Abstract
A base station device includes: a signal receiving unit to receive a downlink signal, which is transmitted from an adjacent base station over a downlink frequency band of a frame for the adjacent base station, over an uplink frequency band of a silent inverted frame during a first time interval, during which the base station device uses the silence inverted frame; a measuring unit to measure a channel environment with the adjacent base station based on the downlink signal from the adjacent base station; and an interference removing unit configured to remove the signal interference induced from the adjacent base station by removing the downlink signal received from the adjacent base station over a uplink frequency band of the base station device during a second time interval based on the channel environment with the adjacent base station.
