Abstract

The application provides a data transmission method and a data transmission device, advantageous in improving data transmission efficiency. The method comprises: a first device transmits indication information to a second device, wherein the indication information indicates a first transmitting method for a first transmission block, and the first transmitting method is one of at least two transmitting methods; and the first device transmits the first transmission block according to the first transmitting method, or the first device receives the first transmission block according to the first transmitting method.

Description

technical field [0001] This application relates to the field of communications, and more particularly, to methods and devices for transmitting data Background technique [0002] In the current technology, the sending end and the receiving end receive or send the transport block in a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) transmission mode by default. Specifically, after the sending end sends the transport block, it waits for feedback information sent by the receiving end to indicate whether the transport block is received correctly. Then, according to the feedback information, it is determined whether to perform Hybrid Automatic Repeat reQuest (HARQ) retransmission on the transport block. However, with the growth of mobile data traffic, the connection of massive mobile communication devices, and the emergence of various new services and application scenarios, the default HARQ transmission method for transmitting transmission blocks is not co...
