Abstract: Provided is a data transmission method and a data transmission apparatus. The method includes: obtaining measurement results of channel transmission qualities of multiple channels, where a data duplication transmission function is configured on the multiple channels and is used for indicating an establishment of multiple connections with a terminal on the multiple channels, and the multiple connections are used for simultaneous transmissions of duplicated data on the multiple channels; determining, according to the obtained measurement results, whether to activate the data duplication transmission function; and performing a data transmission with the terminal on the multiple channels according to a determination result. A problem, in relevant technology, that the transmission resource consumption is large when the data transmission is performed in the manner of duplication transmission is solved, and the effects of improving link transmission quality and reducing transmission resource consumption are achieved.
