摘要： A base station communicates with a user device transmitting an uplink signal based on a single-carrier transmission scheme. The base station includes a frequency hopping determining unit configured to determine whether to apply frequency hopping to the user device based on radio-wave propagation information from the user device and a traffic type of data to be transmitted by the user device; a scheduler configured to allocate frequencies to the user device based on uplink channel reception conditions of the user device; and a reporting unit configured to report allocation information indicating resource units allocated by the scheduler to the user device. When the frequency hopping determining unit determines to apply the frequency hopping to the user device, the scheduler allocates, to the user device, resource units with different frequency bands in different slots.

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.
