Abstract
In a relay transmission method and system, and a device used therefor, efficiently realizing relay transmission on a half-duplex transmission path while controlling retransmission, a transmitter on the transmission side receives a polling from a transmitter on the reception side, and then transmits a frame-numbered data frame to a relay transmitter. If a data frame is not normally received, the transmitter on the reception side generates a retransmission request asking for retransmission thereof, and outputs the request for the relay transmitter. If storing the requested data frame in its retransmission frame buffer, the relay transmitter deletes the data frame's frame number from the retransmission request, and then transfer the request. Thereafter, the relay transmitter adds, to the retransmitted data frame, the data frame whose frame number has been deleted during last transfer.
