N2 - In this paper, we propose a statistical Quality-of-Service (QoS) driven power and rate allocation scheme over wireless Rayleigh fading cognitive radio links. Specifically, we consider the scenario that one secondary link coexists with one primary link by sharing particular portions of the spectrum. Our proposed power and rate allocation scheme aims at maximizing the system effective capacity, which can be seen as the maximum arrival rate supported by the secondary link subject to a given statistical delay QoS constraint. In this work, we not only take into account the average transmit and interference power constraints for the secondary link, but also consider the influence from the transmission of the primary link to the effective capacity of the secondary link. Simulation results show that, (1) the effective capacity of the secondary link decreases when the statistical delay QoS constraint becomes stringent; (2) given the QoS constraint, the effective capacity of the secondary link varies with the interference power constraint and the SNR of the primary link.
