Abstract: This application provides a direct link data transmission method, a terminal device, and a network device. The method includes: receiving, by a first terminal device, first configuration information sent by a network device, where the first configuration information includes information about a transmission resource set, and the transmission resource set is a transmission resource set shared between a second terminal device that uses a centralized scheduling transmission mode and a third terminal device that uses a distributed transmission mode; detecting, by the first terminal device, a load level of a resource unit in the transmission resource set based on the information about the transmission resource set; and sending, by the first terminal device, report information to the network device based on the load level, where the report information includes information about an occupied resource unit and/or information about an available resource unit in the transmission resource set. A transmission resource allocated to the first terminal device can be prevented from colliding with a transmission resource of another terminal device, so that communication quality of a terminal device and user experience is improved.

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.

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.
