摘要:

第六代(6G)无线系统在全面实施后,将构成智能无线网络,不仅能够实现无处不在的通信,还能提供高精度的定位服务。它们将通过引入一套新的特征和服务能力成为这一转变的驱动力,在这种特征和服务能力中,位置将与通信共存,同时共享可用资源。为此,本调查调查了未来6G无线系统中本地化的预期应用和用例,同时分析了主要技术推动因素的影响。之后,系统模型的毫米波,太赫兹和可见光定位,同时考虑到视线(LOS)和非LOS信道,而本地化的关键性能指标一起重新审视数学定义。此外,最先进的传统和基于学习的定位技术的状态进行了详细的审查。此外,制定的定位问题,无线系统的设计被认为是和两者的优化研究。最后,从所提出的分析中产生的见解进行了总结,并用于突出在6G无线系统本地化的最重要的未来方向。

英文摘要:

When fully implemented, sixth generation (6G) wireless systems will constitute intelligent wireless networks that enable not only ubiquitous communication but also high-accuracy localization services. They will be the driving force behind this transformation by introducing a new set of characteristics and service capabilities in which location will coexist with communication while sharing available resources. To that purpose, this survey investigates the envisioned applications and use cases of localization in future 6G wireless systems, while analyzing the impact of the major technology enablers. Afterwards, system models for millimeter wave, terahertz and visible light positioning that take into account both line-of-sight (LOS) and non-LOS channels are presented, while localization key performance indicators are revisited alongside mathematical definitions. Moreover, a detailed review of the state of the art conventional and learning-based localization techniques is conducted. Furthermore, the localization problem is formulated, the wireless system design is considered and the optimization of both is investigated. Finally, insights that arise from the presented analysis are summarized and used to highlight the most important future directions for localization in 6G wireless systems.
