Abstract: The present disclosure relates to data transmission methods and apparatus. In one example method, a first terminal device receives downlink control information (DCI) from a network device, where the DCI is used to schedule uplink transmission or sidelink transmission, and the DCI indicates data transmission of the first terminal device or the first terminal device to assist in forwarding data of a second terminal device. The first terminal device performs the uplink transmission or the sidelink transmission based on the DCI.
