Abstract
Improvement of transmission efficiency is sought by stopping transmission of unnecessary MLI data. A transmitting circuitin a base station apparatushas an MLI modulation partcomposed of an MLI generating circuit, a symbol modulation circuit, and an IFFT circuit, a user data modulation partcomposed of an encoder circuit, a symbol modulation circuit, a transmission power control circuit, and an IFFT circuit, and a transmission operation control circuit. The transmission operation control circuitcontrols operation timing of the MLI modulation part, the user datamodulationpart, and a multiplexerbased on a signal to notify that ACK input from a receiving circuithas been received so that slots containing no MLI data are generated.
