This paper presents a detailed performance analysis of adaptive downlink resource allocation based on users' instantaneous channel responses using power minimization (PM) and bandwidth constrained power minimization (BCPM) strategies. This study shows that, in cellular systems, where interference is a dominant factor, the link outage performance of a resource allocation strategy varies significantly depending on the user channel parameters. In particular, both analytical and simulation results indicate that the PM strategy outperforms BCPM in a mild shadowing environment. However, in severe shadowing conditions, this trend is reversed. This assessment holds true for both flat and frequency-selective fading.
