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.

Abstract: For vehicle-to-everything (V2X) communication, an eNodeB (eNB) receives authorization information for a pedestrian UE which indicates whether a user equipment (UE) is authorized as the pedestrian UE. Upon receiving the authorization information for the pedestrian UE, the eNB may authorize the UE as the pedestrian UE or not according to the received authorization information, and decide a resource allocation mode for the authorized pedestrian UE.
