LTE-Advanced CoMP技术现网应用研究

摘要

Principles and key points of LTE-Advanced CoMP technique were addressed in this paper. Reforming the hardware, software and transmission system in existing network and adding artificial interference to simulate the interference of adjacent cells to the current cell, both the performance of CoMP technique and the feasibility of network parameter configuration in current network scenario of LTE BBU centralized deployment were tested. Results verify that CoMP technique is beneficial for rate enhancement of network-edge users.%对LTE-Advanced的CoMP技术原理及关键过程进行了阐述，通过提出在现网中进行硬件、软件及传输系统的改造，并且进行人为加载以模拟邻区对本小区的干扰等方法，测试了在LTE BBU集中部署的现网场景下，CoMP技术应用的性能及网络参数设置的合理性，验证了CoMP技术对现网边缘用户速率的提升有一定的帮助。
