Title:
COMMUNICATION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/068094
Kind Code:
A1
Abstract:
Embodiments of the present application provide a communication method and a related device. The method comprises: when a first node determines that a radio link failure (RLF) occurs in a radio link between the first node and a second node and that no other available path is present between the first node and a destination node, the first node sending first indication information to a third node. The first indication information is used for indicating the RLF or an attempt to perform link recovery. The second node is a parent node of the first node, and the third node is a child node of the first node, or, the second node is a child node of the first node, and the third node is a parent node of the first node or a host node connected to the first node. By means of this method, a rerouting function of a relay node can be fully used, the stability of data relay is improved, and unnecessary link resource waste and air interface signaling overhead are avoided.
