Ultra dense cellular networks (UDNs) are concerned in this paper, which employ Macro-
Diversity-Coordinated Multipoint (MD-CoMP) to deal with the serious inter-cell interference …

For coordinated multipoint transmission in heterogeneous ultra dense networks (HUDN),
clustering and multicell resource scheduling should be carried out jointly. Based on the α …

In this paper, we investigate how picocells overlaid in macrocells expand their coverage
areas under different Cell Range Expansion (CRE) strategies in a macro-pico …

Ultra dense networks (UDN) can be considered as one of the key technologies of 5G, since
it can improve capacity and spectral efficiency. With the densification of cell networks, the …

This work investigates the performance of user-centric joint transmission coordinated
multipoint (JT-CoMP) clustering in a control/data decoupled cell-less architecture taking …

Ultra dense network (UDN) technology will certainly be the key to the future development of
the fifth Generation (5G) mobile communication. In order to improve spectral efficiency and …

Coordinated Multi-point (CoMP) transmission has long been known for its ability to improve
cell edge throughput. However, in a CoMP cellular network, fixed CoMP clustering results in …

In this paper, a joint user association (UA) scheme with JP-CoMP using a hybrid self-
organizing network (SON) is proposed for a practical clustered heterogeneous cellular …

The ongoing densification of small cells, ie, ultimately evolving toward ultra-dense networks
(UDNs), yields an unprecedented paradigm shift in network design by bringing the base …

Due to the irregular topology of ultra dense cellular network (UDN), base station (BS)-centric
methods are usually with low spectrum efficiency and not flexible for quality-of-service (QoS) …
