    • In ARQ where a plurality of mobile stations share and use a single channel for response signals (ACK/NACK signals), a wireless communication base station apparatus can prevent failure of the ARQ control. In this apparatus, a CRC part (114) performs an error detection using CRC for an uplink data, and generates, as a response signal, an ACK signal in a case of CRC=OK or a NACK signal in a case of CRC=NG. A retransmittal determining part (115) determines whether the response signal is for an initially transmitted data or for a retransmitted data. A constellation control part (116) controls, in accordance with a determination result of the retransmittal determining part (115), a constellation pattern to be used in a modulation in a modulating part (105). The modulating part (105) modulates the response signal for the retransmitted data in accordance with the constellation pattern controlled by the constellation control part (116), that is, a constellation pattern obtained by reversing the constellation pattern of the response signal for the initially transmitted data.
    • 在多个移动站共享并使用单个信道作为响应信号(ACK / NACK信号)的ARQ中,无线通信基站装置能够防止ARQ控制失败。 在该装置中,CRC部分(114)对于上行链路数据执行CRC校验的错误检测,在CRC = OK的情况下生成ACK信号作为响应信号,在CRC = NG的情况下,生成NACK信号 。 重传确定部分(115)确定响应信号是针对最初发送的数据还是用于重传的数据。 星座控制部分(116)根据重传确定部分(115)的确定结果,控制要在调制部分(105)中的调制中使用的星座图案。 调制部分(105)根据由星座控制部分(116)控制的星座图案调制重发数据的响应信号,即通过反转最初发送的响应信号的星座图案而获得的星座图案 数据。

    • Provided is a multicarrier communication apparatus by which information quantity of CQI reporting can be reduced. In the apparatus, each CQI is recorded in a CQI table section (122) by being classified into a plurality of CQI groups by following a certain rule. A CQI selecting section (123) estimates fluctuation range and variance of reception qualities of the entire resource block to be reported, based on an SINR value outputted from a quality level calculating section (121). Then, based on the estimated values, the CQI selecting section selects a suitable CQI group in a first step, selects a suitable CQI value from among the CQIs included in the selected CQI group in a second step, and outputs the ID of the selected CQI group and the selected CQI value to a CQI generating section (124) . Based on such information, the CQI generating section (124) generates a CQI frame to be transmitted to a base station.
