A Pricing-based Joint Scheduling of Pushing and on-Demand Transmission Over Shared Spectrum

摘要

Proactive pushing holds the promise of significantly improving spectrum efficiency. However, we are confronted with challenges including increasingly scarce spectrum resources and extra costs of pushing. As a result, the spectrum should be carefully shared between proactive pushing and on-demand transmission to avoid waste of resources. In this paper, we take into account the constraints of spectrum resources. We consider a pricing-based resource scheduling so that we can make a profitably efficient use of the limited spectrum resources. To maximize the income of content providers, we formulate a non-linear optimization problem, which is linearized to be more tractable. Numerical results demonstrate that appropriate pushing can bring significant gain on the income with scarce spectrum resources.
