The success of LTE heterogeneous networks (HetNets) with macrocells and picocells
critically depends on efficient spectrum sharing between high-power macros and low-power …

The users at cell edge of a massive multiple-input-multiple-output (MIMO) system suffer from
severe pilot contamination (PC), which leads to poor quality of service (QoS). To enhance …

Enhanced Inter-cell Interference Co-ordination (eICIC) is a time-domain multiplexing
technique for improving the performance of legacy co-channel Heterogeneous Networks …

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 …

In massive multiple-input multiple-output (MIMO) systems using a large number of antennas,
it would be difficult to connect high-resolution analog-to-digital converters (ADCs) to each …

In LTE-Advanced, macro-pico heterogeneous networks (HetNet) are extensively discussed.
Cell range expansion (CRE) and inter-cell interference coordination (ICIC) are introduced to …

In this paper, we investigate an interference management scheme relying on multiple
