摘要:
Disclosed are a radio communication base station device, a radio communication terminal device, and a radio communication method which can reduce interference between adjacent resource blocks even when the DL timing is overlapped with the UL timing at the boundary between an independent allocation band and a cooperation allocation band. When a terminal A is allocated for a UL resource block of the cooperation allocation band serving as a band boundary with the independent allocation band, in ST301, a terminal A transmits a horizontally polarized wave signal to respective terminals B to D, and in ST302, a base station (100) transmits a vertically polarized signal to respective terminals A to D. In ST303, the terminals B to D measure XPD of the received vertically polarized signal and the horizontally polarized signal. In ST304, the terminals B to D transmit the XPD report value to the base station (100). ST305 selects the terminal which has transmitted the largest XPD report value among the XPD report values transmitted from the terminals B to D and allocates the selected terminal to the DL resource block at the band boundary.
