Abstract

In order to avoid interference efficiently and control the amount of radio resources that are not used for interference avoidance, the present invention provides a radio base station connected to a neighbor radio base station via inter-radio base station interface. The radio base station has: a radio communication section that performs radio communication with a user terminal using a UL/DL configuration indicating a configuration of uplink and downlink subframes in a radio frame; an interference detecting section that measures and detects interference that the radio base station suffers from; and a selecting section that uses an interference detection result as a basis to determine which to apply to each subframe, between a resource allocation-unrestricted scheme and an inter-cell uplink/downlink orthogonalization scheme.
