Abstract
A radio base station capable of reducing the impact of interference and improving the efficiency of the use of radio resources even when different DL/UL configurations are employed between neighboring transmitting/receiving points is disclosed. The radio base station can communicate with user terminals via time division duplex and is able to change and control DL/UL configurations, has a subframe type determining section that classifies subframes into fixed subframes or flexible subframes, in accordance with the relationship between the DL/UL configurations that are employed in the radio base station and the DL/UL configurations that are employed in other radio base stations, and a frequency allocation control section that applies mutually different frequency allocation methods to the fixed subframes and the flexible subframes.
