Abstract

In next generation of mobile networks, the 5G, millimeter-wave communication is considered one of the key technologies. It allows high data rate as well as the utilization of large antennas for massive multiple-input-multiple-output (MIMO) and beamforming. However, it is mandatory that transmitter and receiver perform a training of their beams in order to gain all the benefits of a large array gain. In this paper, we study the impact of the beamtraining overhead on the data rate when an exhaustive or hierarchical strategy is used. Also, we show that the beamtraining phase can be used for positioning and, in this regard, we study the trade-off between positioning and data rate.
速率-定位权衡视角下不同波束训练策略的比较
在下一代移动网络5G中,毫米波通信被认为是关键技术之一。它允许高数据速率以及大规模多输入多输出(MIMO)和波束形成的大型天线的利用。然而,为了获得大阵列增益的所有好处,发射器和接收器必须对它们的波束进行训练。在本文中,我们研究了当使用穷尽或分层策略时,波束训练开销对数据速率的影响。此外,我们表明波束训练阶段可以用于定位,在这方面,我们研究了定位和数据速率之间的权衡。
