PROBLEM TO BE SOLVED: To confirm a reception error due to the interference and to reduce the power consumption of a mobile terminal device by expanding reception level intensity measurement to over slots only when the reception error is generated and eliminating asynchronous interference. SOLUTION: For example, a PS (mobile terminal device) 2 of a TDMA/TDD radio communication system has a radio communication with a master device 1 by using, for example, a slot 2 and a reception error is generated once owing to the interference from a slot 1 or 3. In this case, the measurement of reception level intensity which is carried out in the timing level of a reception slot center for reception level intensity display is expanded by winding the width of an RX-ON signal. Consequently, the occurrence of the reception error in the presence of an asynchronous interference wave approaching even the adjacent slots 1 and 3 can be detected and the channel slots can smoothly be switched. |
