation problem in two-tier heterogeneous
networks. Due to the non-convex property of constraints and the objective function, the original …
