Abstract

Scheduling schemes have been extensively studied in the framework of cellular networks, but the emergence of new system concepts, such as cognitive radio, brings this topic into the focus of research again. In this paper, we investigate multiuser uplink scheduling with quality-of-service (QoS) provisioning for multiple cognitive users working at the same area with a primary user. In this work, the proposed scheduling schemes attempt to provide a satisfactory tradeoff between maximizing the system capacity, achieving fairness among cognitive users, minimizing the interference to the primary user, and satisfying delay constraints to individual cognitive user. Simulation results are presented to evaluate the performance of the proposed scheduling schemes.
