Abstract:
A method of operation of a wireless communication device to perform handover from a source cell to a target cell in a wireless communication system is provided. The wireless communication device performs (202) a beam tracking procedure for one or more neighbor cells to provide, for each neighbor cell, a list of tracked beams for the neighbor cell. The wireless communication device receives (212) a handover command from a source radio access node that instructs the wireless communication device to perform a handover from a source cell served by the source radio access node to a target cell served by a target radio access node. The target cell is one of the one or more neighbor cells for which the beam tracking procedure is performed. The wireless communication device then selects (214) a beam of the target cell from the list of tracked beams for the target cell based on random access resource configuration and/or a quality threshold. The wireless communication device then performs (216) random access on the selected beam.
