论文摘要
多数端技术(例如大量多输入多输出(大型MIMO)和波束形成)是通过智能使用大量天线来增强性能的关键特征。随着即将到来的5G新广播(NR),FD-MIMO(完整的MIMO)将扮演重要角色。 FD-MIMO包括在2D阵列中排列大量天线,该天线能够使用3D波束形成,即在水平和垂直尺寸中均具有光束形成。本文提供了一个3D光束形成的模型,其中光束转向取决于用户的随机空间分布。我们尝试得出有关天线边界辐射模式的概率分布的一些分析结果。同样,通过系统级模拟,我们展示了与传统的2D波束形成相比,3D波束形成如何减少干扰影响,并根据覆盖率概率和用户吞吐量提高系统性能。
Multi-antenna technologies such as massive Multiple-Input Multiple-Output (massive MIMO) and beamforming are key features to enhance performance, in terms of capacity and coverage, by using a large number of antennas intelligently. With the upcoming 5G New Radio (NR), FD-MIMO (Full Dimension MIMO) will play a major key role. FD-MIMO consists in arranging a large number of antennas in a 2D array, which enables to use 3D beamforming i.e., beamforming in both horizontal and vertical dimensions. The present paper provides a 3D beamforming model where beam steering depends on the random spatial distribution of users. We attempt to derive some analytical results regarding the probability distribution of antenna beamforming radiation pattern. Also, through system level simulations, we show how 3D beamforming can reduce interference impact, compared to the traditional 2D beamforming, and enhances system performance in terms of the coverage probability and users throughput.
