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 …

In this paper, we propose interference alignment (IA) schemes for downlink multiple-input-
multiple-output heterogeneous networks (HetNets) with partial connectivity, which is induced …

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

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 …

Aiming to mitigate interference and enhance the network capacity, we investigate the
interference alignment (IA) for multiple-input-multiple-output (MIMO) multi-cell downlink in …

We consider a downlink heterogeneous network (HetNet), where several picocells coexist in
the same spectrum as a macrocell. For a general framework of the multiple-input multiple …

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 …

The occurrence of the intercell interference (ICI) is inevitable in downlink heterogeneous
networks because user terminals (UTs) often receive the signals transmitted from different …

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 …
