Abstract
This paper gives an optimal step size of E$\sub$b/ /I$\sub$oT/ for outer-loop power control(OLPC) in IMT-2000 system. The performance of outer-loop Power control is affected greatly by the fixed step size according to the channel environments. Conventional methods are inaccurate because they are decided by expert's experiences and the performance is not proved theoretically. In this paper, we show that IMT-2000 system maintains optimal capacity and QoS by the step size of E$\sub$b/ /I$\sub$oT/ obtained from the discrete-time Markov chain model.
