1. A method performed by a wireless device for handover, the method comprising:
receiving an RRC connection reconfiguration message from a source gNB, the RRC connection reconfiguration message comprising configuration information for a plurality of beams, the configuration information comprising common random access configuration information associated with one or more beams of a target cell and dedicated random access configuration information associated with one or more beams of the target cell, wherein the target cell is different than a source cell, the source cell is associated with the source gNB;
selecting a beam associated with the target cell based on the configuration information for the plurality of beams, the selected beam to be used in a handover to the target cell;
accessing the target cell using the selected beam; and
transmitting a confirmation message to the target network node indicating that the handover has been completed.
