FAILURE INFORMATION FOR WIRELESS RELAY NETWORKS

Document Type and Number:

WIPO Patent Application WO/2020/222309

Kind Code:

A1

Abstract:

A wireless node that communicates over a radio interface with a wireless access node of a radio access network (RAN), the wireless node comprising: processor circuitry configured to establish, with the radio access 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; receiver circuitry configured to receive from the IAB node a notification message indicating a radio link failure (RLF) on the first connection, and; transmitter circuitry configured to transmit, based on the notification message, a failure information message to the wireless access node using the second connection, wherein; the failure information message comprises information representing the RLF.
