說明書
Example Embodiment 45: A method for a wireless node that communicates over a radio interface with a wireless access node of a radio access network (RAN), the method comprising: receiving from the wireless access node at least one reconfiguration message, the reconfiguration message activating a first data path and a second data path, the first data path and the second data path being established between the wireless access node and the wireless node, the second data path being relayed by a wireless relay node, and; receiving from the wireless relay node a notification message indicating a radio link failure (RLF) on the second data path; generating a failure information message; transmitting the failure information message to the wireless access node using the first data path; wherein the failure information message is based on the notification message and indicates the RLF occurring on the second data path.
Example Embodiment 46: The method of Example Embodiment 45, wherein the failure information message includes a type of failure indicating whether or not the transmission of the failure information message is caused by the notification message.
Example Embodiment 47: The method of Example Embodiment 45, wherein the notification message includes location information identifying a node on the second data path that detect the RLF, and the failure information message includes the location information.
Example Embodiment 48: The method of Example Embodiment 45, wherein the notification message includes one or more measurement values of signal strength/quality, and the failure information message includes the one or more measurement values.
