We propose a unified static framework to study the interplay of user association and
resource allocation in heterogeneous cellular networks. This framework allows us to …

Deployment of low-power low-cost small access points such as femtocell access points
(FAPs) constitute an attractive solution for improving the existing macrocell access …

For small cell technology to significantly increase the capacity of tower-based cellular
networks, mobile users will need to be actively pushed onto the more lightly loaded tiers …

In this paper, we develop a framework for user association in infrastructure-based wireless
networks, specifically focused on flow-level cell load balancing under spatially …

In heterogeneous cellular networks (HCNs), it is desirable to offload mobile users to small
cells, which are typically significantly less congested than the macrocells. To achieve …

This paper considers optimization of the user and base-station (BS) association in a wireless
downlink heterogeneous cellular network under the proportional fairness criterion. We first …

This paper investigates joint user association (UA) and user scheduling (US) for load
balancing over the downlink of a wireless heterogeneous network by formulating a network …

Wireless access to the Internet is expected to be very valuable for both individuals and the
society. However, advances in transmission technology alone may not be sufficient to …

The rate distribution in heterogeneous networks (HetNets) greatly benefits from load
balancing, by which mobile users are pushed onto lightly-loaded small cells despite the …

Merging the fundamental principles of resource allocation with the state-of-the-art in
research and application examples, Han and Liu present a novel and comprehensive …
