摘要: The present application relates to the technical field of wireless communications and provides an information transmission method and a device thereof. In the present application, a source IAB donor centralized unit (CU) of an IAB node receives first candidate cell identifiers from the IAB node or first candidate cell identifiers from a target IAB donor CU of the IAB node, the first candidate cell identifiers being allocated for the IAB node migrating to the target IAB donor CU, and the first candidate cell identifiers comprising candidate cell identifiers of a sub node of the IAB node and/or a terminal connected to the IAB node; and the source IAB donor CU sends a second candidate cell identifier to the sub node of the IAB node and/or the terminal connected to the IAB node, the second candidate cell identifier comprising at least one of the first candidate cell identifiers.

摘要: The present disclosure provides a path fallback method and apparatus, and a storage medium. The method includes: determining to migrate F1 of an edge IAB node from a target path to a first path, where the first path is a source path or an else path, the source path being a path used by F1 of the edge IAB node before using the target path, and the else path being a path other than the target path and the source path; and transmitting indication information to a target IAB donor and/or the edge IAB node, the indication information being used to give an indication to release or suspend configuration information for transmitting, on the target path, all or part of F 1 of the edge IAB node. The method realizes a path fallback for F1 of the edge IAB node which has been migrated to the target path.

摘要: An information transmission method and an information transmission device in IAB node group switching, and a network device are provided. The method includes receiving first information transmitted by a source CU, the source CU being a CU for a donor in a source path for a migrating node. The first information includes at least one of topological information or context information, the topological information includes a connection relationship between the migrating node and a descendant node of the migrating node, the context information includes at least one of node context information or context information of a UE, the node context information includes at least one of context information of the migrating node or context information of the descendant node of the migrating node, and the UE includes at least one of a UE connected to the migrating node or a UE connected to the descendant node of the migrating node. According to the present disclosure, it is able to simplify a signaling process for switching the IAB node between the CUs to some extent.
