Claim:
A wireless communication apparatus configured to avoid mutual interference between wireless communication systems, comprising: a measurement unit configured to measure a channel state of a transmission timeslot to be allocated, for a switching time of a reception mode and a transmission mode; a judgment unit configured to judge a data transmission on the basis of the channel state of the transmission timeslot measured in the measurement unit; and a control unit configured to maintain a reception mode even after receiving data, and to change a frequency of a wireless communication system to a frequency of a channel of a transmission timeslot to be allocated, wherein the judgment unit decides the data transmission on basis of the measurement result of the channel state, and re-measures the channel state to re-judge the data transmitted on the basis of the re-measurement result of the channel state, and the control unit outputs a signal for performing a transmission operation of the data according to the judgment of the judgment unit.
