Abstract

Provided is a method for performing a handover from a first base station to a second base station by a user equipment that is performing a radio communication over a communication channel formed by aggregating a plurality of component carriers. The method includes a step of transmitting a handover command for a component carrier for which a handover has been approved by the second base station among the plurality of component carriers from the first base station to the 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.
