本文介绍了 LTE-Advanced 第三代合作伙伴项目中多个小区站点之间的一种精细协调技术，称为协调多点传输和接收。在解决了 LTE 第 8 版规范中的主要无线接入技术之后，描述了满足 LTE-Advanced 要求的系统要求和应用的无线接入技术，包括 CoMP 传输和接收。然后介绍了3GPP中已商定或目前正在讨论的CoMP传输和接收方案以及相关的无线接口。最后，系统级仿真评估表明，基于LTE-Advanced仿真条件，CoMP发送和接收方案在提高小区边缘用户吞吐量方面具有显着效果。
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.
