The performance of heterogeneous networks (HetNets) is investigated with both direct and
relay-aided transmission strategies in a macrocell. We first propose an interference …

In this paper, we propose an interference alignment and cancelation (IAC) scheme for the
uplink of heterogeneous networks (HetNets). Due to the random deployment of small cells …

In heterogeneous cellular networks, small cells provide for the handover of users from the
macro cell and organize itself during the transmission. This paper studies the downlink …

At present, operators address the explosive growth of mobile data demand by densification
of the cellular network so as to reduce the transmitter-receiver distance and to achieve …

Two‐tier heterogeneous networks, where the current cellular networks, that is, macrocells,
are overlapped with a large number of randomly distributed femtocells, can potentially bring …

Interference management for heterogeneous networks (HetNets) has been a research
highlight in recent years; one effective method is interference avoidance by resource …

This paper proposes interference cancellation that utilizes relay stations (RSs). In Long Term
Evolution (LTE) Advanced, heterogeneous networks in which femto and picocells are …

It is an urgent task to overcome challenge in interference management for macro cellular
with low-power base stations (BSs), such as relay, pico, and femto called subnet nodes. In …

With macrocell base stations (MBSs) providing basic coverage for mobile users, the multiple
tiers of cache-enabled small-cell base stations (SBSs) can opportunistically form user …

To improve energy efficiency and reduce the interference to macro users (MUs), this paper
investigates the robust resource allocation (RA) problem for maximizing the interference …
