Abstract:
A base station 1 includes a radio communication unit 11 and a frequency channel control unit 15. The radio communication unit 11 is capable of forming a primary cell and a secondary cell, and transmitting a physical channel for data transmission (HS-PDSCH) in each of these two cells. Further, the frequency channel control unit 15 determines a frequency channel available to the secondary cell based on the load status of a nearby cell formed by a nearby base station 7. In this way, the interference to the nearby cell caused by the base station 1 is suppressed.
