Title:
DATA PACKET TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/015833
Kind Code:
A1
Abstract:
The present invention provides a data packet transmission method and device. The method comprises: a sending end device performs channel coding on a data packet to be sent, and divides the coded data packet into at least two data sub-packets; allocate transmission resources for each data sub-packet; generate control information for each data sub-packet according to the transmission resources of the at least two data sub-packets, the control information for each data sub-packet being used for indicating transmission resources of the at least two data sub-packets of the data packet to which the data sub-packets belong; and send each data sub-packet and the control information of the data sub-packet on corresponding transmission resources. By transmitting a data packet and control information for indicating transmission resources of data sub-packets at the same time, a reception end device can identify multiple times of transmission of a same data packet and can perform joint processing on multiple data sub-packets corresponding the same data packet so as to obtain the data packet to be sent, thereby improving the reliability of data packet transmission.
