1. A method of wireless communication performed by an apparatus of a user equipment (UE), comprising:
transmitting an indication associated with the UE supporting a dual active protocol stack (DAPS) handover from a source cell or source master cell group (MCG) to a target cell or target MCG to the source cell;
transmitting on a normal uplink (NUL) to the source cell or source MCG in an active bandwidth part (BWP) for a NUL carrier;
transmitting on a supplementary uplink (SUL) to the source cell or source MCG in an active BWP for a SUL carrier; and
establishing, in association with the DAPS handover being triggered, an active uplink BWP on the target cell or target MCG that is within one or more of the active BWP for the SUL carrier or the active BWP for the NUL carrier.
