QoS Based Power Control for Small Cell Networks

In this paper, we present a power adjustment algorithm that can be used in heterogeneous networks where varying QoS requirements of users should be taken into account. The proposed power control algorithm differs from similar approaches in the literature in the sense that channel state information is not required in the power update. The performance of the algorithm is evaluated both analytically and numerically under a setup with non-ideal communication links. Simulation results demonstrate that optimum power allocation with respect to the QoS requirements of users is achieved when using the proposed algorithm.
