Abstract:
A base station apparatus includes a downlink reference signal generation unit configured to generate a first demodulation reference signal and a second demodulation reference signal that are reference signals used to demodulate a data signal, and a radio transmitting unit configured to transmit the first demodulation reference signal, the second demodulation reference signal, and control information to the terminal apparatus. The control information includes parameters regarding the first demodulation reference signal and parameters regarding the second demodulation reference signal. The parameters regarding the first demodulation reference signal include an antenna port number. The parameters regarding the second demodulation reference signal include an antenna port number, and a time domain density or a frequency domain density with which demodulation reference signals are mapped into a slot. The first demodulation reference signal is mapped before the second demodulation reference signal in the slot.
