Abstract:
Apparatuses, methods, and systems are disclosed for handling consistent UL LBT failure. One apparatus (500) includes a transceiver (525) that communicates with a serving cell in a wireless communication network. The apparatus (500) includes a processor (505) that detects (705) an uplink LBT failure in an active BWP of the serving cell and determines (710) a state of consistent uplink LBT failure for the active BWP in response to detecting a predetermined number of uplink LBT failures. The processor (505) sets (715) an unexpired timing alignment timer as expired in response to determining the state of consistent uplink LBT failure for the active BWP and initiates (720) a random-access procedure for the serving cell.
