In this paper, the authors propose an evolution of adaptive power control algorithms for Universal Mobile Telecommunications System (UMTS). The proposed mechanism uses an adaptive power step to carry out with high fluctuations in the radio interface. Furthermore, they propose the integration of a stabilization zone where the transmitted power is kept constant to reduce oscillations around the target QoS level. In this algorithm, only the interpretation of power control feedback commands is ameliorated by adding some intelligence to mobiles and base stations. Moreover, the standardized radio interface protocol is used without modification.
