On the usefulness of outer-loop power control with successive interference cancellation

In this paper we investigate FER-based outer-loop power control for Successive Interference Cancellation. Specifically, we show that for unlimited mobile powers, FER-based outer-loop power control will drive the received powers to the power profile required to achieve equal performance. Further, when we consider power limits for specific mobiles, we find that individual mobile limits will not affect the performance of other signals and based on limited simulation results, the system appears to be stable in the presence of such limits.
