Due to a growth of the amount of mobile phones and, at the same time, increased data rates,
the need for radio resources is proliferated. Since the spectrum is a finite resource, allocated …

The dense and pervasive deployment of wireless small cells can boost the performance of
existing macrocellular networks; however, it poses significant challenges pertaining to the …

The growing demand in indoor small cell networks has given rise to the concept of micro-
operators (MOs) for local service delivery. We model and analyze a spectrum sharing …

This paper provides a broad overview of a number of approaches to dynamic spectrum
sharing, and presents a specific case study involving hierarchical co-channel macro-and …

The exponential growth of services demands further increase of spectral efficiency which
drives the next generation wireless access networks towards deploying femtocells with …

Recent advances in self-interference cancellation enable radios to transmit and receive on
the same frequency at the same time. Such a full duplex radio is being considered as a …

In the view of spatial statistical average, when users are associated with their nearest small
base stations (SBSs), they are mainly interfered by their second closest SBSs, especially for …

This paper studies downlink resource reuse schemes for cellular networks with coexisting
femtocells and macrocells. We examine two reuse schemes, termed split reuse and shared …

We consider a multiple femtocell deployment in a small area which shares spectrum with the
underlaid macrocell. We design a joint energy and radio spectrum scheme which aims not …

We present a novel graph-based resource allocation and interference coordination
framework to mitigate downlink interference in small cell networks. In our scheme, two types …
