1. A wireless communication system comprising a base station device, a mobile communication terminal, and a relay station device, the relay station device relaying data transmission between the base station device and the mobile communication terminal, wherein
a first transmission path is used to perform a first wireless communication between the base station device and the mobile communication terminal using a first carrier that is a first component carrier, a second transmission path is used to perform a second wireless communication between the base station device and the mobile communication terminal using a second carrier that is a second component carrier, the second carrier having a frequency different from that of the first carrier, and a third transmission path is used to perform a third wireless communication, going through the relay station device, between the base station device and the mobile communication terminal, the third wireless communication being performed by performing a fourth wireless communication between the base station device and the relay station device using the first carrier and also by performing a fifth wireless communication between the relay station device and the mobile communication terminal using a third carrier, wherein at least two of the first, second and third transmission paths can be used, and wherein the base station device comprises: an information collection unit configured to collect first information for calculating evaluation values for each of the first, second, and third transmission paths; an evaluation value calculation unit configured to calculate the evaluation values for each of the first, second, and third transmission paths, the calculation being performed based on the collected first information; and a transmission path selection unit configured to select, using the evaluation values of each of the first, second, and third transmission paths, a fourth transmission path to be used by the mobile communication terminal. |
