Abstract: A data transmission method includes determining, by a terminal device, to use a multi-path transmission mode for transmission of a first data flow. The multi-path transmission mode is through at least two paths. The data transmission method further includes performing, by the terminal device, transmission of the first data flow through at least two paths of a second path set. The second path set includes a direct network communication path on which the terminal device is configured to access a network and an indirect network communication path on which the terminal device is configured to access the network through a relay terminal device.

Abstract: Example communication methods apparatus are described. One example method includes receiving air interface link signal information of neighboring network devices by a source network device from a terminal device. The source network device determines a target network device based on sidelink information of the terminal device and the air interface link signal information of the neighboring network devices. Then, the source network device may send a handover request to the target network device, so that the terminal device can be handed over from the source network device to the target network device. Therefore, the target network device determined by the source network device can better meet an air interface link communication requirement and a sidelink communication requirement of the terminal device.

Abstract: The present disclosure relates to communication methods and apparatus. In one example method, a first message from a relay terminal is received by a first terminal. The first message includes first indication information, an application layer identifier of a second terminal, and a first address of the second terminal. The first indication information can indicate a first unicast link between the first terminal and the relay terminal. The first terminal updates first information of the first unicast link based on the first message to obtain updated second information of the first unicast link. The second information includes the application layer identifier of the second terminal and the first address.
