An apparatus for receiving data transmitted over fundamental channels having a predetermined frame offset for a plurality of mobile stations and supplement al channels assigned in association with the fundamental channels. In the apparatus, a timing generator receives a frame offset of the fundamental channel, a frame offset of the supplemental channel and a system time, outpu ts the system time delayed by the frame offset of the fundamental channel as a fundamental channel boundary signal, and outputs the system time delayed by the frame offset of the supplemental channel as a supplemental channel boundary signal. A first symbol combiner combines multi-path symbols transmitted over the fundamental channel. A second symbol combiner combines multi-path symbols transmitted over the supplemental channel. A first deinterleaver receives the symbols and the fundamental channel boundary sign al from the first symbol combiner, and deinterleaves the symbols from the first symbol combiner in a frame unit determined by the fundamental channel bounda ry signal. A second deinterleaver receives the symbols and the supplemental channel boundary signal from the second symbol combiner, and deinterleaves t he symbols from the second symbol combiner in a frame unit determined by the supplemental channel boundarysignal.
