1. A wireless communication apparatus for bidirectional wireless communication, comprising:

  • a reception section configured to receive a wireless transmission signal and produce therefrom a reception signal;

    a first oscillator configured to produce a signal having a frequency upon which reception processing is based, where the reception signal is injected into the first oscillator;

    a frequency locking detection unit configured to detect whether the frequency of the signal of the first oscillator is frequency locked with a carrier frequency of the reception signal,wherein, if the frequency locking detection unit detects that oscillation frequency of the signal of the first oscillator is frequency-locked with the carrier frequency of the reception signal, the second wireless communication apparatus transmits a communication enable signal.
