There are various definitions of wireless channel capacity, depending on whether capacity characterizes the maximum rate averaged over all fading state or maximum constant data rate that can be maintained over all fading states. Between these definitions, outage capacity is a high requested one, since it is a more appropriate definition for delay constrained applications like voice and video. Hence, maximizing this type of capacity would be more concerned. In this paper outage capacity is maximized over cut-off fading states above which transmission should be maintained. The problem is studied for Rayleigh flat fading channel where channel side information (CSI) is known at transmitters and receivers. Optimization problem is solved for both single user and multiuser channel. Numerical results will be shown as the maximum outage capacities and the associated cut-off fading states for either of the channels.
