Spectrum leasing is a novel promising technique to improve the spectrum efficiency (SE)
through the spectrum owner leasing its free or under-utilization spectrum to unlicensed …

Most work on wireless network resource allocation use physical layer performance such as
sum rate and outage probability as the figure of merit. These metrics may not reflect the true …

When femto cells of different network operators do not generate harmful interference to each
other, they may agree to aggregate their spectral resources and share spectrum. While this …

Spectrum sharing provides a rapid migration pathway toward 5G by enabling the
coexistence of 4G LTE and 5G new radio (NR) that share the same spectrum. Due to …

This paper presents dynamic spectrum sharing protocol, in which operators lease or borrow
their spectrum depending on traffic load condition over unit time. To achieve this, a spectrum …

Current evolution of 5G heterogeneous network (HetNet) leads to unprecedented traffic
demands and user quality of service requirements. It is extremely challenging to meet these …

It is widely accepted that with the rollout of LTE (Long Term Evolution), multiple 3GPP (3rd
Generation Partnership Project) networks including GSM (Global System for Mobile …

Spectrum sharing has been recently proposed as a promising paradigm to improve the
efficiency of resource usage in next generation mobile networks. In particular, non …

Even though dynamic cell switching is a prominent approach for energy optimization in
heterogeneous wireless communication networks, it results in spectrum under-utilization as …

Efficient spectrum resource allocation in wireless heterogeneous networks is important for
improving the system throughput and guaranteeing the user's Quality-of-Service (QoS). In …
