摘要

传统二维有源天线仅能进行水平维波束调整，而三维有源天线能进行垂直维波束调整，提升系统吞吐量。现有的三维有源天线波束下倾角选择方法是基于俯仰角信息进行选择的，用户信号接收功率较低。为此，提出一种新颖的三维有源天线基站组网波束下倾角选择方法，该方法基于参考信号接收功率信息进行波束下倾角选择，有效提高了用户信号接收功率。仿真结果表明，新方法可大幅提升小区平均吞吐量，改善系统性能。

Abstract

Traditional 2D active antenna system can only carry on horizontal beam steering in cellular mobile radio system. The existing 3D active antenna system based cellular network can obtain large throughput gain with the use of vertical beam steering. The existing beam downtilt selection method for 3D active antenna system is based on the information of pitch angle. The received power of the user is very low. A novel beam downtilt selection method for 3D active antenna system was proposed to improve the received power

which is based on the received reference signal power. Simulation results show that the proposed method can improve the average throughput of the cell and the system performance sharply.
