Disclosed is a wireless transmission/reception apparatus for transmitting/receiving signals of multiple frequency bands according to multiple mobile communication services. The apparatus includes a transmission unit having a plurality of transmitters for transmitting the signals of the frequency bands of the mobile communication services through each transmitter, and a reception unit having a plurality of receivers for receiving signals, which correspond to an equal frequency band from among the signals of the frequency bands of the mobile communication services, through at least one receiver for receiving radio signals of different service schemes of the equal frequency band, and receiving signals not corresponding to the equal frequency band through receivers according to each frequency band. The apparatus uses one receiver capable of receiving different service signals of the same frequency band, so that the number of receivers can be reduced. Further, the apparatus enables a duplexer used only in an existing FDD scheme to be also used in a TDD scheme.
