摘要： A DMRS generator generates reference signals used for demodulation to which orthogonal codes, which are a code for one layer and a code for another layer being orthogonal to each other, are assigned. Concerning each of layers up to the predetermined number of layers, codes are assigned to the reference signals according to the same rules as assignment rules employed in a different terminal device. Accordingly, the throughput can be increased.

摘要： A wireless communication system includes: wireless transmission devices; and a wireless reception device. Each of the wireless transmission devices is configured to transmit data by transforming a time domain signal into frequency domain signals to obtain first frequency signals, clipping a part of the first frequency signals to generate second frequency signals, and allocating the second frequency signals onto subcarriers. The wireless reception device is configured to demodulate, from signals received, time domain data transmitted. Communication is performed using a clipping rate set for each of the wireless transmission devices, the clipping rate being the number of the second frequency signals divided by the number of the first frequency signals.

摘要： In SORM (Spectrum-Overlapped Resource Allocation), interference to other cells caused by an increase in transmit power of mobile station apparatuses is suppressed. A wireless control apparatus allows a plurality of wireless terminal apparatuses to locate transmit signals at part of frequencies in a system band in an overlapping manner, and determines frequencies at which the individual wireless terminal apparatuses locate transmit signals, so that an interference level of the entire system band is suppressed to be lower than or equal to a certain value. Also, the wireless control apparatus determines frequencies at which the individual wireless terminal apparatuses locate transmit signals, so that a total sum of frequency bands allocated to the individual wireless terminal apparatuses is smaller than or equal to the system band.
