Abstract: A method and apparatus for supporting a fast link recovery and link status reporting in a wireless communication system is provided. When a node detects a radio link problem on a wireless backhaul link between integrated access and backhaul (IAB) nodes from the node to a donor node of an TAB network, the node reselects a cell operated by a gNB which is directly connected to the donor node, and performs a random access procedure towards the cell operated by the gNB to report information on the radio link problem to the cell. The donor node may establish a new path for the node.

Abstract: A method and apparatus for performing an inter-master eNodeB (MeNB) handover procedure without secondary eNB (SeNB) change in a wireless communication system is provided. A target MeNB decides to keep bearers of a SeNB, and transmits a handover request acknowledge message including a first indication of keeping the bearers of the SeNB to a source MeNB. The first indication may indicate that a user equipment (UE) context in the SeNB is kept. Upon receiving the handover request acknowledge message including the first indication, the source MeNB transmits a SeNB release request message including a second indication of keeping the bearers of the SeNB to the SeNB. The second indication may indicate that a UE context in the SeNB is kept.
