Abstract: A method performed by a remote User Equipment (UE) for handling a path switch failure of a connection in a wireless communications network. The remote UE detects the path switch failure. The path switch failure relates to a failure to switch path from a first path to a first network node, to a second path to a second network node. At least one path out of the first path and the second path comprises an indirect link. Upon detecting the path switch failure, the remote UE continues to apply a previous configuration for the connection that was used before the path switch was triggered. During continuing to apply the previous configuration, to recover from the path switch failure, the remote UE triggers a recovery procedure to continue the transmission. During the recovery procedure, the connection for the first path is kept.
