摘要： A transmitting device includes a transmission signal generating unit configured to generate a transmission signal by inverse-Fourier-transforming reference signals and data signals mapped to subcarriers and a transmitting unit configured to wirelessly transmit the transmission signal. In the transmitting device, a total power level allocated to signals to be transmitted in a time slot is equal to a total power level allocated to signals to be transmitted in any other time slot, and a power density per unit bandwidth of the reference signals is greater than a power density per unit bandwidth of the data signals. This configuration makes it possible to equalize the total transmission power level of all time slots and thereby to improve the power amplification efficiency. Also, with this configuration, since the reference signals are transmitted with a higher power than that for other signals, it is possible to improve the accuracy of channel estimation.

摘要： Multiple reference signal transmission bandwidths are defined for system frequency bands and hierarchical reference signal bandwidths are defined for each reference signal transmission bandwidth such that a reference signal bandwidth lower than a highest-order reference signal bandwidth is a division of a higher-order reference signal bandwidth. A base station stores reference signal bandwidth information indicating the hierarchical reference signal bandwidths for each system frequency band; broadcasts the reference signal bandwidth information corresponding to a reference signal transmission bandwidth used by the base station; sets a frequency hopping bandwidth for a reference signal; reports, to a user device, the frequency hopping bandwidth and a reference signal bandwidth as assigned reference signal transmission bandwidth information; sets a reference signal transmission frequency band within the frequency hopping bandwidth based on the reference signal bandwidth information and the assigned reference signal transmission bandwidth information; and receives the reference signal from the user device.

摘要： A disclosed radio base station is used in a mobile communication system employing a single carrier scheme for uplink and includes a scheduler configured to allocate radio resources such that a first control channel accompanying an uplink data channel is transmitted using the same frequency band allocated to the uplink data channel and a second control channel, which is to be transmitted regardless of presence or absence of the uplink data channel, is transmitted using a dedicated frequency band reserved for the second control channel if no frequency band is allocated to the uplink data channel; and a reporting unit configured to report scheduling information indicating the allocation results to a user device. The scheduler is configured not to allocate the radio resources to the uplink data channel of the user device in a unit transmission period reserved for transmission of the second control channel of the user device.
