摘要

本文基于用户体验

以平均单用户速率不低于2 Mbit/s为基础指标

通过对影响4G网络容量的因素进行分析

提出了一种4G网络扩容策略

对应PRB利用率不同的增长情况下

根据扇区的载频类型确定扩容频段步骤及规模。当频段资源用满时

则可通过对站点进行3D-MIMO改造来提升系统容量。最终可输出扩容小区清单

以满足未来2～3年内4G网络快速增长的容量需求。

Abstract

This paper presents a TD-LTE capacity expansion strategy based on the analysis of factors affecting the capacity of 4G network and user experience which the average single user rate is above 2 Mbit/s. Under different growth rates of PRB utilization

the steps and scales of the expansion based on the carrier type of sector are given. And 3D-MIMO can be an effective method to improve system capacity when the frequency bands are used up. As a result

the expansion list can be provided to guide the construction of 4G network in future years.
