Wireless communication system, relay apparatus, wireless communication method and program

A relay apparatus in a wireless communication system with a first communication apparatus, a second communication apparatus, and the relay apparatus moving, the relay apparatus comprising:

• a transmission data controller that determines a frequency bandwidth according to a relay apparatus position, the frequency bandwidth being used for a first signal transmitted from the first communication apparatus, on a basis of information regarding a number of first communication apparatuses with which the relay apparatus communicates at the relay apparatus position, and transmits band information indicating a frequency band selected on a basis of the frequency bandwidth from a radio frequency band that can be used for the first signal to the first communication apparatus;
• a first signal receiver that receives the first signal transmitted by the first communication apparatus at a frequency included in a radio frequency band indicated by the band information and acquires waveform data of the first signal received;
• and
• a second signal transmitter that transmits the waveform data acquired by the first signal receiver to the second communication apparatus by a second signal.

A wireless communication method executed by a wireless communication system with a first communication apparatus, a second communication apparatus, and a relay apparatus moving, the wireless communication method comprising:

• determining, by a transmission data controller, a frequency bandwidth according to a relay apparatus position, the frequency bandwidth being used for a first signal transmitted from the first communication apparatus, on a basis of information regarding a number of first communication apparatuses with which the relay apparatus communicates at the relay apparatus position, and transmitting band information indicating a frequency band selected on a basis of the frequency bandwidth from a radio frequency band that can be used for the first signal to the first communication apparatus;
• transmitting, by the first communication apparatus, the first signal having a frequency included in the frequency band indicated by the band information;
• receiving, by the relay apparatus, the first signal transmitted by the first communication apparatus and acquiring, by the relay apparatus, waveform data of the first signal received;
• transmitting, by the relay apparatus, the waveform data acquired by the relay apparatus to the second communication apparatus by a second signal;
• receiving, by the second communication apparatus, the second signal transmitted from the relay apparatus;
• performing, by the second communication apparatus, reception processing of the second signal received and acquiring, by the second communication apparatus, the waveform data;
• and
• performing, by the second communication apparatus, reception processing of the first signal indicated by the waveform data acquired by the second communication apparatus and acquiring data set to the first signal by the first communication apparatus.
