Power control (PC) refers to the possibility to modify the transmission power with the aim of reducing co-channel interference and improve the system capacity. This paper describes the results of a dynamic simulation model used to analyze the behavior of different slow power control mechanisms in the time division/code division multiple access (TD/CDMA) system. As a performance measure the carrier-to-interference ratio (CIR) outage probability is used. Two types of slow power control algorithms have been implemented: (i) PC based on power received from the transmitter (level-based PC), and (ii) PC based on CIR at the receiver (CIR-based PC). The results have shown that in terms of system capacity the optimal target of the CIR-based PC is dependent on the traffic density while the target of the level based is independent from the system load
