毫米波（mmWave）频段是下一代蜂窝和无线网络的有前途的候选频段。为了补偿由于频率较高而导致的明显更高的路径损耗，毫米波频段通常采用波束形成技术。然而，这给网络拓扑控制带来了很大的挑战。在本文中，我们提出一种新的毫米波网络拓扑控制框架，称为面向波束形成的拓扑控制（BOON）。目标是减少基站的总发射功率和波束之间的干扰。BOON巧妙地将附近的用户设备分组，从用户设备集群中构建集，并将用户设备与基站和波束相关联。我们从发射功率、网络求和速率、信噪比和计算复杂度等方面比较了BOON与现有的三种拓扑控制方案。结果表明，整体的BOON显著优于它们。特别是，BOON平均只使用其他三种方案的10%、32%和25%的发射功率，就能达到相同的网络和速率。
The millimeter wave (mmWave) frequency band is a promising candidate for next generation cellular and wireless networks. To compensate the significantly higher path loss due to the higher frequency, the mmWave band usually uses the beamforming technology. However, this makes the network topology control a great challenge. In this paper, we propose a novel framework for network topology control in mmWave networks, termed Beamforming Oriented tOpology coNtrol (BOON). The objective is to reduce total transmit power of base stations and interference between beams. BOON smartly groups nearby user equipment into clusters, constructs sets from user equipment clusters, and associates user equipment to base stations and beams. We compare BOON with three existing topology control schemes in terms of transmit power, network sum rate, signal to interference and noise ratio, and computation complexity. The results indicate that overall BOON significantly outperforms them. In particular, on average BOON uses only 10, 32, and 25 percent transmit power of other three schemes, respectively, to achieve the same network sum rate.
