ABSTRACT:
It is an object of the present invention to provide a base station transmission-reception apparatus wherein an increase in the number of sectors does not increase the load to a control center arising from hand-over between sectors and does not increase the number of processing sections for each channel. In the apparatus, each of baseband signal processing sections 1-1 to 1-N includes a transmission signal selection circuit 202 for outputting a transmission signal from a transmission signal processing section 201 to only a sector antenna 107 indicated by a selection signal, a reception signal selection circuit 204 for selecting a reception signal of a sector indicated by the selection signal, a reception signal processing section 203 for detecting reception data corresponding to its own communication channel from the reception signal from a reception signal selection circuit 204, and a control section 207 for providing the selection signal to the transmission signal selection circuit and the reception signal selection circuit.
