Abstract: The present application relates to the 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 including candidate cell identifiers of a sub node of the JAB 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 including at least one of the first candidate cell identifiers.

Abstract: 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.

Abstract: An antibacterial leather uses the organic silica gel as the main component, uses the carboxymethyl chitosan silver as the antibacterial factor, and uses the modified nano-silica and the modified layered double oxide as the flame retardant factor. The synergistic effects between the components, such as the good binding between carboxymethyl chitosan silver and the substrate, the synergistic flame retardant effect between flame retardant factors, the bonding effect between modified nano-silica and dimethicone, and the synergistic effect between the high-viscosity dimethicone and the low-viscosity dimethicone are utilized to improve the process, thereby obtaining a good antibacterial, flame retardant and other properties, meanwhile meeting the requirement for the material mechanical properties and environmental protection.
