Wireless communication system, wireless communication apparatus and wireless communication method

A wireless communication method comprising:

• receiving a wireless signal from another wireless communication apparatus via a wireless transmission path;
• detecting disconnection of a wireless line connected to said another wireless communication apparatus;
• selecting a modulation scheme, enabling communication under poor conditions in a transmission path, rather than a modulation scheme which has been used in wireless communication when the disconnection of the wireless line is detected;
• and
• notifying the selected modulation scheme to said another wireless communication apparatus, which thus adopts it to generate a transmitting signal to a current apparatus.

A wireless communication method implemented by a wireless communication system including a first wireless communication apparatus and a second wireless communication apparatus which perform wireless communication via a wireless transmission line, said wireless communication method implementing the steps in which:

• said first wireless communication apparatus receives a wireless signal from said second wireless communication apparatus via the wireless transmission path;
• said first wireless communication apparatus detects disconnection of a wireless line connected to said second wireless communication apparatus;
• said first wireless communication apparatus selects a modulation scheme, enabling communication under poor conditions in a transmission path, rather than a modulation scheme which has been selected in wireless communication when the disconnection of the wireless line is detected;
• said first wireless communication apparatus notifies the selected modulation scheme to said second wireless communication apparatus;
• said second wireless communication apparatus receives notification indicating the selected modulation scheme from the first wireless communication apparatus;
• and
• said second wireless communication apparatus transmits signals to said first wireless communication apparatus based on the selected modulation scheme which is received.
