Abstract

In a data transmission method, a first communications device receives flag information. When the flag information indicates that one piece of control information can be used for scheduling of a plurality of transport blocks, the first communications device obtains transport block allocation information that indicates the number of transport blocks scheduled by the control information and a bit state corresponding to each transport block. Alternatively, when the flag information indicates that one piece of control information can be used for scheduling of only one transport block, the first communications device obtains hybrid automatic repeat request (HARQ) process number information, where the HARQ process number information indicates an HARQ process number corresponding to the transport block scheduled by the control information. The first communications device sends data or receives data based on the information.
