Abstract:
A wireless device may perform a listen-before transmit (LBT) procedure for an uplink transmission. An LBT failure recovery procedure may be initiated based on a failure of one or more LBT procedures. The LBT failure recovery procedure may be aborted and/or canceled based on one or more conditions, such as receiving configuration (or reconfiguration) parameters, receiving an indication of a bandwidth part switching, deactivating a cell, and/or receiving a request to set (or reset) a communication layer of the wireless device.
