More Information
Summary:Embodiments of the present invention provide a data transmission method. The method includes: obtaining, by a sending device, a first transport block size TBS, where a bit rate corresponding to the first TBS is greater than or equal to 1; obtaining, by the sending device, a second TBS from a pre-defined TBS set based on the first TBS; and obtaining, by the sending device, data in at least two different locations in a same code block based on the second TBS, and sending the data to a receiving device for the receiving device to perform hybrid automatic repeat request HARQ combining and decoding on the data in the at least two different locations. The embodiments of the present invention further provide a data transmission apparatus. The embodiments of the present invention specifically have advantages of improving data transmission efficiency and spectrum efficiency of a data link.
