摘要：
Coordinated Multi-Point (CoMP) transmission is a technology targeted for Long Term Evolution Advanced (LTE-A).It is designed to reduce cell-edge interference,improve cell-edge spectrum efficiency and enlarge effective cell-edge coverage by means of multi-point coordination including coordination between Remote Radio Units (RRUs) within an eNodeB,coordination between an eNodeB and its relays,and coordination between eNodeBs.The Joint Processing (JP) technique for CoMP can maximize system performance,which is achieved mainly with channel information-based precoding algorithms.Precoding methods perform differently in various CoMP scenarios.Currently,research focuses on compressing the feedback and optimizing codebook design in order to optimize precoding algorithms.
