<p>PROBLEM TO BE SOLVED: To provide a technique for reducing collision probability of a packet signal.SOLUTION: A processing section 26 regulates such that a base station device is able to transmit a first type signal during a period of the beginning of each sub-frame and a terminal device is able to transmit a second type signal during a period of un-transmission of the first type signal in a frame. Also, the processing section 26 receives a first type signal from another base station device and a second type signal from the terminal device. Based on a received first type signal, a first specifying section 32 specifies a sub-frame used in another base station device. A second type signal includes information about the sub-frame when the terminal device receives a first type signal from another base station device. Based on information about a sub-frame, a second specifying section 34 specifies a sub-frame used in another base station device. Based on sub-frames specified in the first and second specifying sections 32 and 34, a third specifying section 42 specifies a sub-frame to be used.</p> |
