一种FDD1800 MHz 4T4R扇区劈裂方法的研究及应用

Research and application of FDD1800 MHz 4T4R sector splitting method

随着4G流量的迅猛增长以及目前TDD频段满扩,FDD1800 MHz扩频至20 MHz仍无法实现用户感知良好。本文研究通过FDD1800 MHz 4T4R扇区劈裂的新方法解决区域容量问题。网络验证结果表明,扇区劈裂技术不仅具有对网络改动小、施工难度低和部署开通快的优点,而且在5G分流效果有限的部署初期阶段,该方案能用较低的成本有效解决热点区域的高负荷问题,达到降本增效的目的。

With the rapid growth of 4G traffic and the current situation which TDD band full expansion,FDD1800 MHz can't meet users'good perception after spreading to 20 MHz,this paper studies a new method to solve the problem of regional capacity by FDD1800 MHz 4T4R sector splitting.The verifi cation result shows that sector splitting technology not only has the advantages of small changes to the existing network,low construction difficulty and fast deployment,but also in the 5G initial deployment phase with limited diversion effect,the scheme can effectively solve the problem of high load in hot spots with a lower cost,so as to achieve the purpose of reducing cost and increasing effi ciency.
