In this contribution, we derive the optimal power allocation policy in the case of an uplink multiuser system under quality of service constraints. Interestingly, using asymptotic results (in the number of users and dimensions) of random matrix theory and under the assumption of Minimum Mean Square Error Successive Interference Cancellation (MMSE-SIC) at the base station, the results show that the users requested rate can be satisfied based only on the knowledge of the statistical nature of the environment and not the channel realization as it is commonly assumed. Moreover, a framework is provided to determine the decoding order of users which minimizes the overall transmitted power. The results are then validated through simulations.
