Abstract:
A method performed by a UE for Listen Before Talk (LBT) failure detection and recovery includes the UE triggering a first consistent LBT failure procedure for a first consistent LBT failure detected on a first Bandwidth Part (BWP) of a first cell of a Base Station (BS); triggering a second consistent LBT failure procedure for a second consistent LBT failure detected on a second BWP of a second cell of the BS; triggering a first Scheduling Request (SR) procedure for the first consistent LBT failure; triggering a second SR procedure for the second consistent LBT failure; receiving, from the BS, an indication for BWP switching of the first cell; switching an active BWP of the first cell based on the indication; canceling the first consistent LBT failure procedure in response to receiving the indication; and canceling the first SR procedure in response to receiving the indication.
