    • To reduce deterioration of a downlink signal when a multicarrier transmission is performed. A base station device eNB according to the present invention communication system includes: an uplink signal reception unit 17 configured to receive an uplink signal in a first carrier and an uplink signal in a second carrier, the uplink signal being transmitted from a user equipment UE; and a downlink signal transmission unit 15 configured to transmit a downlink signal in the first carrier and a downlink signal in the second carrier to the user equipment UE, wherein the downlink signal transmission unit 15 is configured to decide whether to transmit the downlink signal in the first carrier based on whether the uplink signal reception unit 17 receives the uplink signal in the second carrier.
    • 为了减少执行多载波传输时的下行链路信号的恶化。 根据本发明的通信系统的基站设备eNB包括:上行链路信号接收单元17,被配置为在第一载波中接收上行链路信号,并在第二载波中接收上行链路信号,所述上行链路信号从用户设备UE发送; 以及下行链路信号发送单元15,被配置为向所述用户设备UE发送所述第一载波中的下行链路信号和所述第二载波中的下行链路信号,其中,所述下行链路信号发送单元15被配置为决定是否发送所述下行链路信号 第一载波基于上行链路信号接收单元17是否在第二载波中接收到上行链路信号。
