摘要： A station acquires, when one or a plurality of base stations transmit a signal addressed to a plurality of mobile stations by using the same radio resource, a first dedicated pilot signal allocated to the mobile station and a second dedicated pilot signal allocated to another mobile station. The mobile station receives a radio signal from the base station that is connected to the mobile station. By using the second dedicated pilot signal, the station estimates a channel through which the radio signal transmitted from the base station connected to the other mobile station reaches the mobile station. When the mobile station decodes a data signal addressed to the mobile station from the received radio signal by using the first dedicated pilot signal allocated to the mobile station, the mobile station suppresses an interference signal in the radio signal by using the estimate information.
