1. A method performed by a wireless device, the method comprising:
receiving, from a radio network node, a control message indicating a conditional handover configuration that contains a handover configuration and one or more trigger conditions whose fulfillment is to trigger execution of the handover configuration by the wireless device, wherein the control message includes configuration-specific information that distinguishes the conditional handover configuration from one or more other conditional handover configurations that are configurable for a link, wherein the configuration-specific information includes a radio network temporary identifier (RNTI) and/or a random access channel configuration that are unique at least among any conditional handover configurations configured for the link; and
based on fulfillment of the one or more trigger conditions, applying the handover configuration by transmitting a control message of a random access procedure to a radio network node, the control message of the random access procedure including the RNTI and/or being transmitted according to the random access channel configuration.
