Wireless communication system, wireless communication method, and wireless device

A wireless communication method to transmit a plurality of pieces of user data from a transmission device to a reception device by using a plurality of frequency channels, the method comprising:

• dividing each of the plurality of pieces of user data into predetermined units;
• distributing each of the plurality of pieces of user data divided such that each of the plurality of pieces of user data is included in each of the plurality of frequency channels;
• transmitting the plurality of pieces of user data distributed for each of the plurality of frequency channels;
• receiving the plurality of pieces of user data transmitted for each of the plurality of frequency channels;
• extracting each of the plurality of pieces of user data received for each of the predetermined units from each of the plurality of frequency channels;
• and
• combining each of the plurality of pieces of user data extracted for each user and reproducing the combined user data.

A wireless device that transmits a plurality of pieces of user data by using a plurality of frequency channels, the wireless device comprising:

• division circuitry configured to divide each of the plurality of pieces of user data into predetermined units;
• distribution processing circuitry configured to distribute each of the plurality of pieces of user data divided by the division circuitry such that each of the plurality of pieces of user data is included in each of the plurality of frequency channels;
• and
• a transmitter to transmits the plurality of pieces of user data distributed by the distribution processing circuitry for each of the plurality of frequency channels.
