摘要
LTE-U是一种在非授权频谱上部署LTE技术以提供电信级移动通信服务的无线接入技术。本文首先研究了LTE-U关键技术,然后从频率使用、载波聚合方案、网络部署策略、干扰规避等方面分析了LTE-U引入对网络规划的影响,针对性的提出了以提升中国移动LTE网络质量与建设效率为目标的LTE-U网络规划策略,为中国移动未来LTE-U部署提供参考。
LTE-U is a radio access technology that has been proposed for providing carrier-grade wireless service in the unlicensed band. This article fi rstly researched the key technologies of LTE-U, secondly analyzed the influence of LTE-U on network planning from spectrum utilization, carrier aggregation schemes,network deployment, and interference avoidance. And then this article put for ward instructive strategies of LTE-U network planning aiming to improve the network quality and construction effi ciency of LTE for CMCC.
