Abstract:
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.
