Abstract: The present disclosure provides a data sending method. A first terminal device, determines at least two carriers to transmit at least two pieces of data corresponding to a same transport block, and in a one-to-one correspondence with the at least two pieces of data. The at least two pieces of data can be sent by the first terminal to a second terminal device or a network device by using the at least two carriers. When the first terminal device sends data, the first terminal device may send the at least two pieces of data to the second terminal device or the network device on the at least two carriers to improve reliability of data transmission. The at least two pieces of data may be sent simultaneously, to avoid an increased latency by transmissions of the at least two pieces of data in different time units.
