WIRELESS BASE STATION, USER TERMINAL, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed to reduce the impact of interference and furthermore improve the efficiency of the use of radio resources even when different DL/UL configurations are employed between neighboring transmitting/receiving points. A radio base station that can communicate with user terminals via time division duplex and that can furthermore 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.
