COORDINATED MULTIPOINT TRANSMISSION/RECEPTION TECHNIQUES FOR LTE-ADVANCED

BSTRACT

This article presents an elaborate coordination
technique among multiple cell sites called
coordinated multipoint transmission and reception
in the Third Generation Partnership Project
for LTE-Advanced. After addressing major radio
access techniques in the LTE Release 8 specifications,
system requirements and applied radio
access techniques that satisfy the requirements
for LTE-Advanced are described including
CoMP transmission and reception. Then CoMP
transmission and reception schemes and the
related radio interface, which were agreed upon
or are currently being discussed in the 3GPP, are
presented. Finally, system-level simulation evaluations
show that the CoMP transmission and
reception schemes have a significant effect in
terms of improving the cell edge user throughput

based on LTE-Advanced simulation conditions.
