    • A wireless communication device according to the invention includes a reception section that receives a downlink signal in a first subframe from another wireless communication device; an ACK/NACK generation section that generates ACK/NACK which indicates an error determination result of the received downlink signal; a determination section that determines, when an uplink signal directed to the other wireless communication device is not allocated in a second subframe, whether a different uplink signal is allocated in a third subframe subsequent to the first subframe by a predetermined number of subframes and previous to the second subframe; a multiplexing section that multiplexes the ACK/NACK to the different uplink signal in the third subframe when the determination section determines that the different uplink signal is allocated in the third subframe; and a transmission section that transmits the different uplink signal in which the ACK/NACK is multiplexed by the multiplexing section.

    • Provided are a radio terminal, a radio base station, a channel signal forming method, and a channel signal receiving method, by which the number of blinds in the processing for receiving allocation control information is reduced without causing disadvantage regarding the reception of a broadcast channel signal. In a base station (100), an information size adjustment unit (103) uses, in a common search space in a downlink additional unit band, the larger of the information size of downlink allocation control information determined from the bandwidth of a downlink additional unit band and the information size of uplink allocation control information determined from the bandwidth of an uplink unit band associated with the downlink additional unit band by a broadcast channel signal transmitted in the downlink additional unit band, as a size adjustment reference, and uses, in a UE specific search space, the larger of the information size of the downlink allocation control information determined from the bandwidth of the downlink additional unit band and the information size of the uplink allocation control information determined from the bandwidth of the uplink unit band of a unit band group, as the size adjustment reference.
    • 提供一种无线电终端,无线电基站,信道信号形成方法和信道信号接收方法,通过该方法减少用于接收分配控制信息的处理中的盲目数,而不会导致广播信道的接收的缺点 信号。 在基站(100)中,信息量调整单元(103)在下行链路附加单位频带的公共搜索空间中,使用从下行链路附加单元的带宽确定的下行链路分配控制信息的信息大小越大 并且通过在下行链路附加单位频带中发送的广播信道信号从与下行链路附加单位频带相关联的上行链路单位频带的带宽确定的上行链路分配控制信息的信息大小作为尺寸调整参考,并且在 UE特定搜索空间,从下行链路附加单位频带的带宽确定的下行链路分配控制信息的信息大小越大,从单位频带的上行链路单位频带的带宽确定的上行链路分配控制信息的信息大小越大 组,作为尺寸调整参考。
