An apparatus relays a signal transmitted from a specified base station to a mobile station in CDMA wireless telecommunications systems. To this purpose, the apparatus, installed in an area where signals transmitted from a plurality of base stations co-exist or a soft blocking occurs, operates by following the steps of receiving the signal transmitted from a specified base station having smaller number of calls than the other neighboring base stations, filtering a signal within a service frequency band from the received signal, amplifying the filtered signal, adjusting a gain of the amplified signal and finally transmitting the gain-adjusted signal to the mobile station. Accordingly, a pilot pollution phenomenon is removed and an effective call distribution is achieved, so that the efficiency in using system resources can be greatly improved.
