摘要： Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit (117) determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit (117) increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).

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.

摘要： Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

A reception quality and an offset corresponding to the calculated PER are fed back to a transmitting apparatus. The transmitting apparatus assigns, based on the fed-back reception quality and offset, the streams, thereby controlling the stream multiplex number.

摘要： It is possible to prevent lowering of a throughput of a radio communication system even when propagation path environments of an uplink line and downlink line are asymmetric. A maximum proper value calculation unit (115) calculates a maximum proper value from a channel matrix. A maximum proper value comparison unit (116) compares the maximum proper value with a maximum proper value of the downlink line reported separately from a base station. According to the comparison result obtained by the maximum proper value comparison unit (116), a proper mode initiative instruction unit (117) decides to pass the proper mode initiative to a communication partner or to the local device. When the initiative is to be passed to the local device, this fact is reported to a proper bam correction unit (118). When the proper beam correction unit (118) gets the proper mode initiative, the proper beam correction unit (118) corrects the correlation matrix by using the proper values of both of the downlink line and the uplink line and instructs a directivity forming unit (103) to form a proper beam according to the correlation matrix after the correction.
