Claim
1. A terminal for transmitting a reference signal in a radio communication system, the apparatus comprising:
a first reference signal transmitter configured to transmit a first 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 second reference signal transmitter configured to transmit a second 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 first 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 second reference signal are transmitted during the symbol period in the frame.
2. The terminal as claimed in claim 1, wherein the first reference signal transmitter and the second reference signal transmitter are configured to allocate at least one of a frequency resource and a time resource for the first reference signal and the second reference signal for uplink transmission which is multiple of at least one of a frequency resource and a time resource allocated for the first reference signal and the second reference signal for downlink transmission.
3. The terminal as claimed in claim 1, wherein the first reference signal transmitter is configured to transmit the first reference signal in a frequency domain of the first symbol.
4. The terminal as claimed in claim 1, wherein the second reference signal transmitter is configured to transmit the second reference signal in one of remaining frequency blocks in which the first reference signal is not transmitted in frequency domain of the symbol period.
5. The terminal as claimed in claim 3, wherein, when the first reference signal is transmitted to a reception apparatus through each of multiple antenna beams, the first reference signal transmitter is configured to:
allocate at least two orthogonal frequency blocks for each of the multiple antenna beams by frequency division multiplexing (FDM) process for the frequency domain of the first symbol; and transmit the first reference signal in the at least two allocated frequency blocks of the frequency domain of the first symbol through each of the multiple antenna beams.
6. The terminal as claimed in claim 5, wherein, when the second reference signal is transmitted to the reception apparatus through each of the multiple antenna beams, the second reference signal transmitter is configured to transmit the second reference signal in each of the orthogonal frequency blocks of frequency domain of the particular symbol period.
7. The terminal as claimed in claim 6, wherein the orthogonal frequency blocks transmitting the second reference signal for the multiple antenna beams is allocated to be corresponding to one of the frequency blocks transmitting the first reference signal for other antenna beam.
8. The terminal as claimed in claim 5, wherein when the first reference signal transmitter transmits the first reference signal through the multiple antenna beams, the first reference signal transmitter is configured to puncture a frequency block corresponding to a frequency block transmitting the second reference signal for other antenna beam.
9. A method for transmitting a reference signal by a terminal in a radio communication system, the method comprising:
transmitting a first 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 transmitting a second reference signal for a particular duration in the subframe of the radio resource, the particular duration being determined based on a 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 first 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 second reference signal are transmitted during the symbol period in the frame.
10. The method as claimed in claim 9, wherein:
transmitting the first reference signal comprises transmitting the first reference signal in a frequency domain of the first symbol; and transmitting the second reference signal comprises transmitting the second reference signal in one of remaining frequency blocks in which the first reference signal is not transmitted in frequency domain of the symbol period.
11. The method as claimed in claim 9, wherein:
transmitting the first reference signal comprises, when the first reference signal is transmitted to a reception apparatus through each of multiple antenna beams; allocating at least two orthogonal frequency blocks for each of the multiple antenna beams by frequency division multiplexing (FDM) process for the frequency domain of the first symbol; and transmitting the first reference signal in the at least two allocated frequency blocks of the frequency domain of the first symbol through each of the multiple antenna beams.
12. The method as claimed in claim 11, wherein transmitting the second reference signal comprises, when the second reference signal is transmitted to the reception apparatus through each of the multiple antenna beams, transmitting the second reference signal in each of the orthogonal frequency blocks of frequency domain of the symbol period.
13. The method as claimed in claim 12, wherein the orthogonal frequency blocks transmitting the second reference signal for the multiple antenna beams is allocated to be corresponding to one of the frequency blocks transmitting the first reference signal for other antenna beam.
14. The method as claimed in claim 11, wherein transmitting the first reference signal comprises, when the first reference signal transmitter transmits the first reference signal through the multiple antenna beams, puncturing a frequency block corresponding to a frequency block transmitting the second reference signal for other antenna beam.
