摘　　要：根据TD-LTE移动通信系统原理和实际外场测试的结果,提出提升该系统边缘用户感知的必要性。进一步根据R10/R11协议定义的基于BBU池的协作多点(CoMP)技术,探讨其在分布式BBU部署场景下应用于下行链路并作用于现有R8/R9终端的必要性及其方法。通过仿真和实际的外场验证表明,分布式BBU部署下,采用传输互联达成协作的技术能够有效提升边缘用户的吞吐量,从而提升用户感知。Based on the principle and the field test results of TD-LTE mobile system, it is very necessary to improve the perception of edge users. According to the coordinated multi-point （CoMP） defined in R10/R11 protocol based on BBU pool, it is still necessary to find a way to apply CoMP to the downlink and the current R8/R9 terminal in scenario with distributed BBU. The method to make cells cooperate with each other through transmission is proposed, simulated, realized and tested. According to the simulation results and test results in scenario with distributed BBU, the proposed method can effectively increase the throughput of edge users so that it can improve the user perception.
