Title:

DATA TRANSMISSION METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2023/024684

Kind Code:

A1

Abstract:

Provided in the present application are a data transmission method and apparatus. The method comprises: a first control entity determining, according to information for scheduling an air interface resource, a parameter for data transmission, and then sending, to a first execution entity, the parameter for data transmission; and the first execution entity performing redundant transmission on data according to the parameter for data transmission, wherein a receiver for the redundant transmission is a second execution entity. By means of the data transmission method and apparatus provided in the present application, when a service is damaged due to relatively poor air interface quality, the delay of retransmission can be reduced, and the success rate of redundant transmission is improved.
