In some examples, the first cell may send a physical downlink control channel (PDCCH) order that triggers the UE to transmit a physical random access channel (PRACH) message to a candidate cell. In some examples, the first cell may send to the UE an indication specifies that the UE is to transmit only the PRACH message in response the PDCCH order. In some examples, the first cell sends at least one transmission parameter to the UE after the UE transmits the PRACH message to the second cell.
