Abstract
A reference signal specific to each base station device and a reference signal specific to each mobile station device are not mixed within one OFDM symbol of a resource block and OFDM symbols including the reference signal specific to each mobile station device are arranged at regular intervals on a time axis. By using such a signal arrangement pattern it is possible to overcome the problems in Non-Patent Document 1 mentioned above caused by mixing a reference signal specific to each base station device and a reference signal specific to each mobile station device in one OFDM symbol. Thus it becomes possible to prevent the reference signal specific to each base station device and the reference signal specific to each mobile station device from being mixed within one OFDM symbol of a resource block.

transmitting said data, said reference signal specific to the base station, and said reference signal specific to the mobile station allocated in said third domain.
2. The method according to claim 1, wherein ratios of the transmit power of the first domain having the data and of the transmit power of the first domain having the reference signal specific to the mobile station are made equal across a plurality of the second domains having the reference signal specific to the mobile station.
3. The method according to claim 2, wherein the transmit power of the first domain having the data and the transmit power of the first domain having the reference signal specific to the mobile station are made equal within the second domain having the reference signal specific to the mobile station.
4. The method according to claim 3, wherein said base station performs beamforming with respect to the mobile station.
5. The method according to claim 4, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
6. The method according to claim 3, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
7. The method according to claim 2, wherein said base station performs beamforming with respect to the mobile station.
8. The method according to claim 7, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
9. The method according to claim 2, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
10. The method according to claim 1, wherein the transmit power of the first domain having the data and the transmit power of the first domain having the reference signal specific to the mobile station are made equal within the second domain having the reference signal specific to the mobile station.
11. The method according to claim 10, wherein said base station performs beamforming with respect to the mobile station.
12. The method according to claim 11, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
13. The method according to claim 10, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
14. The method according to claim 1, wherein said base station performs beamforming with respect to the mobile station.
15. The method according to claim 14, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
16. The method according to claim 1, further comprising:
receiving the transmitted data; and
performing demodulation using ratios of the power of the reference signal specific to said base station, of the transmitted data, and of the reference signal specific to the mobile station.
17. A base station comprising:
an allocation unit configured to:
allocate data, a reference signal specific to said base station, or a reference signal specific to a mobile station onto a first domain defined by frequency and time;
allocate a plurality of first domains in a frequency direction, said allocation of said plurality of first domains representing a second domain; and
