    摘要： A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

    摘要： Disclosed is a base station which can prevent degradation in the reception characteristics of nearby cells when carrier aggregation and channel selection are applied. In accordance with the resistance to interference of a plurality of uplink component carriers of a femtocell, a response protocol controller (101) in a base station (100) changes combination rules for the uplink component carriers and signal points which a terminal (200) in a microcell covered by the base station (100) uses in the feedback of a response signal. Information in relation to the combination rules is notified to the terminal (200). A controller (217) in the terminal (200) changes the combination rules for the uplink component carriers and the signal points of the microcell covered by the base station (100) in accordance with the information notified from the base station (100), and controls transmission of the response signal in accordance with said rules.

    摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.
