    • In a radio communication system that simultaneously uses plural radio channels (STA1), a radio communication apparatus (11-15; 20-25) can quickly secure plural radio channels simultaneously used for radio communication while preventing collision with a radio signal transmitted by another radio communication apparatus so away from the radio communication apparatus that the radio communication apparatus cannot detect radio waves. A radio communication apparatus STA1 according to the present invention includes a receiving unit 10 which receives, when a first signal is transmitted via each of the plural radio channels (21-25), the first signal though at least one or more radio channels among the plural radio channels (11-15), and performs carrier sense for each of the plural radio channels used for the transmission of the first signal, a selecting unit 40 which selects a radio channel used for radio communication out of radio channels set in a standby state, and transmitting unit 20 which transmits a response signal for the first signal via the selected radio channel.
    • 在同时使用多个无线电信道(STA1)的无线电通信系统中,无线电通信装置(11-15; 20-25)可以快速地固定同时用于无线电通信的多个无线电信道,同时防止与另一个无线电台发送的无线电信号的冲突 通信装置远离无线电通信装置,无线电通信装置不能检测无线电波。 根据本发明的无线电通信装置STA1包括:接收单元10,当经由多个无线电信道(21-25)中的每一个发送第一信号时,接收单元10通过至少一个或多个无线电信道接收第一信号 多个无线电信道(11-15),并且对于用于发送第一信号的多个无线电信道中的每一个执行载波侦听;选择单元40,其从设置在待机状态的无线电信道中选择用于无线电通信的无线电信道 状态和发送单元20,其经由所选择的无线电信道发送用于第一信号的响应信号。
