Title:
COMMUNICATION METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/088638
Kind Code:
A1
Abstract:
The present application relates to a communication method and apparatus, and a device. When camping on a second network device, a second terminal device receives a first message, the first message being used for instructing the second terminal device to camp to a first network device, and the first network device and the second network device corresponding to different PLMNs. The second terminal device camps to the first network device. In the embodiments of the present application, two terminal devices that camp on the network devices corresponding to different PLMNs can be changed to camp on the same network device, and thus, if the two terminal devices communicate by means of sidelink, mechanisms such as HARQ can be normally implemented, thereby improving the reliability of information transmission between terminal devices.
