宽带毫米波通信共存问题综述

A Review on Coexistence Issues of Broadband Millimeter-Wave Communications

Ching-Lun Tai, Derek Wu

摘要:

毫米波(mmWave)频带具有比传统频段更高的频率和更宽的频谱,适用于以短距离高速率通信为特征的下一代无线网络。作为一个新来者,毫米波有望与现有服务具有向后兼容性,并与其他技术合作,以提高系统性能。因此,共存问题成为下一代无线通信的重要课题。在本文中,我们系统地回顾了宽带毫米波通信的共存问题及其在文献中提出的相应解决方案,有助于阐明毫米波设计的见解。特别地,本文中所调查的工作可以分为四类:与微波通信的共存、与固定业务的共存、与非正交多址接入(NOMA)的共存以及其他共存问题。数值计算结果的启发,文献中提出了更深入的分析。我们还指出了每个类别的一些挑战和未来方向,作为进一步研究宽带毫米波通信共存问题的路线图。

英文摘要:

With higher frequencies and broader spectrum than conventional frequency bands, the millimeter-wave (mmWave) band is suitable for next-generation wireless networks featuring short-distance high-rate communications. As a newcomer, mmWaves are expected to have the backward compatibility with existing services and collaborate with other technologies in order to enhance system performances. Therefore, the coexistence issues become an essential topic for next-generation wireless communications. In this paper, we systematically review the coexistence issues of broadband mmWave communications and their corresponding solutions proposed in the literature, helping shed light on the insights of the mmWave design. Particularly, the works surveyed in this paper can be classified into four categories: coexistence with microwave communications, coexistence with fixed services, coexistence with non-orthogonal multiple access (NOMA), and other coexistence issues. Results of numerical evaluations inspired by the literature are presented for a deeper analysis. We also point out some challenges and future directions for each category as a roadmap to further investigate the coexistence issues of broadband mmWave communications.
