-Coordinatedmulti-pointtransmission/reception
(CoMP) technique for 3GPP LTE-Advanced isto reduce the
inter-cellinterference(ICI)effectively, so as to enhance data
rate/coverage and throughput for cell-edge users significantly.
For downlink CoMP, most research work mainly focuses on
joint processing/transmission (CoMP-JP) mode. However this
mode needs the access points (AP) to share the UEs' data and
channel state information (CSI) simultaneously, resulting ina
high overhead onthenetwork. Coordinated beam forming
(CoMP-CBF), which can avoid the data information exchange
is a better solution to reduce the overhead. In this paper, we
propose acoordinatedbeam formingschemeindownlink
CoMP transmission system. The proposed scheme exploits the

precoding vector toreduce theICI.The simulation results
indicatethattheproposedschemeoffersmuch higher
performance gain compared with the CoMP-JP mode.
