The joint user association and spectrum allocation problem is studied for multi-tier
heterogeneous networks (HetNets) in both downlink and uplink in the interference-limited …

This paper develops a new approach to the modeling and analysis of heterogeneous
cellular networks (HetNets) that accurately incorporates coupling across the locations of …

We model and analyze heterogeneous cellular networks with multiple antenna BSs (multi-
antenna HetNets) with K classes or tiers of base stations (BSs), which may differ in terms of …

Current resource allocation techniques in cellular networks are largely based on single-
slope path loss model, which falls short in accurately capturing the effect of physical …

Load balancing by proactively offloading users onto small and otherwise lightly-loaded cells
is critical for tapping the potential of dense heterogeneous cellular networks (HCNs) …

This paper proposes joint user association and energy-efficient resource allocation in the
uplink of multi-user two-tier Orthogonal Frequency Division Multiplexing (OFDM) …

This paper studies the joint user association and resource allocation in heterogeneous
networks (HetNets) from a novel perspective, motivated by and generalizing the idea of …

We address the resource allocation problem in an LTE-based 2-tier heterogeneous network
where in-band D2D communications are supported under network control. The different …

Heterogeneous cellular networks (HetNets) are to be deployed for future wireless
communication to meet the ever-increasing mobile traffic demand. However, the dense and …

In this paper, we consider the intercell interference coordination (ICIC) problem in
heterogeneous cellular networks with randomly deployed small-cell base stations (BSs) …
