新型室分系统定位方法的研究

摘要

To solve the problem of inaccuracy of the positioning technology based on proximity relations in the new indoor distribution system scenario, the paper analyzed the new system, and proposed a new positioning method: BBU would analyze the received SRS signal strength of each RRU, then recognized the RRU location with the maximum power of the SRS as the terminal. The method of RRU labeling, distinguishing overlying SRS signals, is easy to realize, and improves positioning accuracy.%为了解决基于临近关系的定位技术在新型室内分布系统场景下存在定位不精确的问题，通过对新型室分系统进行分析，给出了一种基于临近关系的新型室分系统定位方法：BBU分析各个RRU接收到的SRS信号的强度，然后将接收到SRS信号功率最大的RRU的位置作为该终端的位置。其中采用RRU标识的方法，使得叠加在一起的SRS信号被区分开。该定位方法实现简单，并且提高了定位精度。
