In this paper, assuming transmission with fixed rate and fixed power, the authors derive the average duration of capacity outage and non-outage events of selective decode-and-forward relaying with repetition coding over slow Rayleigh fading channels. Furthermore, they develop high Signal-to-Noise Ratio (SNR) approximations for both durations which provide significant insight into the impact of various system and channel parameters. For high SNR, on a double logarithmic scale, both the Average Outage Duration (AOD) and the Average Non-Outage Duration (ANOD) become straight lines when plotted as functions of the SNR.
