We consider joint optimization of user-to-base-station (BS) association, and time-frequency
resource block (RB) and power allocation in heterogeneous networks (HetNets). The …

This paper addresses the joint User Association (UA) and power minimization in the
downlink of a two-tier Heterogeneous Network (HetNet). Macro Base Stations (MBSs) apply …

This paper addresses a joint downlink and uplink aware cell association problem in a multi-
tier heterogeneous network in which base stations (BSs) have finite number of resource …

A heterogeneous network (HetNet) can actively utilize the spectrum reuse with low power
consumption, and thus is promising for the next-generation cellular networks. However …

The objective of this work is to determine a close-to-optimal user-to-base station (BS)
association that maximizes the number of users served by the downlink of a heterogeneous …

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 consider a heterogeneous network (HetNet) containing primary users (PUs) and
secondary users (SUs). Ordinary cellular users are characterized as PUs, while SUs are the …

This work presents a joint design of user association and resource allocation in a
heterogeneous network, which is comprised of a single macro base station and a group of …

In this paper, a user association and bandwidth allocation approach is proposed for
heterogeneous networks (HetNets) using fuzzy logic controllers. Due to the heterogeneous …

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 …
