MOBILE COMMUNICATION SYSTEM, BASE STATION, AND USER TERMINAL

摘要

In a mobile communication system that employs a FDD scheme, a HeNB (100-1) and a UE (200-1) use a pair of a UL CC and a DL CC for radio communication. The HeNB (100-1) and the UE (200-1) change the UL CC of the pair of the UL CC and the DL CC to another CC while maintaining the DL CC during execution of the radio communication.

1. A user terminal in a mobile communication system that performs radio communication in which a plurality of component carriers is configured, comprising:
a receiver configured to receive, when the user terminal is performing radio communication in a condition that a first component carrier and a second component carrier are configured, information on changing of the first component carrier, from a base station, and a controller configured to control, in response to reception of the information, so as to change the first component carrier, wherein the controller executes control related to changing of the first component carrier without performing reconnection.
