Abstract: A vehicle driving authority transfer method and apparatus are described for assisted driving and automated driving. The method includes checking a status of a system of a vehicle before a driving authority of the vehicle is transferred. The driving authority of the vehicle is transferred only when the vehicle is at a normal status. Therefore, the status of the system of the vehicle is checked before transferring the driving authority of the intelligent vehicle, thereby avoiding a liability dispute arising from a traffic accident caused by abnormality of the status of the system of the vehicle, especially by abnormality of a braking system and/or a steering system closely related to vehicle operability/manipulability, after the driving authority of the vehicle is transferred.

Abstract: Example multi-carrier based transmission methods and apparatus are described. One example method includes that a first terminal device obtains first direct link data. The first terminal device sends the first direct link data and first indication information to a second terminal device on a first transmission carrier, where the first indication information is used to indicate that the first terminal device sends second direct link data on at least one second transmission carrier. The second terminal device adjusts a receive link according to the indication information and receives the second direct link data on the second transmission carrier.

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.
