论文摘要
下一代无线网络正面临频谱短缺挑战，这主要是由于预计的大量物联网连接以及此类网络应该服务的新兴带宽应用程序。频谱稀缺且昂贵，因此，设计动态和灵活的频谱访问策略和技术至关重要，从而产生这种宝贵资源的最佳用途。最近，一种新趋势被用作解决这种频谱稀缺挑战的关键解决方案是利用较高的频段，即MMMWAVE频段，这些趋势是几年前被认为是不切实际的，但由于最近的电子产品的进步，现在正变得可行。但是，幸运的是，光谱监管机构通过允许在MMWave频率中使用新频段来做出响应，但仍需要做很多工作才能从此类新光谱中受益。 在本文中，我们讨论了一些与MMWave频率下动态频谱访问有关的一些关键频谱管理挑战，这些挑战需要克服，以促进在这些MMWave频段上促进动态频谱共享。我们还提出了新技术，通过应对一些讨论的挑战，可以在MMWave频段上进行有效的动态频谱共享，并强调仍需要解决的开放研究挑战，以完全释放MMWAVE频段的动态频谱共享潜力。
Next-generation wireless networks are facing spectrum shortage challenges, mainly due to, among other factors, the projected massive numbers of IoT connections and the emerging bandwidth-hungry applications that such networks ought to serve. Spectrum is scarce and expensive, and therefore, it is of crucial importance to devise dynamic and flexible spectrum access policies and techniques that yield optimal usage of such a precious resource. A new trend recently being adopted as a key solution to this spectrum scarcity challenge is to exploit higher frequency bands, namely mmWave bands, that were considered impractical few years ago, but are now becoming feasible due to recent advances in electronics. Though, fortunately, spectrum regulatory bodies have responded by allowing the use of new bands in the mmWave frequencies, much work still needs to be done to benefit from such new spectra. In this paper, we discuss some key spectrum management challenges that pertain to dynamic spectrum access at the mmWave frequencies, which need to be overcome in order to promote dynamic spectrum sharing at these mmWave bands. We also propose new techniques that enable efficient dynamic spectrum sharing at the mmWave bands by addressing some of the discussed challenges, and highlight open research challenges that still need to be addressed to fully unleash the potential of dynamic spectrum sharing at mmWave bands.
