Disclosed are a communication system, a communication device, a communication method, and a program all for preventing disconnection of communication during re-transmission in response to an automatic repeat request in a confirmation mode. The communication system is provided with a first communication device including data transmitting means and data re-transmitting means and a second communication device connected to the first communication device and including data receiving means for receiving data transmitted from the first communication device and data re-transmission requesting means for requesting re-transmission of data not normally received by the data receiving means. The data receiving means determines whether or not the re-transmission data requested by the data re-transmission requesting means will be re-transmitted from the first communication device.
