In this paper, we present a framework to give a comprehensive review of how to improve the
spectrum utilization of millimeter-wave (mmWave) systems using indoor small cells in multi …

In this paper, we present a novel clustering‐based resource allocation framework for
downlink transmission in ultra‐dense small cell networks. Specifically, we first model a …

In this paper, we propose two spectrum utilization improvement approaches (SUIAs), namely
SUIA 1 and SUIA 2, based on whether or not the licensed 28 GHz millimeter-wave …

In heterogeneous wireless networks (HetNet), the multihomed user equipment (UE) utilizes
multiple access options (AO) simultaneously and aggregate the offered resources from …

Deploying femtocells underlaying macrocells is a promising way to improve the capacity and
enhance the coverage of a cellular system. However, densely deployed femtocells in urban …

Heterogeneous networks (HetNets) provide the demand for high data rates. In this study, we
analyze the coexistence of femtocells and device-to-device (D2D) communication with …

Heterogeneous networks (HetNets) composed of overlapped cells with different sizes are
expected to improve the transmission performance of data service significantly. User …

The current state of device-to-device (D2D) communication in the presence of cellular
network addresses two major challenges of interference as well as throughput inadequacy …

Nowadays, the demand for high-quality multimedia services (video, audio, image, and data)
is rapidly increasing. The Digital Video Broadcasting-terrestrial (DVB-T) standard, its second …

This paper presents a generic spectrum reuse model (GSRM) to reuse millimeter wave
(mmWave) and terahertz (THz) spectrum in multi-band-enabled small cells located within …
