An adaptive power control algorithm is proposed to minimise power control errors at mobile speeds from 0 to 80 km=h in a UMTS system. The proposed algorithm adjusts its power control step size based on a new parameter called consecutive transmit power control ratio. Simulations of the proposed algorithm show that it outperforms fixed-step algorithms without any requirements for additional knowledge such as Doppler estimations.
