Abstract:
1. A radio communication terminal apparatus comprising: a receiver configured to receive notification information for notifying an amount of cyclic shift used for a reference signal; a determination unit configured to determine the amount of cyclic shift corresponding to the received notification information for a data demodulation reference signal or a sounding reference signal, an amount of cyclic shift not included in the amount of cyclic shift for the data demodulation reference signal being set as the amount of cyclic shift for the sounding reference signal and being associated with the notification information along with the amount of cyclic shift for the data demodulation reference signal; and a transmitter configured to transmit the data demodulation reference signal or the sounding reference signal using the determined amount of cyclic shift, wherein the determination unit applies, when no inter-slot frequency hopping is performed, the amount of cyclic shift for the sounding reference signal associated with the amount of cyclic shift obtained by shifting the amount of cyclic shift for the data demodulation reference signal by one, and applies, when inter-slot frequency hopping is performed, the amount of cyclic shift for the data demodulation reference signal as the amount of cyclic shift for the sounding reference signal.
