摘要： A control unit 130 assigns a first new call to a radio resource of a frequency channel with a small interference power and, when there is an available radio resource, assigns new calls after the first new call to radio resources of a frequency channel the same as, or adjacent to, the frequency channel of the radio resource of the first new call. The control unit 130, when there is no available radio resource, selects a combination of a multiplex call originator and a multiplex call receiver to which space division multiplexing may be carried out and, by calculating multiplexing priorities, selects a combination of a multiplex call originator and a multiplex call receiver having high priorities. Then, the control unit 130 generates an available radio resource by carrying out the space division multiplexing and assigns the new calls after the first new call to the generated radio resources.
