1. A method for wireless communication, comprising:
updating configuration information for a downstream device of a migrating integrated access backhaul node (IAB-node) during an inter-donor migration from a source IAB-donor to a target IAB-donor by:
providing, by a source IAB-donor central unit (CU), updated configuration information into system information which is contained in a system information block (SIB) other than SIB1 carried in a SystemInformation (SI) message, and encoding the system information with the updated configuration information; and
sending, by the source IAB-donor CU, the system information including the updated configuration information as a radio resource control (RRC) container to a migrating IAB-node distributed unit (DU) via F1-AP, so that the migrating IAB-node DU forwards the system information including the updated configuration information through a dedicated RRC message to the downstream device.
