An RF unit and a modem unit receive a packet signal, containing information regarding a frame construction, which is transmitted from a base station apparatus in a first period of a frame at least including first periods and second periods. An extraction unit identifies the second period in the frame, based on the received packet signal. A setting unit sets a waiting time period in the identified second period. A carrier sensing unit carries out carrier sensing over the waiting time period set by the setting unit. The modem unit and the RF unit broadcast the packet signal based on a result of the carrier sensing. |
