Title:
RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/083699
Kind Code:
A1
Abstract:
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.
