摘要： It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (100) used in a radio communication system using different frequency bands for the upstream line and the downstream line, an upstream line pilot generation unit (115) forms a CQI measuring pilot signal and an upstream line RF unit (105) transmits the communication quality measuring pilot signal by using the upstream line use frequency band in the upstream line pilot transmission section. Thus, the upstream communication quality measuring pilot signal used by the radio base station device (100) to measure the line quality is transmitted by using the upstream line frequency band and accordingly, it is possible to reduce the power consumption in the radio terminal device.

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： A radio transmitting apparatus wherein even if a preamble sequence transmitted via any one of the antennas of the radio transmitting apparatus is detected, the order of the space diversity can be determined with reliability and data signals can be normally decoded. In this apparatus, a deciding unit (101) decides preamble sequences the number of which is equal to the order of the space diversity and further decides transmission block intervals the number of which is equal to or greater than the order of the space diversity. An allocating unit (102) sequentially allocates the preamble sequences, the number of which is equal to the order of the space diversity, to the respective antennas, the number of which is equal to the order of the space diversity, within the respective transmission block intervals. The allocating unit (102) allocates different ones of the preamble sequences to the respective antennas at the respective same transmission timings that are within the respective transmission block intervals.
