Data transmission method, communication device, and data transmission system

Abstract

A data transmission method, a communication device, and a data transmission system are disclosed. The method includes: determining to-be-transmitted data that needs to be sent to a network side device; before an initial transmission moment of transmitting the to-be-transmitted data to the network side device arrives, sending the to-be-transmitted data to a coordinating device; receiving the to-be-transmitted data sent by the target device; obtaining transmission parameter information; and when the initial transmission moment corresponding to the to-be-transmitted data arrives, sending the received to-be-transmitted data to the network side device based on the transmission parameter information. Therefore, when the target device needs to send the to-be-transmitted data to the network side device, the coordinating device may help the target device perform initial transmission of the to-be-transmitted data, thereby increasing a success probability of initial transmission, and further improving link reliability.
