摘要： This application provide a retransmission control method, a communications interface, and an electronic device. When a transmit end transmits a first data packet to a receive end and does not receive an acknowledgement corresponding to the first data packet within a first RTO, the transmit end retransmits a second data packet based on a second RTO. The second data packet is a data packet transmitted by the transmit end after the transmit end transmits the first data packet. The second RTO is related to a receive timestamp of the acknowledgement corresponding to the first data packet and a transmit timestamp of the first data packet.
