Title:
RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD, MOBILE STATION DEVICE AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/007351
Kind Code:
A1
Abstract:
Provided is a radio communication system which is provided with a plurality of base station devices and a mobile station device that communicates with the plurality of base station devices. The radio communication system achieves excellent transmission speed by the mobile station device being provided with: a necessity/unnecessity determination unit which determines the necessity or unnecessity of carrier aggregation with reference to the state of communication with a first base station device that is a base station device being communicating with the mobile station device among the plurality of base station devices, a cell search unit which, when the necessity/unnecessity determination unit determines that the carrier aggregation is necessary, searches for a communicable base station device; and a carrier aggregation request unit which, when the communicable base station device is detected by the search, notifies the first base station of a request for the carrier aggregation.
