An apparatus may receive a physical downlink control channel (PDCCH) order from a source cell. The PDCCH order indicates a candidate cell for a physical random access channel (PRACH) transmission before a cell switch command. Then, the apparatus may transmit a PRACH preamble to the candidate cell responsive to the PDCCH order. Also, the apparatus may determine not to receive a random access response (RAR) from the source cell based on the PDCCH order.
