  • Publication number: 20230328776
    Abstract: A wireless communication method in a wireless communication system includes carrier sense processing for determining whether a carrier sense band is in a busy state or an idle state on the basis of a reception state of a reception signal in the carrier sense band before transmitting a transmission signal using a transmission channel. The carrier sense band is set so as to include not only a transmission channel band which is a frequency band of a transmission channel but also an adjacent carrier sense band adjacent to the transmission channel band. When it is determined that the carrier sense band is in an idle state, transmission processing for transmitting a transmission signal by using a transmission channel is performed.
