Radio communication system, radio communication apparatus, and radio communication method for radio communication system

A radio communication apparatus for performing radio communication with another radio communication apparatus, the radio communication apparatus comprising:

• a receiving unit which receives frequency information relating to a frequency band being usable by the radio communication apparatus stored in a storage apparatus;
• and
• a transmission unit which transmits to the other radio communication apparatus the frequency information received from the storage apparatus and relating to a frequency band being usable for radio communication in a region to which the radio communication apparatus moves.

A radio communication method in a radio communication system including a storage apparatus storing frequency information relating to a frequency band being usable for radio communication, a first radio communication apparatus acquiring the frequency information from the storage apparatus, and a second radio communication apparatus performing radio communication with the first radio communication apparatus, the method comprising:

• transmitting to the second radio communication apparatus the frequency information acquired from the storage apparatus and relating to a frequency band being usable for radio communication in a region to which the first radio communication apparatus moves, by the first radio communication apparatus;
• and
• receiving the frequency information from the first radio communication apparatus, by the second radio communication apparatus.
