Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/083371
Kind Code:
A1
Abstract:
A data transmission method and device, relating to the field of communication technology. Said method comprises: a data sending end acquiring tail data of target data, and encoding the tail data to obtain backup data, the backup data being used for recovering a part of the tail data that is lost; and the data sending end sending the tail data and the backup data to a data receiving end. The data receiving end receives the tail data and the backup data, and when it is determined that data loss occurs in the tail data, recovers the lost tail data according to the backup data. According to said method, tail data of target data is encoded and protected, and backup data of the tail data is obtained at the same time, so that in a data transmission process, when tail data loss occurs, recovery can be performed by means of the backup data, so that a data receiving end can receive sufficient ACK information, so as to reduce a time delay of retransmitting the tail data generated due to the tail data loss, so that the transmission efficiency of the entire data can be improved.
