    • Disclosed is a base station capable of minimizing in Type 0 assignment the number of resource block groups occupied by a terminal that performs frequency hopping, and thereby flexibly assigning resources in the Type 0 assignment. The base station (100) is used in a radio communication system in which a plurality of resource blocks constituting the system band thereof are grouped into resource block groups each consisting of P resource blocks, and the band that is not a PUCCH-assignable band to which PUCCHs assigned to both ends of the system band can be assigned is divided into a plurality of sub-bands. The base station (100) comprises an assignment unit (1102) and a demapping unit (112). The assignment unit (1102) assigns a plurality of resource blocks in units of resource block groups to terminal apparatuses to be subjected to noncontiguous-band assignment. The demapping unit (112) extracts, from a plurality of resource blocks in a second band, data signals for which frequencies are hopped by a frequency-hopping terminal apparatus from one to another of the plurality of sub-bands. Here, the bandwidth of each of the plurality of sub-bands is a natural-number multiple of P.
    • 公开了能够在类型0分配中使由执行跳频的终端占用的资源块组的数量最小化的基站,从而灵活地分配类型0分配中的资源。 基站(100)用于将构成其系统频带的多个资源块分组为资源块组的无线通信系统,每个资源块组由P个资源块和不是可分配PUCCH的频带组成, 可以分配分配给系统频带两端的PUCCH被划分为多个子带。 基站(100)包括分配单元(1102)和解映射单元(112)。 分配单元(1102)将以资源块组为单位的多个资源块分配给要进行非连续带分配的终端装置。 解映射单元(112)从第二频带中的多个资源块中提取频率由跳频终端装置从多个子频带中的一个到另一个跳频的数据信号。 这里,多个子带中的每一个的带宽是P的自然数倍数。
