In this paper, we consider a primary/secondary spectrum-sharing system, and study adaptive resource management in cognitive radio (CR) fading broadcast channels (BC). Specifically, we propose utilizing spectrum sensing information about the primary's activity at the secondary base station for an efficient allocation of the resources, namely, transmission time and power, to the secondary users. Spectrum...
In this contribution, we address the resource allocation problem in cognitive radio (CR) broadcast channels (BC) when the radio resources are shared between the primary user of the spectrum band and the CR-BC secondary network. Specifically, we propose utilizing spectrum sensing information about the primary's activity at the secondary base station for an efficient allocation of the resources, namely,...
