摘要：
A wireless base station apparatus includes an interference report receiver configured to receive interference reports transmitted on a shared radio resource from a plurality of wireless terminals that are present in a plurality of adjacent cells that are adjacent to a target cell, the shared radio resource being comprised of a plurality of carriers and being shared between the plurality of adjacent cells, and an adaptive fractional frequency reuse controller configured to control adaptive fractional frequency reuse processing in a downlink of the target cell, based on the received interference reports showing a downlink reception quality, wherein the interference reports are transmitted using selected carriers from the plurality of carriers by the plurality of wireless terminals, based on the downlink reception quality.
