A UE receives configuration from a source cell for conditional handover for target cell(s). At least one of the target cell(s) also supports DAPS handover. The UE determines that either a RLF or HOF has occurred. The UE selects one of the target cell(s) for a handover, and performs a process for handover to the selected target cell. A UE receives individual handover commands and corresponding configuration for conditional handover for target cell(s) and an indication to use DAPS handover if possible in response to a handover. The UE determined condition(s) for handover to one of the target cell(s) have triggered, wherein the one target cell supports DAPS handover. The UE performs, based on the indication to use DAPS handover if possible in response to a handover, handover by the user equipment to the one target cell without releasing the source cell while accessing the one target cell.
