Abstract: The present invention provides a data transmission method, a device, and a system, and relates to the field of communications technologies, to resolve a problem that a base station cannot well identify specific remote UE from which data sent by relay UE comes. The method may include: receiving, by relay UE, data of remote UE, where the data includes a first identifier of the remote UE; determining, by the relay UE, a second identifier of the remote UE based on the first identifier; and sending the data of the remote UE and the second identifier of the remote UE to a base station.

Abstract: This application discloses a path switching method that includes: sending, by a first terminal, a first message to a first network device, where the first message is used to request to switch a second terminal from an indirect connection path for communicating with the first network device by using the first terminal to a direct connection path for communicating with the first network device or a second network device, or the first message is used to request to release a link between the first terminal and the second terminal, and the first network device is different from the second network device; and releasing, by the first terminal, the link between the first terminal and the second terminal. With this solution, a relay terminal can trigger switching of a remote terminal from an indirect connection path to a direct connection path, to adapt to a relay scenario more flexibly.

Abstract: Embodiments of the present disclosure provide timing advance (TA) obtaining methods and apparatuses. One example method includes generating, by a base station, an indication message and sending the indication message to UE, and receiving, by the UE, the indication message sent by the base station. The UE can then obtain a TA of a second carrier based on the indication message, where the second carrier is a carrier not used to transmit a PUSCH. Although the second carrier is a carrier not used to transmit a PUSCH, the TA of the second carrier can still be obtained.
