Disclosed are a data transmission method, device and system, which relate to the field of communications, and can solve the problem in the prior art that an incomplete sub-frame cannot be modulated and coded to perform data transmission. The specific solution is as follows: a network device acquiring the number of PRBs occupied by first data borne by a first sub-frame, wherein the number of PRBs occupied by the first data borne by the first sub-frame is pre-configured, and can be determined by the network device or be determined by a user equipment; determining a first TBS according to the number of PRBs occupied by the first data borne by the first sub-frame; modulating and coding the first data borne by the first sub-frame and the first data borne by a second sub-frame according to the first TBS; and sending the first sub-frame and the second sub-frame to the user equipment. The present invention is used for data transmission. |
