摘要： In a receiving side apparatus 150, reception quality of receive data is measured by a reception quality measurement section 157, receive data errors are detected by an error detection section 156, and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section 158. In a transmitting side apparatus 100, when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus 150 is detected from a reception quality signal by a scheduling section 110, and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.

摘要： Signals subjected to orthogonal modulation with a plurality of carrier frequencies are added to detect peak power. Based on the peak power, a coefficient for suppressing an amplitude of a transmission baseband signal is calculated. Using the coefficient, the amplitude of a baseband signal to be inputted to a filter is suppressed. It is thereby possible to suppress the peak power assuredly, and by the effects of the filter, unnecessary frequencies are not generated.

摘要： An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.
