With the expected increase in the number of connected devices, heterogeneous networks
(HetNets) technology has gained great attention in next generation wireless networks. The …

In this letter, a two-stage interference alignment (IA) scheme and a link scheduling scheme
are proposed to cooperatively address both the cross-tier and co-tier interference for …

Heterogeneous networks (HetNets) technology is expected to be applied in next generation
cellular networks to boost system capacity. However, applying HetNets introduces a …

In this paper, we investigate the interference alignment schemes for the downlink of a
heterogeneous network (HetNet), where the macro base station (BS) can serve arbitrary …

To effectively mitigate interference and improve the performance, we propose a grouping-
based two-stage distributed interference alignment (GTDIA) scheme for a two-layered …

The introduction of the relay in heterogeneous networks (HetNets) can enhance cell-edge
signals, but it will also bring coexistence of multiple interference which is composed of co …

This paper focuses on interference issues arising in the downlink of a heterogeneous
network (HetNet), where small cells are deployed within a macrocell. Interference scenario …

Interference alignment (IA) is thought to be an effective technique on reducing interference
in wireless communications. To mitigate the interference and improve the system …

Recently, heterogeneous network (HetNet) has been introduced as an appropriate strategy
to cope with the explosive growth of wireless traffic. To address the issue of severe …

In the open subscriber group (OSG) mode of heterogeneous network (HetNet), the inter
macro-user interference is the main interference to macro user equipments (UEs), and the …
