PROBLEM TO BE SOLVED: To provide a technique in which data communication having high reliability using folding data is performed effectively.SOLUTION: In a communication system having a first communication device and a second communication device, the first communication device transmits first data to the second communication device, and the second communication device transmits third data in which second data is overlapped with the first data received from the first communication device, to the first communication device. The first communication device uses the first data stored by the first communication device and acquires the second data from the third data received from the second communication device.SELECTED DRAWING: Figure 2 |
