Abstract

Wireless optical transmission has been included in 6G framework as a promising solution to break through the bottleneck of radio transmission in limited bandwidth as well as to facilitate the integrated space-air-ground network. Since the laser beam is vulnerable to atmospheric conditions, cooperative communication is introduced as a viable way to enhance the received signal strength of wireless optical links. In 6G era, wireless optical communication is anticipated for the high-speed interconnection among the aerial and spatial terminals with which cooperative communication can be readily implemented. Related works on wireless optical cooperative communication mostly inherit the enabling techniques from the wireless radio counterpart, while cooperative communication has not yet been invented toward the characteristics of wireless optical links. In this article, we aim to reveal the potential challenges and opportunities for wireless optical communication in 6G and propose a distinguished technological framework for wireless optical cooperative communication. The proposed framework can not only extend the prospect of cooperative communication but also help direct the way that wireless optical communication evolves in 6G.

无线光学系统中如何区分协同通信

无线光传输已被纳入6G框架，作为突破有限带宽下无线电传输瓶颈、促进天空地一体化网络的一种有希望的解决方案。由于激光束容易受到大气条件的影响，因此引入合作通信作为增强无线光链路接收信号强度的可行方法。在6G时代，无线光通信有望实现空中和空间终端之间的高速互联，实现协同通信。无线光协同通信的相关工作大多继承了无线无线电对应物的使能技术，而针对无线光链路的特点，协作通信尚未发明。在本文中，我们旨在揭示6G无线光通信的潜在挑战和机遇，并提出一种独特的无线光协同通信技术框架。提出的框架不仅可以拓展协同通信的前景，而且有助于指导6G无线光通信的发展方向。
