<p>A structure of a BS(Base Station) sharing wireless paths among sectors in a mobile communication system and a sharing method thereof are provided to increase the capacity of the BS by applying a sector configuring scheme and sharing the wireless paths among the sectors in case that the reuse coefficient of the BS is more than three times and to reduce cost for the BS by integrating components added according to each sector configuration in the conventional. A structure of a BS(Base Station) sharing wireless paths among sectors in a mobile communication system comprises a modem unit(300), a modem signal allocating unit(350), an IF(Intermediate Frequency) processor(310), a converter(320), a front end unit(340). The modem unit(300) outputs a baseband signal to be transmitted to a terminal or inputs a received baseband signal. The modem signal allocating unit(350) allocates the baseband signals, transmitted by the modem unit(300) or the IF processor(310), to different frequency bands. The IF processor(310) converts a signal, transmitted by the modem signal allocating unit(350) or the converter(320), into an IF signal. The converter(320) performs frequency conversion such that the IF signal, outputted by the IF processor(310), is carried in a carrier wave signal or converts a signal, transmitted by the front end unit(340), into a low frequency signal. The front end unit(340) filters a noise from a signal outputted by the converter(320) or a signal received by each sector and distributes the signal, to be transmitted to the terminal, to corresponding paths of each sector.</p> |
