One of the approaches in cognitive radio is the opportunistic spectrum access (OSA), which enables secondary users (SUs) to access the licensed frequency bands that are detected to be idle. Though there have been a few updates on the throughput aspects of SUs in OSA not much work has been done taking into account the sensing errors, spectrum occupancy probabilities as well as the transmission frame structure. In particular, it'll be interesting to investigate what happens if there is a change in the spectrum occupancy status during SU transmission period (status transition). In this short paper, we provide expressions for the achievable throughputs from these perspectives (assuming both the scenarios of no channel status transition and a status transition) for a SU. We consider a multiband channel structure. Simulation results are presented to verify our analysis.
