Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/217520
Kind Code:
A1
Abstract:
The present application provides a data transmission method and device, and relates to the technical field of communications. The technical solution aims to enable data frames needing to be synchronously transmitted to quickly complete delay alignment in the transmission process so as to ensure synchronous transmission of the data frames. The method comprises: a source node transmitting a first data frame to a first node by means of a first transmission channel, and transmitting a second data frame to the first node by means of a second transmission channel, wherein the first node is a downstream node of the source node, the first data frame comprises a first identifier, the second data frame comprises a second identifier, and the first identifier corresponds to the second identifier and is used for instructing the first node to perform delay alignment on the first data frame and the second data frame.
