MOBILE STATION APPARATUS, BASE STATION APPARATUS, HANDOFF METHOD, AND MOBILE COMMUNICATION SYSTEM

摘要

A handover procedure is easily performed in a carrier aggregation state of receiving a plurality of frequency bands. There are provided a plurality of reception branches for performing a reception process for each frequency band, and a reception-signal processing control section 10 that performs control of switching a reception branch in operation to a reception branch which corresponds to the frequency band of a handover destination indicated by a handover command message that has been received from a base station apparatus and indicates a start of handover. Herein, handover is performed by stopping the reception branch that corresponds to the frequency band of a handover source indicated by the handover command message and operating the reception branch that corresponds to the frequency band of the handover destination indicated by the handover command message.
