Abstract:
This disclosure provides systems, methods and apparatuses for a user equipment (UE) performing Listen Before Talk (LBT) procedures during a handover, such as during a dual active protocol stack (DAPS) handover or a conditional handover. During the handover, the UE may have a source connection with a source cell. If the source cell is unlicensed, the UE may perform LBT for a channel of the source cell. The UE may establish a target connection with a target cell before releasing the source connection with the source cell. If the target cell is unlicensed, the UE may perform LBT for a channel of the target cell.
