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.
