Example Embodiment 80: A wireless access node of a radio access network (RAN) that communicates over a radio interface with a wireless node, the wireless access node comprising: processor circuitry configured to establish, with the wireless node, dual connectivity (DC) comprising a first connection and a second connection, the first connection being relayed by an Integrated Access and Backhaul (IAB) node, and; receiver circuitry configured to receive, on the second connection, a failure information message; wherein the failure information message is based on a notification message that the wireless node receives from the IAB node, the notification message indicating a radio link failure (RLF) on the first connection, and; the failure information message comprises information representing the RLF.
Example Embodiment 81: The wireless access node of Example Embodiment 80, wherein the information representing the RLF comprises a type of failure, the type of failure indicating whether or not the transmission of the failure information message is caused by the notification message.
Example Embodiment 82: The wireless access node of Example Embodiment 80, wherein the notification message comprises information identifying a node on the first connection that detects the RLF, and the information representing the RLF comprises the information identifying the node.
Example Embodiment 83: The wireless access node of Example Embodiment 80, wherein the notification message comprises one or more measurement values of signal strength/quality, and the information representing the RLF comprises the one or more measurement values.
