1. A method comprising:
determining, by a wireless device, a quantity of listen-before-talk (LBT) failures for an active uplink bandwidth part (BWP) of a cell;
sending, based on the quantity satisfying a threshold, an uplink signal associated with an LBT failure recovery procedure for the active uplink BWP of the cell; and
cancelling the LBT failure recovery procedure based on at least one of:
receiving, by the wireless device and during the LBT failure recovery procedure, LBT failure recovery reconfiguration parameters for the cell;
receiving, by the wireless device and during the LBT failure recovery procedure, downlink information indicating BWP switching for the cell;
deactivating the cell during the LBT failure recovery procedure; or
receiving, by a medium access control (MAC) layer of the wireless device from a radio resource control (RRC) layer of the wireless device and during the LBT failure recovery procedure, a request to reset the MAC layer.
