Abstract:
1. A radio communication apparatus performing time division duplex alternately switching a transmission period and a reception period by time dividing an identical frequency, the radio communication apparatus comprising: an antenna commonly used for transmission and reception; a transmitter unit that is coupled to the antenna and outputting a transmission signal; a receiver unit that is coupled to the antenna and the transmitter unit, and processing a reception signal received by the antenna; a switch capable of switching between an operation for the transmission period to cut off inflow of the transmission signal to the receiver unit and an operation for the reception period to cut off inflow of the reception signal to the transmitter unit; a signal detector unit that detects the transmission signal; and a controller unit that calculates a deviation time for a detection timing at which the transmission signal is detected by the signal detector unit from a preset fixed periodic timing, and controlling switchover timing of the switch based on the deviation time, wherein, when the detection timing in a first transmission period is later than the preset fixed periodic timing, and the deviation exceeds a predetermined time, the controller unit delays a switchover timing from a next reception period relative to the first transmission period to the next transmission period thereto by a predetermined adjustment time.
