摘要： A terminal device includes communication means for carrying out communication with a base station device, and generation means for generating a rank indicator specifying a preferred rank, first partial precoder information and second partial precoder information specifying a preferred precoder, and a reception quality indicator specifying a preferred transmission rate. In a first feedback mode in which reception quality information is reported periodically to the base station device, the communication means reports the second partial precoder information and the reception quality indicator at first timing, and reports the rank indicator and the first partial precoder information at second timing different from the first timing. In a second feedback mode in which the reception quality information is reported aperiodically to the base station device, the communication means reports the rank indicator, the first partial precoder information, the second partial precoder information, and the reception quality indicator at the same timing.

摘要： A base station is provided in which a terminal efficiently controls a demodulation reference signal for a data signal transmitted from the base station in a wireless communication system in which the base station and the terminal communicates with each other. The base station that performs a communication with the terminal includes a data signal generation unit that generates a data signal for terminal, and a demodulation reference signal for a data signal multiplexing unit that multiplexes a demodulation reference signal for a data signal, which is a known signal for demodulating the data signal, into the data signal. The scramble code included in the demodulation reference signal for the data signal is generated based on a first scramble ID and a second scramble ID that are notified from the base station to the terminal.
