PURPOSE: A method for controlling power levels of transceiving signals in a wireless subscriber interfacing device is provided to linearize non-linear factors influencing a transceiving power control, according to a pause control model, so as to adaptively control transceiving power levels of the wireless subscriber interfacing device through the linearizing process. CONSTITUTION: A wireless subscriber interfacing device inputs fundamental data extracting data according to each set, and extracts system characteristics(410,412). The interfacing device generates a system model by using the extracted data, and finds a linearized formula(I) which does not perform a control and a linearized formula(II) capable of performing a control(414). The interfacing device decides whether error ranges of the sets are within required ranges according to the linearized formulas, by using the extracted data(416). If not, the interfacing device extends the number of sets for being used as samples to repeatedly perform the operation of the step '412'(417). If the error ranges are within the required ranges, the interfacing device finds a relation between an input variable and an output variable, which is appropriate for the system model, by using the linearized formula(II)(418). The interfacing device performs a set compensation according to the formula(II)(420). If measured values of the sets and the linearized formulas are applied, and if the error ranges are out of limitations, the interfacing device controls levels of maximum values and minimum values of the sets through a compensation model parameter linearization(II) operation, and repeatedly performs(422). If the error ranges are not out of the limitations, the interfacing device performs a down processing for a program(P/G) of every set(424).
