Abstract
一种数据传输方法及装置，其中方法包括：终端设备向第一网络设备发送消息1，消息1包括随机接入前导码；终端设备接收来自第一网络设备的DCI以及所述DCI所调度的消息2；消息2中包括下行数据，所述DCI和/或所述消息2包括第一信息，所述第一信息用于调度所述消息2的ACK/NACK反馈信息；所述终端设备根据所述第一信息向所述第一网络设备发送所述ACK/NACK反馈信息。通过上面的方法，第一信息用于调度ACK/NACK反馈信息，因此终端设备可以根据DCI和/或消息2中包括的第一信息，在MT‑EDT场景下，向第一网络设备发送消息2的ACK/NACK反馈信息，可以提高消息2中的下行数据传输的鲁棒性。
