Abstract

To avoid occurrence of communication conflict at the transmission time of re-transmission data without losing real-time performance of data transmission with respect to data missing during communication, thereby enabling excellent data transmission a reception controller allocates time slots for transmission of second data (re-transmission) transmitted from transmitters on the basis of a re-transmission request message according to a reception condition of first data (latest data) and the reception controller transmits an acknowledgement message (ACK) for the first data with a slot time being embedded in an acknowledgement message for every reception-success transmitter.
