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: A resource allocation method includes sending, by the first device, a first message to the second device, where the first message is used to request a sidelink resource for the first device to send data to a third device, and the first message includes first identification information of the third device. The method further includes receiving, by the first device, a second message sent by the second device, where the second message is used to indicate a target sidelink resource for the first device to send the data to the third device. The method further includes using, by the first device, the target sidelink resource to send the data to the third device.

Abstract: A control signaling processing method, a device, and a system relate to the field of communications technologies, to perform integrity protection on control signaling exchanged between a DU and UE in a CU-DU separated access network architecture. The method includes: determining, by a DU, integrity protection parameters and an integrity protection algorithm, where the integrity protection parameters and the integrity protection algorithm are used to perform integrity protection on a signaling radio bearer between the DU and UE; determining, by the DU, a message authentication code MAC-I based on the integrity protection parameters and the integrity protection algorithm; and receiving, by the DU, control signaling sent by an RRC layer of the DU, and sending, to the UE, the control signaling carrying the MAC-I.

Abstract: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.
