Abstract
In a wireless communication system, when data communication is performed between a relay device and a terminal (in a second path), the same amount of data is required to be transferred between a base station and the relay device (in a third path). An amount of wireless communication resources required is obtained by adding an amount inversely proportional to a capacity of each of the second and third wireless transmission-paths. Therefore, the amount inversely proportional to the capacity of the third path is consumed in excess. Based on a channel quality of a first wireless channel between the base station and the terminal, a channel quality of a second wireless channel between the terminal and the relay station, and a channel quality of a third wireless channel between the base station and the relay station, it is determined whether data communication between the base station and the terminal is relayed.
