Abstract:
Provided is a radio communication device which can separate propagation paths of antenna ports and improve a channel estimation accuracy even when using virtual antennas. The device includes: a mapping unit which maps a data signal after modulation to a virtual antenna and a virtual antenna; a phase inversion unit which inverts the phase of S0 transmitted from an antenna port in synchronization with a phase inversion unit between the odd-number slot and the even-number slot; the phase inversion unit which inverts the phase of R0 transmitted from the antenna port; a phase inversion unit which inverts the phase of S1 transmitted from an antenna port in synchronization with a phase inversion unit; and the phase inversion unit which inverts the phase of R1 transmitted from an antenna port.

Claim (Index 19):
The communication method according to  claim 18  wherein the number of antenna ports configured for the mobile station is 4 or less when the first reference signals are used for channel quality estimation, and the number of antenna ports configured for the mobile station is 8 when the second reference signals are used for channel quality estimation.
