1. A terminal for transmitting a reference signal in a radio communication system, the terminal comprising:
a demodulation reference signal transmitter configured to transmit a demodulation reference signal at a particular time point in a subframe of a radio resource for uplink reference signal transmission, the particular time point being determined based on a data channel; and
a tracking reference signal transmitter configured to transmit a tracking reference signal for a particular duration in the subframe of the radio resource, the particular duration being determined based on the data channel,
wherein
the data channel is assigned to a symbol period in a plurality of symbols included in the subframe, the symbol period having consecutive symbols among the plurality of symbols,
the particular time point corresponds to the first symbol of the symbol period where the transmission of the data channel is started,
the transmission of the data channel and the transmission of the demodulation reference signal are started at the first symbol of the symbol period in the frame,
the particular duration corresponds to the symbol period in the subframe, and
the data channel and the tracking reference signal are transmitted during the symbol period in the frame.
