1. A method performed by a wireless device configured for use in a wireless communication network, the method comprising:
obtaining a configuration that governs how the wireless device is to monitor for or attempt to recover from consistent uplink listen-before-talk (LBT) failure that occurs during a mobility procedure triggered by the wireless device; and
according to the obtained configuration, monitoring for or attempting to recover from consistent uplink LBT failure occurring during the mobility procedure, wherein obtaining the configuration comprises receiving, from a network node, signaling indicating at least a part of the configuration, and wherein the signaling is received while the wireless device is in Radio Resource Control (RRC) connected mode.
