A retransmission control method of the present invention includes the steps in which a receiving terminal: measures a round trip time (RTT) between the receiving terminal and a sending terminal; calculates an RTO by using the measured RTT; and starts a time counting operation of the RTO upon reception from a point in time when a segment is received from the sending terminal; transmits a segment prompt signal which prompts the sending terminal to transmit a segment, when the segment is not received from the sending terminal until the RTO is completed, and in which the sending terminal: retransmits a segment to the receiving terminal when there is a segment to be retransmitted; and transmits a data-less signal to the receiving terminal when there is a segment that should be retransmitted, the data-less signal indicating that there is no segment that should be retransmitted.
