It is sought to permit communication distance increase, interference power reduction and hardware scale increase suppression. It is made possible to increase the communication distance by selecting sub-carriers according to the line quality. In the case of the multiple cell construction, by selecting sub-carriers according to the line capacity it is made possible to reduce the interference power and realize communication, in which all cells use the same frequency band. In this case, it is possible to suppress hardware scale increase that is the case in the prior art techniques.
