* Paper Abstract:
In this paper, a novel transmission protocol is proposed based on the classical  Selective-Repeat Hybrid Automatic Repeat to access a primary user (PU) channel, which is referred to as the CSR-HARQ.
We assume that the PU transmits information based on time-slots (TSs). During a TS, the cognitive radio (CR) transmitter first senses the PU channel. Once a free TS is found, it transmits a number of
packets to the CU receiver based on the principles of the SR-HARQ. In this paper, we analyze the throughput, average packet delay and end-to-end packets delay of the CSR-HARQ. We proposed a pair of 
analytical approaches. The first one is probability based, while the second one relies on the classic discrete time markov chain (DTMC) principles. Finally, we study the throughput, average packet delay
as well as the  end-to-end packet delay  of the CSR-HARQ  both by simulations and by evaluating our  formulas. The  simulation-based studies  agree well with the analytical results. The performance of the
CSR-HARQ systems is significantly impacted by the activity of the PU channel  and by the reliability of the spectrum sensing.
