摘要： In a message-transmitting station, a signal to be transferred is divided into a plurality of time slots, an error correcting/detecting code is added to each time slot, and a re-transmission sequence order number in unit of messages, a re-transmission number and an address designating ID of a terminal device are added to a specified time slot. Then, data of the time slots are transmitted from the message-transmitting station to a message-receiving station. In the message-receiving station, it is determined whether or not any order number is missing, by demodulating and decoding the data unit containing the re-transmission sequence order number and the address, and a re-transmission request signal is transferred in accordance with the result of the comparison between the sequence number included in the demodulated, decoded data unit and the sequence number received last as an indication of the condition in which the data in each data unit has reached the message-receiving station. Further, at least one of any specified and all of the time slots are re-transmitted from the message-transmitting station in accordance with the re-transmission request signal supplied from the message-receiving station.
