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.

Dependent claims

A data transmission method, comprising:

obtaining measurement results of channel transmission qualities of a plurality of channels, wherein a data duplication transmission function is configured on the plurality of channels and is used for indicating an establishment of a plurality of connections with a terminal on the plurality of channels, and the plurality of connections are used for simultaneous transmissions of duplicated data on the plurality of 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 plurality of channels according to a determination result,
wherein determining, according to the obtained measurement results, whether to activate the data duplication transmission function comprises:
in a case that the measurement results indicate that the channel transmission qualities of all of the plurality of channels meet a preset condition, determining to activate the data duplication transmission function;
and
in a case that the measurement results indicate that the channel transmission quality of at least one of the plurality of channels does not meet the preset condition, determining not to activate the data duplication transmission function;
wherein the preset condition comprises a condition where the channel transmission quality is higher than a first preset threshold and lower than a second preset threshold, the second preset threshold being greater than the first preset threshold.
