Abstract: A second device sends a first message to a first device to request the first device to establish a unicast connection to the second device. The first message carries a medium access control (MAC) address, an address identifier, and a security mechanism of the second device. The first device determines, based on the first message, that establishment of the unicast connection between the first device and the second device is abnormal, and sends a second message to the second device. The second message carries the MAC address, the address identifier, and an error identifier of the second device, so that the second device performs corresponding handling based on a reason why establishment of the unicast connection is abnormal that is indicated by the error identifier.

Abstract: This application provides a data transmission method and apparatus. The method includes: obtaining, by a terminal, information used to indicate a first condition; obtaining to-be-transmitted data; and when the first condition is met, sending, by the terminal over a sidelink, the to-be-transmitted data that is on a first logical channel by using a first carrier frequency and the to-be-transmitted data that is on a second logical channel by using a second carrier frequency. In this method, the same data is sent, over the sidelink, on different carrier frequencies by using two logical channels, and a receiving device can receive the same duplicate data, thereby improving data transmission reliability.
