An apparatus and method for expanding a service area of a code division multiple access (CDMA) system restricted in terms of timing. The service area of a CDMA mobile communication system, which is defined by a radius longer than a radius of a communication supported area, namely, a cell, restricted in terms of timing due to the hardware of a base station modem ASIC equipped in the system, is radially divided into a plurality of radial zones by a constant distance not longer than a maximum possible cell radius allowed by the base station modem ASIC. In accordance with the present invention, signal processing units are used which are configured in such a fashion that one of them covers the entire zone of the service area in regard to forward links from an associated base station to mobile stations in different zones of the service area while covering only the zone nearest to the base station in regard to reverse links from the mobile stations to the base station. The remaining signal processing units cover reverse links associated with the remaining zones of the service area, respectively. By such a configuration, it is possible to extend the radius of the cell limited in terms of timing.
