METHOD OF PERFORMING HANDOVER, USER EQUIPMENT, BASE STATION AND RADIO COMMUNICATION SYSTEM

摘要

FIELD: radio engineering, communication.SUBSTANCE: invention relates to mobile communication. The method includes a step of transmitting a handover command for each component carrier for which handover has been approved by a second base station among the plurality of component carriers from a first base station to user equipment and a step of trying to make an access from the user equipment to the second base station for each component carrier in response to the handover command.EFFECT: providing handover from the first base station to the second base station through user equipment which performs radio communication over a link formed by aggregation of multiple component carriers.10 cl, 15 dwg
