Green networks, which is put forward for the environmental and economic benefits, has
received much attention recently because of the vast energy cost in wireless cellular …

Femtocells in two-tier femto-macro networks can enhance indoor coverage and improve
overall network performance. Macro networks may share spectrum with overlaid femtocells …

Cloud radio access network (C-RAN) is deemed as a promising architecture to meet the
exponentially increasing traffic demand in a mobile network. However, it needs a huge …

We investigate the problem of multichannel allocation for small-cell users (SUs) in 5G
heterogeneous cellular networks by taking users' quality of experience (QoE) into account …

A novel modularity-based user-centric (MUC) clustering is conceived for resource allocation
in ultra dense networks (UDNs), in order to maximize the sum-rate per orthogonal resource …

We propose a blind interference alignment scheme for partially connected cellular networks.
The scheme cancels both intracell and intercell interference by relying on receivers with one …

Flexible time division duplex (TDD) is expected to be one of the key technologies for 5G
flexible air interface. The main benefit of flexible TDD is to allow for better radio resource …

Network densification is seen as a necessary trend in the evolution toward 5G networks to
cope with future high-traffic demands. In particular, the use of femtocells seems to be the …

In this paper, we address the problem of downlink resource allocation and admission control
for an Orthogonal Frequency Division Multiple Access (OFDMA)-based Cloud Radio Access …

Femtocell is a promising technology to increase network capacity and coverage, especially
in indoor areas. It has low power, short range. The Home Base Station/HeNB (Femtocell …
