PROBLEM TO BE SOLVED: To provide a radio base station unit that can compensate a fault in a short time, without increasing the processing quantity on the occurrence of the fault in a radio signal transmission reception section. SOLUTION: Each of the radio signal transmission reception sections 20-1 to 20-n entirely manages operation information used respectively by a plurality of sectors, selects desired operation information from among them and transmits/ receives data through a sector, corresponding to the operation information. Furthermore, a standby radio signal transmission reception section among the wireless signal transmission reception sections 20-1 to 20-n recognizes the operating state of the other radio signal transmission reception sections via a state information shared line 62 and the standby radio signal transmission reception section uses the operation information corresponding to the sector, through which the faulty radio signal transmission reception section has transmitted/ received data and transmits/receives data through the sector on the occurrence of the fault in the other radio signal transmission reception section. |
