The ongoing development of mobile communication networks to support a wide range of
superfast broadband services has led to massive capacity demand. This problem is …

As the services and requirements of next-generation wireless networks become increasingly
diversified, it is estimated that the current frequency bands of mobile network operators …

This paper reviews recent spectrum sharing models under study in the spectrum regulation
and wireless communications research domains. An overview of different spectrum regulator …

Traditionally, the frequency spectrum is licensed to users by government agencies in a rigid
manner where the licensee has the exclusive right to access the allocated band. Therefore …

The radio spectrum is a precious resource that underpins various wireless services. It is
traditionally regulated by a fixed frequency assignment policy, which allocates frequency …

Spectrum sharing between an existing incumbent spectrum user and an LTE/LTEAdvanced
network with conditions that resemble exclusive licensing have become an appealing …

Cellular networks today are designed for and operate in dedicated licensed spectrum. At the
same time there are other spectrum usage authorization models for wireless communication …

We study a spectrum sharing problem in an unlicensed band where multiple systems coexist
and interfere with each other. Due to asymmetries and selfish system behavior, unfair and …

Spectrum sharing mechanisms need to be carefully designed to enable inter-technology
coexistence in the unlicensed bands, as these bands are an instance of a spectrum …

Spectrum frequency is a valuable resource for wireless communication but very limited in its
availability. Due to the extensive use and ever increasing demand of spectrum bands by …
