Disclosed are a radio transmission device and a radio transmission method capable of reducing a reception error of a user at other cell and improving transmission efficiency at the other cell when frequency scheduling is combined with beam forming. In the device and the method, a beam allocation table storage unit (101) has a table in which resource blocks bm1, bm2, bm3, bm4 arranged in the ascending order of the frequency are repeatedly allocated by using four beams bm1 to bm4 for the number of resource blocks fn. According to beam information and SIR information fed back from a reception device (150), a resource control unit (102) references the beam allocation table storage unit (101), selects a combination of a beam direction and a resource block having the most preferable SIR, and allocates the combination for the user.
