This paper deals with the average outage duration (AOD) of wireless communication systems subject to co-channel interference. In particular, it presents closed-form expressions for the AOD when a minimum desired signal power requirement is specified for satisfactory reception. The results are quite general and accounts for systems operating over Rician and/or Nakagami fading environments. When applicable these new expressions are compared to those previously reported in the literature dealing with the AOD of (i) interference-limited systems when both the desired and interfering signals are subject to Rayleigh type of fading and (ii) power-limited systems operating over Rician or Nakagami fading channels. Corresponding numerical examples that illustrate applications of the results are also provided and discussed. These results show that specifying a certain minimum desired signal power requirement induces a floor on the AOD. They also show that the AOD is essentially affected by the the maximum Doppler frequencies (or equivalently the speed) of the desired users.
