2026-05-20

AI Summary

Current brain–computer interfaces (BCIs) face significant limitations in real-time neural signal transmission due to constrained bandwidth, insufficient security, and limited automation, hindering reliable, low-latency brain–device interaction. This work presents the first systematic framework for 6G-enabled BCIs, integrating key 6G technologies—such as intelligent edge computing, touchless networking, and cognitive communications—to substantially enhance neural data transmission rates, security, and autonomy. The study introduces a novel paradigm that fuses cognitive communications with advanced neural interfaces, thereby enabling emerging applications including digital twins, immersive communication, and the “Internet of Minds.” Furthermore, it outlines critical technical pathways, representative use cases, and open challenges, offering a comprehensive roadmap for future research in this transformative domain.

Abstract

Brain computer interface (BCI) enables the brain to directly control an external device by converting neural signals into actionable outputs. However, effective real-time translation of brain activity strongly depends on the quality of neural communication between the brain and the external device. 6G is the next generation of wireless communication, expected to provide unprecedented levels of data rates, data security, and automation capabilities. In this context, integrating 6G into BCI systems would not only enhance the performance of brain-device communication, but would also create new opportunities for innovative applications. This work provides a comprehensive study on how BCI technology can be built effectively on top of 6G wireless networks by introducing several technical aspects and use cases. We first provide an overview of BCI and 6G, following their progression from early development to convergence through cognitive communication and advanced neural interfaces. We then highlight the need for the upcoming 6G systems toward BCI technology in every aspect, including 6G technologies such as intelligent edge and zero-touch networks, and 6G use cases such as digital twin, immersive communication, and internet of minds. Furthermore, we identify key technical challenges, open issues, and future research directions related to the 6G-enabled BCI paradigm.
