Title:
COMMUNICATION SYSTEM, MOBILE STATION DEVICE, WIRELESS LINK STATE MANAGEMENT METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/071037
Kind Code:
A1
Abstract:
Disclosed is communication system which includes a base station device which performs communication using multiple frequency bands, and a mobile station device wirelessly connected to the base station device. Taking into consideration the coordination relationship of the multiple bandwidths, the communication system implements efficient management of the wireless link states of the frequency bands. In the communication system, the base station device and the mobile station device aggregate multiple cells of different frequencies to perform communication. When multiple cells of different frequencies are determined for the aforementioned mobile terminal device, the aforementioned base station device configures for each of the aforementioned cells connection information showing the uplink and downlink coordination relationship, and sets timers in order to manage the states of the aforementioned cells. On the basis of the connection information of each of the aforementioned cells which was configured by the aforementioned base station device, the aforementioned mobile station device simultaneously changes the uplink and downlink states of the aforementioned cells when the aforementioned timers expire.
